Subject: [PATCH v2 00/14] ARM improvements
Date: Fri, 01 Mar 2013 17:36:00 -0000 [thread overview]
Message-ID: <1362159320-5934-1-git-send-email-rth@twiddle.net> (raw)
I believe I've now addressed all of the comments to date.
Patches 4-8 have been approved, but they touch the same code
as patches 1-3, so I'm not rearranging them.
Patch 1 -- Spurious whitespace changes removed.
Patch 2 -- I never saw a review for this one?
Patch 3 -- Totally rewritten, in preparation for new patch for hard-tp.
Patch 6 -- Review mentioned deleting __APCS_32__, but this was already
done in patch 7, so I didn't rearrange that.
Patch 9-10 -- New.
Patch 11-12 -- Micro-optimization suggestions from Mans Rullgard applied.
Patch 14 -- Adjusted to avoid r9.
I've yet to test the string routines on big-endian. I'll delay
re-posting those until I have done so.
