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-1.C | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/Wunused-1.C (limited to 'gcc/testsuite/g++.dg/warn/Wunused-1.C') diff --git a/gcc/testsuite/g++.dg/warn/Wunused-1.C b/gcc/testsuite/g++.dg/warn/Wunused-1.C new file mode 100644 index 000000000..60ceb4f07 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/Wunused-1.C @@ -0,0 +1,15 @@ +// Test whether -Wunused handles empty classes the same as non-empty. +// { dg-do compile } +// { dg-options "-Wunused" } + +struct A {}; +struct B { char c; }; + +void foo () +{ + struct A a0, a1; + struct B b0, b1 = { 25 }; + + a0 = a1; // { dg-bogus "value computed is not used" } + b0 = b1; +} -- cgit v1.2.3
