[Openmp-dev] AArch64 support

[Cownie, James H]

+if("${arch}" STREQUAL "32e" OR "${arch}" STREQUAL "32" OR "${arch}" STREQUAL "arm" OR "${arch}" STREQUAL "aarch64")
     set(FEATURE_FLAGS "${FEATURE_FLAGS} -D KMP_USE_ADAPTIVE_LOCKS=1")
     set(FEATURE_FLAGS "${FEATURE_FLAGS} -D KMP_DEBUG_ADAPTIVE_LOCKS=0")
endif()

Do you really want the adaptive locks for arm and aarch64?
Since they use the Intel specific transactional synchronization extensions (TSX) it seems unlikely to me.

Otherwise LGTM (though I have no testing environment for it).

Hi

Does anyone have a patch for AArch64 support? Either experimental, complete or notes/suggestions.

So here's a 1st draft for review - I don't expect it to be clean on the 1st pass, but getting some review would be really appreciated.

btw - Is anyone testing this on ARM or PPC64 regularly?

Thanks
