About disable SSE2 #28

Closed 123toorc closed 3 years ago

123toorc commented 3 years ago

Hi, I'm working on the project that is going to integrate the sod as a benchmark. Unfortunately, we are blocked at the compilation stage, our environment set up let us we can't support SSE2. We have plenty of error regarding: for example: always_inline function '_mm_load_si128' requires target feature 'sse2', but would be inlined into function 'stbi__idct_simd' that is compiled without support for 'sse2' is that possible there is some alternative function as _mm_load_si128 _mm_set1_epi32 _mm_set1_epi16, etc. It is inside the sod_img_reader.h.

On x86, SSE2 will automatically be used when available based on a run-time test; if not, the generic C versions are used as a fall-back. If for some reason you do not want to use any of SIMD code, or if you have issues compiling it, you can disable it entirely by defining STBI_NO_SIMD.
