MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by maikmerten -I don't expect hmp3 to generate identical files for Visual Studio, GCC 10.x or GCC 13.x, let alone if different instruction sets are involved.
i586 uses the x87 instruction set for floating point.
i686 uses the SSE instructions for floating point.
The Visual Studio compiles with ASM use a mixture of x87 instructions and SSE.
The Win64 x86_64-builds can use SSE(2)
I think Case's builds were AVX-enabled.
