Hello everyone! I recently ran into build failure in the upcoming nodejs24, on i686 architecture (yay!). It seems like some of the sse vector instructions are not defined, on just this arch:
``` ../../deps/v8/src/strings/string-hasher.cc: In static member function ‘static uint64_t v8::internal::ConvertTo8BitHashReader::Read64(const uint8_t*)’: ../../deps/v8/src/strings/string-hasher.cc:28:12: error: ‘_mm_cvtsi128_si64’ was not declared in this scope; did you mean ‘_mm_cvtsi32_si64’? 28 | return _mm_cvtsi128_si64(_mm_packus_epi16(x, x)); | ^~~~~~~~~~~~~~~~~ | _mm_cvtsi32_si64 ../../deps/v8/src/strings/string-hasher.cc: In static member function ‘static uint64_t v8::internal::ConvertTo8BitHashReader::Read32(const uint8_t*)’: ../../deps/v8/src/strings/string-hasher.cc:49:12: error: ‘_mm_cvtsi128_si64’ was not declared in this scope; did you mean ‘_mm_cvtsi32_si64’? 49 | return _mm_cvtsi128_si64(_mm_packus_epi16(x, x)); | ^~~~~~~~~~~~~~~~~ | _mm_cvtsi32_si64 ``` I tried digging around in the relevant headers (emmintrin.h) and did not find any defines that would hide the _mm_cvtsi128_si64 on i686. Can anyone enlighten me about what is going on? Side note, the code that is trying to call this has an alternative path for processors that do not support the SSE2 instructions, so if the solution for this would be "undefine __SSE2__", it would be viable. I would just like to figure out what is going on first.
