2001-12-08 21:24  simon

        * Parrot/PackFile.pm, docs/parrot.pod, docs/parrotbyte.pod,
        docs/vtables.pod, lib/Parrot/PackFile.pm:
        Getting the documentation up to scratch.

2001-12-08 21:21  simon

        * classes/pmc2c.pl:
        Allow inheriting from default class.

2001-12-07 20:43  gregor

        * examples/assembly/queens.pasm:
        Regenerated the file with the latest jakoc.

2001-12-07 20:29  simon

        * core.ops, t/op/stacks.t:
        Rename "rotate" to "rotate_up".

2001-12-07 20:15  simon

        * t/op/stacks.t:
        Some tests for rotate.

2001-12-07 00:55  gregor

        * core.ops:
        Cast the result of the pointer arithmetic, since without the cast
        there are warnings with some compilers, and without the parens
        around the pointer arithmetic, precedence breaks the meaning and
        causes crashes.

2001-12-06 23:37  simon

        * core.ops:
        Temporary. I prefer compiler warnings to segfaults, thanks.

2001-12-06 23:34  simon

        * runops_cores.c:
        Make "trace" work again.

2001-12-06 21:23  dan

        * Parrot/Test.pm, lib/Parrot/Test.pm: Undo twiddles to test.pm

2001-12-06 21:22  dan

        * core.ops, packfile.c, Parrot/Test.pm, include/parrot/stacks.h,
        lib/Parrot/Test.pm: Fix up source issues that made Dec C unhappy

2001-12-06 19:22  simon

        * core.ops:
        Yet another "How the *%$! did that compile?" moment.

2001-12-06 18:28  dan

        * hints/vms.pl: Fix to build, with a HERE logical required

2001-12-06 17:48  dan

        * core.ops, interpreter.c, pbc2c.pl, pdump.c, test_main.c,
        docs/parrot_assembly.pod, include/parrot/interpreter.h: Sensible
        changes to the interpreter--flags are now part of the interp
        structure.

        Courtesy of "Melvin Smith" <mrjoltcola@mindspring.com>

2001-12-06 14:02  gregor

        * docs/intro.pod:
        s/little_languages/languages/ in Jako section.

2001-12-06 13:15  simon

        * Makefile.in:
        Ensure the documentation gets made.

2001-12-06 13:12  simon

        * MANIFEST, docs/intro.pod:
        Documentation! Added the "Some Assembly Required" article with
        minor updates.

2001-12-06 00:39  simon

        * core.ops:
        More "eq" support.

        Courtesy of: Nguon Hao Ching <hao@netaxs.com>

2001-12-06 00:37  simon

        * test_main.c:
        Add the "-d" debug flag. Doesn't actually *do* anything yet.

        Courtesy of: Melvin <mrjoltcola@mindspring.com>

2001-12-06 00:11  tom

        * string.c, chartypes/unicode.c, chartypes/usascii.c,
        encodings/singlebyte.c, encodings/utf16.c, encodings/utf8.c,
        include/parrot/chartype.h, include/parrot/encoding.h,
        include/parrot/parrot.h: Moved string to number conversion code out
        of the encoding layer and into the main string layer as neither the
        encoding layer nor the character type layer knows enough on it's
        own to do the conversion correctly.

2001-12-05 23:12  tom

        * Makefile.in: Rebuild the classes directory if any of the object
        files for the classes are missing rather than only when perlint.o
        is missing.

2001-12-05 19:43  gregor

        * Parrot/Assembler.pm, lib/Parrot/Assembler.pm:
          * Reworked the constantize_string() stuff a little bit because it
        was
            puking on things like "\033[H\033[2J\0" (which occurs in the
            languages/jako/mandelzoom.jako example).

2001-12-05 19:39  gregor

        * languages/jako/: Makefile, mandelzoom.jako:
        Added 'mandelzoom' example.

2001-12-05 19:38  gregor

        * languages/jako/jakoc:
          * Added sleep()

          * Changed some instances of die() to confess()

2001-12-05 18:34  gregor

        * t/: op/pmc.t, pmc/pmc.t:
        s/sting->int/string->int/

2001-12-05 18:08  gregor

        * Parrot/.cvsignore:
        Ignore PMC.pm

2001-12-05 18:05  gregor

        * classes/.cvsignore:
        Ignore the generated files.

2001-12-05 17:19  gregor

        * pbc2c.pl:
          * Reverted recent changes, since they broke the script. Real fix
        coming
            later.

2001-12-05 17:03  simon

        * classes/Makefile.in:
        Remember: change Makefile.in, not Makefile. D'oh.

2001-12-05 17:02  simon

        * Makefile.in:
        Ensure PMC.pm gets remade.

2001-12-05 16:58  simon

        * MANIFEST, Makefile.in, classes/Makefile.in,
        classes/perlundef.pmc, include/parrot/pmc.h:
        Add perlundef class.

2001-12-05 16:45  simon

        * core.ops:
        Document "new P0, foo"

2001-12-05 16:43  simon

        * MANIFEST, Makefile.in, pbc2c.pl, pmc_pm.pl, Parrot/Assembler.pm,
        lib/Parrot/Assembler.pm, t/op/pmc.t, t/pmc/pmc.t:
        Allow assembler to know about PMC class names.

2001-12-04 13:39  ajgough

        * MANIFEST: Added t/op/pmc.t to MANIFEST.

2001-12-04 05:02  ajgough

        * classes/perlnum.pmc: Picky compiler pointed out probable thinko
        in perlnum.c

2001-12-04 04:24  ajgough

        * encodings/singlebyte.c, t/op/pmc.t, t/pmc/pmc.t: A much less
        broken form of strtod and appropriate tests.  Does not yet check
        for overflow.

2001-12-04 01:31  ajgough

        * string.c, encodings/singlebyte.c, encodings/utf16.c,
        encodings/utf8.c, include/parrot/encoding.h: Added length parameter
        to extract_num and extract_int string vtables, without this it
        would be impossible to have strings with nulls in while still
        knowing where they ended.

2001-12-03 18:40  ajgough

        * string.c, classes/perlstring.pmc, encodings/singlebyte.c,
        encodings/utf16.c, encodings/utf8.c, include/parrot/encoding.h,
        include/parrot/string.h: Moved pmc string to number conversion into
        the string encoding tables.

2001-12-03 00:21  ajgough

        * core.ops, t/op/pmc.t, t/pmc/pmc.t: Added set i, p and some tests
        for p-> integer.

2001-12-02 23:09  jgoff

        * classes/Makefile.in: Removed some redundant targets.

2001-12-02 19:02  ajgough

        * t/: op/pmc.t, pmc/pmc.t: Modified all pmc tests to make use of fp
        equality macro rather than using perl to generate expected output,
        all tests now have <<OUTPUT.

2001-12-02 17:44  ajgough

        * t/op/trans.t: Upgraded fp_eq and fp_ne macros to be more useful
        for pmc.t as well.  Will probably move macros into another file at
        some point, although this might be best left until the tests are
        unperled.

2001-12-02 06:16  jgoff

        * classes/pmc2c.pl: It wasn't properly setting the vtable index
        within Parrot_Perl{Class}_init.

2001-12-02 06:09  jgoff

        * classes/Makefile.in: I seem to have removed *$(O) twice..

2001-12-02 05:06  jgoff

        * Configure.pl, MANIFEST, Makefile.in: (Hopefully the last time...)
        Configure.pl - Removed '-I./include', added classes/Makefile
        generation MANIFEST     - Added classes/Makefile.in Makefile.in  -
        Removed old classes/* make stuff                Added target for
        classes/Makefile

2001-12-02 04:48  jgoff

        * classes/Makefile.in: Going to be used shortly...

2001-12-02 04:40  jgoff

        * docs/Makefile: Configure.pl - Added automatic makefile creation
        for docs/ and classes/                Removed '-I./include' because
        it was getting incorrectly                passed to classes/
        MANIFEST - added docs/Makefile.in, classes/Makefile.in Makefile.in
        - Removed classes/ build stuff, replaced with classes/Makefile.in
                    Added '-I./include' locally docs/Makefile - Should no
        longer be used, but I'm not brave enough to do a
        cvs delete.

2001-12-02 01:21  ajgough

        * t/op/trans.t: Refactored trans math tests to have hard coded
        expected return values and be more ready to be unperled at some
        point in the future.  Added $fp_equality_macro which is a
        "nearly-equal-to" function.

2001-12-02 01:18  ajgough

        Changing to use a Perl-style struct instead of the union cache.

2001-11-13 23:56  tom

        * string.c: Removed leading _ from string_index as function names

        Also fixed string_index to use the encoding routines instead of
        assuming a single byte encoding.

        string.c contains a bit of documentation explaining the logic

        platforms/win32.c, platforms/win32.h:
        Patch from Jason Diamond to make win32 platform stuff work:

        * Modified Configure.pl, mswin32.pl, and Makefile.in so that the
        platform specific files in the platforms directory gets copied to
        the correct directories. The Makefile will re-copy the platform.h
        and .c files if the original is modified.

        * #include platform.h in parrot.h instead of time.h.

        * Removed time.h and time.obj from the Makefile. time.h and time.c
        aren't being used anymore since that code was moved to linux.c and
        win32.c.

        * Renamed the BOOL typedef in parrot.h to BOOLVAL (inspired by
        INTVAL and FLOATVAL). This was conflicting with the BOOL typedef in
        windows.h. This required updating several files besides parrot.h.

        * Added a DEFAULT_OPEN_MODE to linux.h and win32.h and used that
        instead of the missing identifiers (on Windows) in core.ops in the
        calls to open.

        * Added Parrot_sleep and Parrot_setenv to both the linux and win32
        platform files and called those from core.ops. The Linux code for
        these functions came from core.ops so they should hopefully work.

            First attempt at getting this working across platforms. The
            macro WIN32 being tested might not be right.

          * New functions Parrot_intval_time() and Parrot_floatval_time()
            wrap the appropriate functionality depending upon platform.
            Changed core.ops to call these.

        Added obscure.ops with obscure transcendental ops.

        Added simple file I/O ops (close, open, read, write):

          * Initial versions Courtesy of Jeff <jgoff@speakeasy.net>

          * I changed some arg ordering stuff.

          * I added read/write of INTVALs and FLOATVALs.

        Added environment variable ops (getenv, setenv)

        Added system error ops (err(i) and err(s) for accessing errno and
        strerr().

        Moved print ops in with other "temporary" developer ops, since
        they'll move to a devel.ops or temp.ops oplib once we have oplibs.

        throw the darned thing away)

        * core.ops, languages/jako/jakoc:
          * New variants of the save ops to save constants on the stack.
        This is
            useful for saving zero arg and result counts on the stack, for
        example.

          * Modified jakoc to to adapt to the newly announced calling
        conventions.
            Even though Jako source code appears to show subroutines with
        fixed
            numbers of arguments and results, they are implemented with the
            variable count calling convention. Future modifications will be
        needed
            to ensure that an exception is raised if the stack frame is of
        the
            wrong size (or, at least that we pop the complete frame off).
        We'll
            also have to make more changes to support the true
        fixed-arg-count
            and fixed-result-count parts of the calling convention spec.

2001-10-21 15:20  gregor

        * examples/assembly/queens.pasm:
          * Modernize the calling conventions in queens.pasm. It was using
        swap,
            which now must be rotate. Also, changed to use return values on
        the
            stack instead of in I0.

2001-10-19 18:14  gregor

        * core.ops, stacks.c, include/parrot/stacks.h,
        languages/jako/jakoc:
        Per Dan's request, replacing 'swap' op by 'rotate'.

          * core.ops: Replaced 'swap()' by 'rotate(i|ic)'.

          * stacks.c and stacks.h: Removed swap-related functions from my
            prior commit, replacing them with stack_depth(), stack_entry()
            and rotate_entries().

            NOTE: The stack_depth() and rotate_entries() routines could
            be made more efficient through the caching of the sum of chunk
            'used' members from lower chunks in a field in the upper
            chunks. Also, if the interpreter's stack_base was changed to
            hold the pointer to the *top* chunk (since we usually come
            at the stack from the top down) instead of the *bottom*
            chunk. The code here at least works, and we can decide about
            bigger changes separately.

            For now, rotate only handles rotates in one direction and
            of magnituded one. A fully general rotate would do handle
            rotates in both directions and of arbitrary amounts. Again,
            this implementation is sufficient for current applications,
            and a feature-complete version can be developed if this turns
            out to be otherwise the right type of implementation.

            This change includes a new exception for ERROR_STACK_SHALLOW,
            meaning "not-empty-yet-not-deep-enough-for-what-you-asked".

          * jakoc: Changed the calling convention to use rotate instead
            of swap (of course). Also changed the convention for return
            value passing to use the stack as well.

        languages/jako/primes.jako, languages/jako/queens.jako,
        languages/jako/sub.jako:
          * New stack functions push_entry(), pop_entry() and swap_entry().
            The first two exist for the support of the last one. These
            functions don't care what is in the stack entries. These exist
            to support the new 'swap' op (see next bullet).

          * New op 'swap' for swapping the top two elements on the stack.
            This is necessary for passing arguments to functions, since
            the return address will be on top of any arguments that have
            been pushed on the stack. This way, you can use a (swap, pop)
            pair to retrieve each argument (for subroutine linkage).

          * Disassembler now prints numbers in decimal by default, with
            a new '-x' flag to turn on hexadecimal display. Since other
            members of the Parrot Tool Set use decimal by default, this
            makes it easier to compare output from the various tools.

          * Jako compiler has more explanatory comments and the following
            new features:

              * Lexically scoped variables.

              * Subroutines that take arguments and return values:

                  sub int foo(int bar) {
                    if (bar == 1) {
                      return 42;
                    } else {
                      return 13;
                    }
                  }
              * ... if (...) and ... unless (...) statement modifiers
                can be used on next, last and redo.

              * Bitwise and (&, &=) and or (|, |=) ops.

              * Type names are just 'int', 'num', 'str', and 'poly' now.
                The old long names 'integer', 'number', 'string', and
                'polytype' are no longer valid.

              * Integer variable assignments can now use 0b (binary),
                0 (octal) and 0x (hexadecimal) radix prefixes on literals.

          * New Jako and Parrot assembly examples queens.{jako,pasm} for
            solving the eight-queens problem. The assembly example is a
            hand-modified version of the assembly code produced by the
            Jako compiler from queens.jako. A few unnecessary ops have
            been removed, lots of unnecessary labels have been removed,
            and all the Jako source code comments have been removed.

          * Makefile and .cvsignore in languages/jako modified so that
            the assembler produces listings when assembling the programs,
            yet the *.list files are ignored by CVS.

          * Made the default target in languages/jako/Makefile 'all'.

          * Modified some of the Jako examples to use some of the new
            features of Jako, such as subroutines and lexical variable
            scoping.

        lib/Parrot/OpsFile.pm: Integrated op documentation.

          * core.ops now contains POD documentation of ops, interspersed
        with the
            ops themselves

          * Ops are organized into POD =head2 sections

          * Parrot/OpsFile.pm now treats the preamble of the ops file as
        anything
            up to the first POD directive OR op definition.

          * docs/Makefile now generates core_ops.pod from core.ops vi
        perldoc -u.

        * Configure.pl:
        Remove weird typo.

2001-10-14 10:56  tom

        * Configure.pl: Stop Configure trying to make op_info.c and op.h as
        op_info.c no longer exists and op.h is no longer a generated file.

2001-10-14 10:54  tom

        * Makefile.in: Added vtable.h to the list of things removed by the
        clean target.

        Moby Patch:

          * basic_opcodes.ops and opcode_table replaced by core.ops

          * process_opfunc.pl replaced by Parrot/OpsFile.pm, Parrot/Op.pm,
            and ops2c.pl. These convert *.ops to *_ops.c and
            include/parrot/oplib/*_ops.h

          * New ops2pm.pl converts *.ops to Parrot/OpLib/*.pm

          * disassemble.pl modified to use

          * interpreter.c modified to use structures in core_ops.c instead
            of the old op_info and op_func stuff. We're not yet to the
            point of handling multiple oplibs at a time, but we are getting
            there...

            Fingerprinting stuff disabled for now. We used to go off
            opcode_table. We need to rethink this. I have some ideas to
            make it unnecessary, but it remains to be seen whether others
            will like the direction they take us.

            Termination condition for while(){} loop in runops is now
            (pc) instead of (*pc). Any op can cause a HALT by returning
            a NULL pointer. Ops end, bounds and trace all do this. So, now
            the 'end' op body is actually executed, although all it does
            is HALT.

          * Makefile.in modified to perform a test build using pbc2c.pl,
            which is the bytecode --> C compiler I've posted to the
            list before.

          * Op full names are now autogenerated. Op root names must not
            contain underscores, so some op renamings have happened.
            Such as clear_i becoming cleari.

2001-10-13 11:49  simon

        * Configure.pl, MANIFEST:
        Make parrot actually build again.

        * MANIFEST: Shouldn't have added vtable.h to the manifest...

2001-10-10 17:54  dan

        * MANIFEST, stacks.c, vtable_h.pl, Parrot/Vtable.pm,
        lib/Parrot/Vtable.pm: Now spits out the #defines for the various
        vtable type entries properly

        new format vtable.tbl file...

2001-10-10 15:32  dan

        * vtable.tbl: New Column to indicate the type of the vtabel entry
        so we can know how many slots it takes

        * Parrot/Vtable.pm, lib/Parrot/Vtable.pm, vtable_h.pl: Patch to
        allow parrot to compile.  PACKAGE is not defined, therefore, I
        added a struct before it to have it not complain until we define
        PACKAGE.  Also, there was an extra shift in Vtable.pm and a missing
        semicolon at the end of the struct declaration.

        support for generating the vtable function table offset macros

2001-10-10 01:05  simon

        * t/op/integer.t:
        The test for cmod_i was using the 'mod Ix, Ix, Ix' form which

        what it thought it was.

2001-10-08 15:04  gregor

2001-10-08 14:56  gregor

        * basic_opcodes.ops:
          * Fixed a couple of typos.

2001-10-08 14:45  gregor

        * basic_opcodes.ops, opcode_table, t/op/integer.t, t/op/number.t:
        Arithmetic enhancements:

          * Renamed existing mod_i as cmod_i and added "corrected" mod_i:

            NOTE: This "uncorrected mod" algorithm uses the C language's
        built-in
            mod operator (x % y), which is

                ... the remainder when x is divided by y, and thus is zero
        when y
                divides x exactly.
                ...
                The direction of truncation for / and teh sign of the
        result for %
                are machine-dependent for negative operands, as is the
        action taken
                on overflow or underflow.
                                                                     --
        [1], page 41

            Also:

                ... if the second operand is 0, the result is undefined.
        Otherwise, it
                is always true that (a/b)*b + a%b is equal to z. I both
        operands are
                non-negative, then teh remainder is non-negative and
        smaller than the
                divisor; if not, it is guaranteed only that the absolute
        value of the
                remainder is smaller than the absolute value of the
        divisor.
                                                                     --
        [1], page 205

            This op is provided for those who need it (such as
        speed-sensitive
            applications with heavy use of mod, but using it only with
        positive
            arguments), but a more mathematically useful numeric mod based
        on
            floor(x/y) and defined with y == 0 is provided by the mod_i op.

        Programming
                  Language*, Second Edition. Prentice Hall, 1988.

          * Added "corrected" mod_i:

            NOTE: This "corrected mod" algorithm is based on the C code on
        page 70
            of [1]. Assuming correct behavior of C's built-in mod operator
        (%) with
            positive arguments, this algorithm implements a mathematically
        convenient
            version of mod, defined thus:

              x mod y = x - y * floor(x / y)

            For more information on this definition of mod, see section 3.4
        of [2],
            pages 81-85.

          * Added mod_n, using the same formula as above, but with FLOATVAL
            arguments.

          * Added cmod_n, using the C math library's fmod() function:

            NOTE: This "uncorrected mod" algorithm uses the built-in C math
        library's
            fmod() function, which computes

                ... the remainder of dividing x by y. The return value is x
        - n * y,
                where n is the quotient of x / y, rounded towards zero to
        an
                integer.
                                                -- fmod() manpage on RedHat
        Linux 7.0

            In addition, fmod() returns

                the remainder, unless y is zero, when the function fails
        and errno
                is set.

            According to page 251 of [1], the result when y is zero is
        implementation-
            defined.

            This op is provided for those who need it, but a more
        mathematically
            useful numeric mod based on floor(x/y) instead of truncate(x/y)
        and
            defined with y == 0 is provided by the mod_n op.

2001-10-07 16:27  gregor

        * basic_opcodes.ops, interpreter.c, opcode_table,
        process_opfunc.pl, test_main.c, include/parrot/interpreter.h,
        t/trace.pasm:
          * Two new ops, trace_ic and bounds_ic that twiddle bits in
            interpreter->flags and set interpreter->resume_addr.

          * Two new runops core variants, so now we cover the relevant
            flag space over {trace, notrace} x {boundscheck, noboundscheck}

          * Runops core selection that converts the flags into an index
        into
            a core table (runops_cores) to get the core function pointer.

          * A new trace_op variant that doesn't do bounds checking (used by
            the non-bounds-checking-but-tracing runops core).

          * PC is passed into the cores so that they can be used when
            resuming (they used to assume starting at the beginning of the
            code, which would thwart resumption).

          * runops() itself is changed to have a while() loop in it so that
            any time we drop out of the core, we'll resume if we have an
            interpreter->resume_addr set (after reselecting the core,
        though).

          * process_opfunc.pl has a new "macro": RESUME(), that sets up
            interpreter->resume_addr. This is used by the new ops. The new
            ops still return the new PC as the next op (which MUST be an
            'end' op to force the core loop to terminate -- *pc being false
            is the only termination condition we can count on for all
        cores).

          * New interpreter flag: PARROT_BOUNDS_FLAG, used to control
            bounds checking core selection.

          * test_prog now has a '-b' flag in addition to the '-t' flag.
        Now,
            bounds checking is off by default (I saw a performance boost:
            6.3 Mop/s with -b, 7.0 Mop/s without).

          * A new sample/test program: t/trace.pasm that twiddles the trace
            flag while it is running.

        * .cvsignore, Makefile.in, build_interp_starter.pl, interpreter.c,
        include/parrot/.cvsignore, include/parrot/interpreter.h:
        Now that 0.0.2 is released, I can clear out the backlog of approved
        but uncommitted patches. Here's one Dan approved on 2001-09-21
        (Simplified DO_OP):

          * test_prog and pdump are linked with only the files the need,
        not
            al the files.

          * build_interp_starter.pl writes out op_info.[hc], too. These
        files
            contain op name, arg count and arg type information. This will
        be
            useful for multiple things in the future, including better
        trace
            output and the crystalizing loader.

          * The DO_OP macro is now simpler and doesn't require explicit
            temporaries.

          * interpreter.c is modified to use the new op info in tracing
        output.

          * The interpreter just points its opcode_funcs and opcode_info
            members at the default tables rather than allocating memory on
            the fly.

        This patch ensures that all bytecode is of type opcode_t except for
        the constant table constants.  That means that almost all of the
        INTVALs in the code were replaced with opcode_t and the i pack type
        was replaced with the op pack type in calls to pack_arg and such.
        Also, since it has been declared that ALL integer constants are to
        be 32 bits, some test cases were changed to ensure that an integer
        constant was no bigger than 2 ** 31.

        process_opfunc.pl was also cleaned up to no longer look at either
        opcode_table or interp_guts.h but gather all of its information
        from Opcode.pm.

        The Assembler.pm module was changed to do late binding of arguments
        so that 0 could be treated like 0.0 without having to be so
        declared.  Also, only strings now use the [sc:N] intermediate form
        as it was unnecessary for integer and float types.

        t/op/basic.t:
          * Added new syntax to the assembler to allow square-bracket
            arithmetic expressions involving (global) labels, the current
            instructions base address ('@'), numeric constants (not
        equates)
            and basic arithmetic operators (+, -, *, / -- although + and -
            are likely to be the only ones used in practice).

          * Fixed a bug in Parrot/Assemble.pl that caused macro expansion
        to
            fail (argument passing wasn't working).

          * Enabled t/op/basic.t's last test, which is actually a copy of
        the
            code from t/call.pasm. Now all tests there are enabled and
        working.

          * Added new example/test program t/call.pasm to demonstrate
        working
            macros and poor-man's subroutine calls

          * Added header comments to t/*.pasm

        include/parrot/packfile.h, include/parrot/string.h:
        Move NVs to the constant table.    * Changes to Types_pm.in to make
        life easier for some of the      packing/etc. I'm doing elsewhere.
        Also, we now pack 'n' as      'i'.

          * Moved the guts of assemble.pl to Parrot/Assembler.pm so that
            eventually we can use all these tools together inside scripts
            rather than call out to the shell to run the programs.

          * As I was tracking down problems, I converted the internal
            documentation of the assembler to POD from comments.

          * Changed the numeric regexp in the assembler to detect leading
            signs and trailing exponents.

          * Updated basic_opcodes.ops to fetch numeric constants from the
            constant table.

          * Enhanced the disassembler in a number of ways to make my life
            easier while tracking down bugs (try it out). It now puts in
            labels for ops that are the destinations of flow control ops.

          * packfile.c now has a TRACE_PACKFILE switch that can be set
            to get it to print info as it processes. I needed this while
            debugging, but I can remove it or change it before committing
            if its a problem.

          * Updated pdump.c because it was missing a call to init_world().

          * Updated process_opfunc.pl to deal with numeric constants
            being stored in the constant table instead of inline.

          * Added multiple type support to Parrot/PackFile/Constant.pm

          * Added Parrot/String.pm, to be used for constants.

          * Added packfile.[hc] functions for allocating new constants
            of various types.

          * Made string_copy visible to the world in parrot/string.h.

        Wow.

        * assemble.pl: This patch makes integer constants of the form
        0b[01]+ work with perl 5.005.  The oct function in versions of perl
        before 5.6 did not handle the 0b numeric prefix; therefore, it was
        returning 0.  To fix this, I added a from_binary function that
        would take a binary string and return its decimal representation.
        Now, instead of blindly calilng oct, it makes a distinction between
        0/0x numbers and 0b numbers.

          * bytecode.[hc] removed. packfile.[hc] are the interface to the
            packfile/bytecode file from C. May be renamed in the future.

          * packfile.[hc] changed to use 'struct PackFile *', etc. instead
            of 'PackFile *', just like the interpreter, etc.

          * Constants are accessed via the interpreter's 'code' member
            (struct PackFile * code). Macros PCONST(i) and PNCONST are
            provided to access constants by index and the number of
            constants, respectively (assumes a variable 'interpreter' of
            the appropriate type is in scope).

          * Byte Code is accessed via the interpreter's 'code' member.

          * Changed PackFile_Constant to point to a STRING instead of
        having
            members for the string_make() arguments. Also has a 'type' IV
            in preparation for allowing multiple types of constants in
            const_table.

          * Removed hardcoded example program from test_main.c. We have
            plenty of test programs elsewhere.

          * test_prog now uses a PackFile to deal with the program before
            sending it on to the interpreter.

          * Added missing 'end' ops to some tests in t/op/integer.t and
            t/op/stacks.t.

        This patch does two only somewhat related things.

        Parrot/Opcode.pm:  Change the hard-wired assumption that sizeof(nv)
        = 2*sizeof(iv) to a PConfig-type computed value.

        Parrot/Test.pm:  Change it to run with the perl that was used to
        generate this version of Parrot.  This is useful if, for example,
        you want to use bleadperl to build and test parrot (e.g. to try out
        various 64-bit options) but you still have a 5.6.x (or 5.005_xx)
        installed as the default 'perl' on your system.  Since perl-5.7.x
        is installed 'version-only', a plain 'perl' is quite likely to pick
        up the older perl in such cases. Such an older perl might well not
        understand pack('q') used in the assembler.

        function to only use 2 args, but the opcode_table still had three
        listed.  Fixed integer.t and number.t to use the new comparison
        operators.  Improved assemble.pl ability to grok operators by
        constructing a function set and comparing operator types.

        Mostly

        lib/Parrot/PackFile/Constant.pm, lib/Parrot/PackFile/FixupTable.pm:

        Functions for reading, writing and manipulating Parrot Pack Files.
        NOTE: This is a proposed term based on the fact that the file
        contains more than just byte code, and another language (Java)
        calls its binary files by a broader notion of what's in them (Class
        Files). Since Perl has packages, and since we use pack() to write
        them, we'll call them PackFiles (at least for now).

        That does, however, beg the question of file extension. Should we
        name the files "foo.pack" instead of "foo.pbc"?

2001-09-17 20:23  thgibbs

        * build_interp_starter.pl, bytecode.c, bytecode.h, interpreter.c,

          * Provides macros in interp_guts.h for setting up arrays with
            op names and op arg counts (done via build_interp_starter.pl).

            These are used in the op tracing

          * The functions in bytecode.[hc] pass around a pointer to the
        length
            of the bytecode so that later when we get to runops, we know
            how much bytecode we've got and we can detect out-of-bounds
            jumping. The documentation is updated, too.

          * runops in interpreter.c now looks at interpreter->flags to
            decide if the core of runops should be runops_trace_core or
            runops_notrace_core. These new functions contain just the
            while-loop portion of runops. A new function runops_generic
            does any other setup (such as checking the bytecode
            fingerprint) or wrapup (such as complaining if we ended up
            out-of-bounds). NOTE: I didn't know what we should do for
            functions in here that are not part of the api, so I gave
            them docs with 'TODO' marks mentioning they really aren't
            part of the api. Guidance appreciated.

          * test_main.c now checks for '-t' arg and sets the tracing flag
            on its interpreter instance as appropriate.

2001-09-17 17:47  bdwheele

        * languages/jako/jakoc:
        Modified comparison implementation to use temporary registers in
        the case of register-constant and constant-register comparisons.
        This will allow the compiler to emit code that works when the
        constant-comparison ops are backed out of Parrot. If the ops ever
        make their way back in, then jakoc can emit more efficient code
        again.

        more conditionals to while and if   * revert to using implicit
        opcodes in a few cases that were broken     before the assembler
        patch went in recently.

        * assemble.pl, basic_opcodes.ops, opcode_table:
        From Brian Wheeler:

        This patch gives the assembler support of '\a','\n','\r','\t', and
        '\\' in string constants.

        In addition, it changes (for all registers) "I reg %li is ..." to
        just the value of the register.  Printing constants is also
        supported, but alas, you have to specify the type (print_sc,
        print_ic, print_nc).

        Brian Wheeler's big patch:

        * Changes the opcode_table file to provide additional information
        about the operands.  Case shouldn't be a problem since that data
        never becomes a C symbol [this is pretty much as before]

        * Padding errors solved:  assemble.pl and bytecode.c were padding
        the constants incorrectly.  It should have been 4-(size % 4), not
        just (size % 4).  It is now fixed in both places.

        * assembler has less special cases, and should be easier to hang
        error checking on

        * disassembler dumps constant table and the format is a bit
        prettier, including register names, etc.

        * Makefile, TODO, assemble.pl, basic_opcodes.ops,
        build_interp_starter.pl, disassemble.pl, make_op_header.pl,
        opcode_table, process_opfunc.pl:
        Automatic opcode numbering, from Leon Brocard <acme@astray.com>.
        This means we can add lots more opcodes without fiddling about with
        the numbers. Hooray!

        Don't forget that "end" needs to be op zero, else the interpreter
        falls off the end of the code. This is Bad, and I wonder if there's
        a way around it.

        * MANIFEST, make_op_table_build.pl:
        Hey! This doesn't do anything...

2001-09-10 19:46  simon

        * Makefile:
        "clean" target cleanup from Bryan C. Warnock <bwarnock@raba.com>.

2001-09-10 18:31  simon

        * MANIFEST:
        You know what this means...

2001-09-10 18:30  simon

        * assemble.pl:
        "use strict" patch from Leon Brocard <acme@astray.com>. Hey, why
        wait for a release...? :)

2001-09-10 18:13  simon

        * interpreter.c:
        Bad Dan! No cookie!

2001-09-10 17:56  simon

        * README:
        A *real* README file, which doesn't claim it isn't for public
        consumption.

2001-09-10 17:02  simon

        * TODO:
        More things to do.

2001-09-10 16:56  dan

        * TODO: Added in assembler gripe. Also added a few blank lines for
        clarity

2001-09-10 16:49  dan

        * register.h, register.c: Renamed the core functions so the opcodes
        can find 'em OK. (There were some conflicts)

2001-09-10 16:48  dan

        * basic_opcodes.ops, opcode_table: Added register window ops

2001-09-10 11:07  simon

        * TODO:
        Trivial TODO list.

2001-09-10 11:05  simon

        * test.pbc, test2.pasm, test_main.c: Other string bits and pieces;
        note "-s" flag to test prog.

2001-09-10 11:01  simon

        * docs/strings.pod:
        New string documentation.

2001-09-10 11:01  simon

        * basic_opcodes.ops, opcode_table:
        String ops.

2001-09-10 10:53  simon

        * global_setup.c:
        More string fu.

2001-09-10 10:51  simon

        * memory.h:
        Just some more aliases for now. Used by string handling stuff.

2001-09-10 10:50  simon

        * assemble.pl, bytecode.c, bytecode.h:
        Temporary hack to store string constants in bytecode and recreate
        them at runtime.

2001-09-10 10:48  simon

        * op.h:
        op.h is now generated by the Makefile; remove it.

2001-09-10 10:47  simon

        * Makefile:
        clean and op.h Makefile targets.

2001-09-10 10:45  simon

        * string.c, string.h, strnative.c:
        More string vtable stuff.

2001-09-07 21:07  dan

        * assemble.pl:

        Much less picky about whitespace in the opcode_table now. (Doesn't
        whine on blank lines)

2001-09-07 16:23  dan

        * Makefile, assemble.pl, global_setup.h, interpreter.c,
        interpreter.h, opcode_table, parrot.h, test.pasm: (Here's hoping
        this takes) Added global_setup.h to declare init_world function

        Moved variable declarations out of the interpreter loop for small
        speed boost.

        Changed end opcode to now be opcode #0. A function is provided for
        it, but isn't ever executed.

        When the interpreter sees an opcode 0 in the stream it means the
        end of stream. Things were coring on Cygwin otherwise. (I think I
        was dereferencing a zero, which is bad)

2001-09-06 22:07  dan

        * basic_opcodes.ops, process_opfunc.pl:

        Minor tweaks to basic_opcodes.ops to fix some NV issues. The rest
        are minor changes now that things are in a fixed state.

2001-09-06 16:13  dan

        * basic_opcodes.c, test_opcodes.c:
        test_opcodes.c is now irrelevant--they're all in basic_opcodes.ops.

        basic_opcodes.c is now autogenerated from basic_opcodes.ops, and
        should be nuked. So it is. :)

2001-09-06 03:35  dan

        * basic_opcodes.ops, build_interp_starter.pl, process_opfunc.pl:
        Scripts to build the header file that holds the function table
        creation code, as well as the script to turn an opcode file to C
        source. (And the basic opcode functions turned into an opcode
        source file)

2001-09-06 03:31  dan

        * Makefile, interpreter.c:
        Changes to support the autogeneration of the opcode function
        pointer table in interpreter.c, along with the changes to the
        Makefile needed.

2001-09-05 13:27  simon

        * bytecode.c, config.h, docs/opcodes.pod, docs/overview.pod,
        docs/parrotbyte.pod, docs/vtables.pod:
        Added stubs for the documents; working on them this week. (What's
        left of it.) config.h change is just to type VTABLE, and the
        bytecode thing you might want to revoke. It's apidoc for the
        functions in there.

2001-09-03 18:26  simon

        * docs/strings.pod:
        A start on the string API documentation.

2001-09-03 17:43  simon

        * opcode_table:
        Since we specify the opcode number, we can rearrange to a more
        human-friendly ordering.

2001-09-03 17:42  simon

        * basic_opcodes.c:
        Coupl'a logic bugs. (I think)

2001-09-03 17:41  simon

        * string.c, string.h, strnative.c:
        Tidying up the string vtables.

2001-09-03 17:38  simon

        * make_op_header.pl:
        Spit out the whole of op.h, not just the bit in the middle.

2001-08-29 13:16  ask

        * README: it seems like we indeed can commit. What about sending
        commit mails?

2001-08-29 13:07  simon

        Initial checkin of Simon's work directory - Dan, feel free to nuke.
         I'm still working on the string stuff, though.
