Fix SIGSEGV when compiled with -march=znver4 #19

Closed

AngryLoki wants to merge 1 commit into ROCm:develop from AngryLoki:fix-unaligned-store

Commits on Oct 18, 2023

Due to unaligned allocations, library crashes in nontemporalMemcpy

in _mm512_stream_si512 (which requires 64-aligned allocations,
but used to copy default-aligned objects).

As it is seemingly difficult to change allocations for copied
objects (common objects with ref-counts), the fix just replaces
nontemporalMemcpy with normal memcpy, which is already optimized
in most versions of C runtime.

Closes ROCm#18
