I posted a patch that adds SSE2/SSSE3 versions of precompute_partition_info_sums_().
I didn't remove the old code; just changed "#if defined ..." to "#if defined ... && 0".


Currently there are two useless asm files:
* bitreader_asm.nasm (defines FLAC__bitreader_read_rice_signed_block_asm_ia32_bswap)
* stream_encoder_asm.nasm (defines precompute_partition_info_sums_32bit_asm_ia32_)
and I doubt that they will become useful again.


BTW, after removing bitreader_asm.nasm from build it will be possible to remove
local_bitreader_read_rice_signed_block from struct FLAC__StreamDecoderPrivate
and call FLAC__bitreader_read_rice_signed_block() directly (IOW, revert the patch

Or to make bitreader_read_from_client_() function static again (it was static before
