Subject: [X86][AVX512] _mm512_stream_load_si512 should take a void const* argument (PR33977)
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=98367161436d661c328c88d5eb82ce4b40e264fa;p=clang

[X86][AVX512] _mm512_stream_load_si512 should take a void const* argument (PR33977)

Based off the Intel Intrinsics guide, we should expect a void const* argument.

Prevents 'passing 'const void *' to parameter of type 'void *' discards qualifiers' warnings.
