URL: https://github.com/llvm/llvm-project/commit/12dc13b73cf8c11da1bcc354c78bd6a9c92408e8 DIFF: https://github.com/llvm/llvm-project/commit/12dc13b73cf8c11da1bcc354c78bd6a9c92408e8.diff LOG: prfchwintrin.h: Make _m_prefetchw take a pointer to volatile (PR49124) For some reason, Microsoft declares _m_prefetch to take a const void*, but _m_prefetchw to take a /volatile/ const void*. Do the same for compatibility.
