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-label-1.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wunused-label-1.c (limited to 'gcc/testsuite/gcc.dg/Wunused-label-1.c') diff --git a/gcc/testsuite/gcc.dg/Wunused-label-1.c b/gcc/testsuite/gcc.dg/Wunused-label-1.c new file mode 100644 index 000000000..1840a8008 --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wunused-label-1.c @@ -0,0 +1,13 @@ +/* { dg-do compile } */ +/* { dg-options "-Wunused-label" } */ + +extern void f2 (); + +void +f1 () +{ + l1: f2 (); /* { dg-warning "not used" } */ + l2: __attribute__ ((unused)) f2 (); + l3: ; f2 (); /* { dg-warning "not used" } */ + l4: __attribute__ ((unused)) ; f2 (); +} -- cgit v1.2.3
