Subject: [PATCH 0/4] Some minor printf improvements
Date: Sat, 21 Feb 2015 00:21:15 +0100 [thread overview]
Message-ID: <1424474479-25543-1-git-send-email-linux@rasmusvillemoes.dk> (raw)
While studying the kernel's printf internals in order to write the
kernel-specific format checking for smatch, I stumbled on a few things
one could do to shave an instruction here and there. Nothing
earth-shattering.
Rasmus Villemoes (4):
lib/vsprintf.c: Eliminate some branches
lib/vsprintf.c: Reduce stack use in number()
lib/vsprintf.c: Eliminate duplicate hex string array
lib/vsprintf.c: Another small hack
