From: Junio C Hamano Date: Fri, 27 Jan 2012 19:58:56 +0000 (-0800) Subject: vcs-svn/svndiff.c: squelch false "unused" warning from gcc X-Git-Tag: v1.7.10-rc0~118^2~3 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=58ebd9865d2bb9d42842fbac5a1c4eae49e92859;p=git.git vcs-svn/svndiff.c: squelch false "unused" warning from gcc Curiously, pre_len given to read_length() does not trigger the same warning even though the code structure is the same. Most likely this is because read_offset() is used only once and inlining it will make gcc realize that it has a chance to do more flow analysis. Alas, the analysis is flawed, so it does not help X-<.
