Ported over the more efficient linux crc32() function. A quick comparsion on ppc: After changing the old crc32 to do 4 bytes in the inner loop to be able to compare with new version one can note: - old inner loop has 61 insn, new has 19 insn. - new crc32 does one 32 bit load of data to crc while the old does four 8 bits loads. - size is bit bigger for the new crc32: 1392(old) 1416(new) of text. The is because the new version shares code with crc32_no_comp() instead of duplicating code. - about 33% faster on ppc: New > crc 0 0xfffffff -> 39 secs Old > crc 0 0xfffffff -> 60 secs Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> |
