2009-08-06block-sha1: get rid of redundant 'lenW' contextLinus Torvalds
.. and simplify the ctx->size logic. We now count the size in bytes, which means that 'lenW' was always just the low 6 bits of the total size, so we don't carry it around separately any more. And we do the 'size in bits' shift at the end. Suggested by Nicolas Pitre and linux@horizon.com.

2009-08-06Add new optimized C 'block-sha1' routinesLinus Torvalds
Based on the mozilla SHA1 routine, but doing the input data accesses a word at a time and with 'htonl()' instead of loading bytes and shifting. It requires an architecture that is ok with unaligned 32-bit loads and a fast htonl(). Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
