Dear friends, while version bumping sci-libs/fftw, I've noticed our CPU_FLAGS_X86 list could be expanded a bit:
avx512 - introduced with Skylake and Knights Landing I also propose creating a CPU_FLAGS_PPC variable containing (at least): altivec - PowerPC's SSE vsx - PowerPC's AVX Finally, I also propose creating CPU_FLAGS_ARM variable containing: neon Any ideas? Currently cpu-feature flags for non-x86 are package local, whereas making them globally available makes masking easier for non- applicable archs etc. and makes enabling them easier for users. David
