From fb7d0b3cefb80a105f7fd26bbc62e0cbf9192822 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Mon, 24 Jan 2011 11:13:04 -0500 Subject: perf tool: Fix gcc 4.6.0 issues GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf due to the -Werror=unused-but-set-variable flag. I've gone through and annotated some of the assignments that had side effects (ie: return value from a function) with the __used annotation, and in some cases, just removed unused code. In a few cases, we were assigning something useful, but not using it in later parts of the function. kyle@dreadnought:~/src% gcc --version gcc (GCC) 4.6.0 20110122 (Red Hat 4.6.0-0.3) Cc: Ingo Molnar LKML-Reference: <20110124161304.GK27353@bombadil.infradead.org> Signed-off-by: Kyle McMartin [ committer note: Fixed up the annotation fixes, as that code moved recently ] Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/annotate.c | 3 --- 1 file changed, 3 deletions(-) (limited to 'tools/perf/util/annotate.c') diff --git a/tools/perf/util/annotate.c b/tools/perf/util/annotate.c index 297337649c21..1012841835a3 100644 --- a/tools/perf/util/annotate.c +++ b/tools/perf/util/annotate.c @@ -236,7 +236,6 @@ int symbol__annotate(struct symbol *sym, struct map *map, char command[PATH_MAX * 2]; FILE *file; int err = 0; - u64 len; char symfs_filename[PATH_MAX]; if (filename) { @@ -281,8 +280,6 @@ fallback: filename, sym->name, map->unmap_ip(map, sym->start), map->unmap_ip(map, sym->end)); - len = sym->end - sym->start; - pr_debug("annotating [%p] %30s : [%p] %30s\n", dso, dso->long_name, sym, sym->name); -- cgit v1.2.3
