-march=is unsupported on PPC, but it is used in a fallback, therefore breaking the build on macOS PPC (and likely Big Endian FreeBSD, Linux etc).I have used
-DHPTT_ARCH_IBMfor Apple here, since the code appears Altivec-compatible and builds fine. However once/if insns from ISA newer than 2.03 are added, non-VSX code should be retained separately for cases where those are unsupported, and then-DHPTT_ARCH_PPCwill be needed.P. S. I suspect that a separate case may be needed for Apple Clang on Intel, since it does not support OpenMP (at least most of its versions). But keeping this PR to PPC.
