Register width was increased to 256 bit with the introduction of AVX (YMM0-8 on i386 and YMM0-15 on amd64, respectively) but their number was not changed until AVX-512, which again increased register width to 512 bit, and increased the number of the ZMM registers to 32. But if I am not mistaken, we don't have AVX-512 code in libFLAC yet :-) In any case, the disable-SSE matter is still important. People are still using flac on x86 machines without SSE, for instance AMD Geode CPUs seem to live forever.
