games-emulation/vbam-2.0.0_pre1507 attempts to use hand-written assembly code when the MMX feature is enabled. This results in multiple build errors similar to "admame.cpp:354: Error: incorrect register `%rsi' used with `l' suffix". Disabling MMX support fixes the problem. Reproducible: Always Steps to Reproduce: 1. Add mmx to CPU_FLAGS_X86 2. emerge vbam 3. note build failure Actual Results: build fails due to incorrect assembly for amd64 targets Expected Results: successful build If I understand ebuild writing guidelines correctly, an appropriate fix would be to mask the cpu_flags_x86_mmx USE flag for vbam and amd64 profiles. I also believe the previous version of vbam is unaffected as it does not have an optional MMX optimization path.

Created attachment 416138 [details] build log demonstrating assembly errors
I can confirm seeing the same issue on my systems.
well darn. I thought I had tried that but I guess not. If it doesn't work on amd64 them I'm not that interested so I punted the mmx stuff for now.
