git/ppc, branch v1.4.2

Fix more typos, primarily in the code

2006-07-10T07:36:44Z

The only visible change is that git-blame doesn't understand "--compability" anymore, but it does accept "--compatibility" instead, which is already documented. Signed-off-by: Pavel Roskin Signed-off-by: Junio C Hamano

A better-scheduled PPC SHA-1 implementation.

2006-06-24T10:02:00Z

This is about 15% faster that the current sha1ppc.S on a G4, and 5% faster on a G5 when hashing 10 million bytes, unaligned. (The G5 ratio seems to get better as the sizes fall.) It's also somewhat smaller, due to using load-multiple instructions. No copyright is claimed on the changes to Paul Mackerras' work below.

Fix PPC SHA1 routine for large input buffers

2006-06-19T03:12:20Z

The PPC SHA1 routine had an overflow which meant that it gave incorrect results for input buffers >= 512MB. This fixes it by ensuring that the update of the total length in bits is done using 64-bit arithmetic. Signed-off-by: Paul Mackerras Signed-off-by: Junio C Hamano

[PATCH] PPC assembly implementation of SHA1

2005-04-23T06:08:43Z

Here is a SHA1 implementation with the core written in PPC assembly. On my 2GHz G5, it does 218MB/s, compared to 135MB/s for the openssl version or 45MB/s for the mozilla version. Signed-off-by: Paul Mackerras Signed-off-by: Linus Torvalds
