Now runtime detection of CLMUL support can pick between the CLMUL and the generic assembly implementations. Whatever overhead this has for builds that omit CLMUL completely isn't important because builds for any non-ancient system is likely to include the CLMUL code too. Handle the CRC tables in crcXX_fast.c files because now these files are built even when assembly code is used. If 32-bit x86 assembly is enabled then it will always be built even if compiler flags were such that CLMUL would be allowed unconditionally. That is, runtime detection will be used anyway. This keeps the build rules simpler. In LZ encoder, build and use lzma_lz_hash_table[256] if CLMUL CRC is used without runtime detection. Previously this wasn't needed because crc32_table.c included the lzma_crc32_table[][] in the build unless encoder support had been disabled. Including an 8 KiB table was silly when only 1 KiB is actually used. So now liblzma is 7 KiB smaller if CLMUL is enabled without runtime detection. |
