amd64 --optimize

Reported by: adougherty Owned by: rurban
Priority: major Milestone: 1.0
Component: none Version: trunk
Severity: high Keywords: 64bit

Patch status: applied Platform:


This is a guess for a workaround that might make --optimized builds work on amd64. Could someone who has an amd64 system give it a spin and report back? If it works, could someone apply it?

Ideally, the entry should be conditional on arch == 'amd64', but I don't know how to do that in Parrot's Configure/build system.

I adapted it to our build compiler. Thanks. Can someone on amd64 test this?

#IF(cpuarch==amd64):src/gc/system.c  -{@optimize@}

is the syntax and a target eq CFLAGS rule had to be added to genfile.

I ran this with the patch provided by rurban. After trying the original patch, which also gave the same results.

I ran perl Configure,pl --optimize --test, make world and make test on Kubuntu Intrepid AMD64 with the latest updates and similarly for CPAN. Build at r37128.

This is the first time I have managed to get an --optimize(d) build on this platform.

The make test results are as follows:

Building without the --optimize (and without the patch) gives the same results.


I did not use make smoke with the --optimize build as the patch has not yet been applied.

The file's only 300 lines long, with four functions. An easy binary chop should determine which part's the problem (lines 94 - 115 look relevant).
