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/g++.dg/warn/Wunused-label-1.C | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/Wunused-label-1.C (limited to 'gcc/testsuite/g++.dg/warn/Wunused-label-1.C') diff --git a/gcc/testsuite/g++.dg/warn/Wunused-label-1.C b/gcc/testsuite/g++.dg/warn/Wunused-label-1.C new file mode 100644 index 000000000..96f49b321 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/Wunused-label-1.C @@ -0,0 +1,28 @@ +// { dg-do compile } +// { dg-options "-Wunused-label" } + +extern void f9(); + +void +f1() +{ + l1: f9(); // { dg-warning "not used" } + l3: ; f9(); // { dg-warning "not used" } + l4: __attribute__ ((unused)) ; f9(); +} + +void +f2() +{ + label: __attribute ((unused)) ; +} + +void +f3() +{ + // The next line would be OK in C but is a syntax error in C++. + l2: __attribute__ ((unused)) f9(); // { dg-error "expected" } + // We still get an unused label warning--this is + // optional and can be removed if it ever changes. + // { dg-warning "not used" "expected" { target *-*-* } 24 } +} -- cgit v1.2.3
