Description Samuel Holland 2020-10-14 02:27:14 UTC

I have /etc/portage shared between amd64, arm64, and ppc64 boxes. I just had x11-libs/pixman fail to build on arm64 with:

  ../pixman-0.40.0/meson.build:243:2: ERROR: Problem encountered: vmx Support unavailable, but required

This comes from `$(meson_feature cpu_flags_ppc_altivec vmx)` in the ebuild.

I have in my make.conf:
CPU_FLAGS_PPC="altivec vsx vsx3"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 sse4_1 ssse3"

I note that cpu_flags_arm_* and cpu_flags_x86_* are masked by default, and they are unmasked on the appropriate architecture. I believe the same should be done for cpu_flags_ppc_*. That would cause cpu_flags_ppc_altivec to be ignored on arm64, which would fix the build error.
