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/trace-event-parse.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tools/perf/util/trace-event-parse.c') diff --git a/tools/perf/util/trace-event-parse.c b/tools/perf/util/trace-event-parse.c index 73a02223c629..d8e622dd738a 100644 --- a/tools/perf/util/trace-event-parse.c +++ b/tools/perf/util/trace-event-parse.c @@ -153,7 +153,7 @@ void parse_proc_kallsyms(char *file, unsigned int size __unused) char *next = NULL; char *addr_str; char ch; - int ret; + int ret __used; int i; line = strtok_r(file, "\n", &next); -- cgit v1.2.3
