From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/Wunused-function.c | 6 ++++++ 1 file changed, 6 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wunused-function.c (limited to 'gcc/testsuite/gcc.dg/Wunused-function.c') diff --git a/gcc/testsuite/gcc.dg/Wunused-function.c b/gcc/testsuite/gcc.dg/Wunused-function.c new file mode 100644 index 000000000..1c59c5003 --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wunused-function.c @@ -0,0 +1,6 @@ +/* PR c/4076 -Wunused doesn't warn about static function only called by itself. */ +/* { dg-do compile } */ +/* { dg-options "-Wunused-function" } */ + +static void foo (void) {} /* { dg-warning "'foo' defined but not used" } */ +static void bar (void) { bar (); } /* { dg-warning "'bar' defined but not used" } */ -- cgit v1.2.3
