Parrot Deprecations for 3.0
Indirect Register Access Ops
Opcodes that access registers that are not their direct arguments are deprecated. Note, however, that direct arguments does include keys and pcc ops.
They don't fit well with the level of the rest of parrot's opcodes. They make register lifetime analysis impossible, preventing many optimizations.
If you really are using this, rethink your code. Stop using the register frame as an aggregate. Use an object aggregate in stead.
The exchange ops are deprecated.
They operate at too low a level to be useful as parrot ops.
You aren't using this. Seriously?
.macro xchg_int(a, b) $I0 = .a .a = .b .b = $I0 .endm
PIR string literals with charset and encoding are deprecated
PIR string literals of the form
After the charset/encoding merge, they're unneeded.
They can be replaced with
The encoding should be one of the new unified encodings.
Remaining string_* functions are deprecated
The string_* functions have been deprecated for a while. The remaining functions are:
string_make string_ord string_chr string_to_cstring_nullable string_max_bytes string_increment
They're old cruft.
string_make should be replaced with Parrot_str_new_init. You can use Parrot_find_encoding to get an encoding from a cstring.
Replace string_ord with Parrot_str_indexed.
Replace string_chr with Parrot_str_chr.
Replace string_to_cstring_nullable with Parrot_str_to_cstring.
string_max_bytes and string_increment will be removed.
