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/skip-1.C | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/skip-1.C (limited to 'gcc/testsuite/g++.dg/warn/skip-1.C') diff --git a/gcc/testsuite/g++.dg/warn/skip-1.C b/gcc/testsuite/g++.dg/warn/skip-1.C new file mode 100644 index 000000000..027c405d4 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/skip-1.C @@ -0,0 +1,17 @@ +// { dg-do compile } +// { dg-options "-Wall" } + +// Check that we don't warn about code that will not be executed. +extern int f2(int); +void +f1(int i) +{ + f2(1 == 1 ? 0 : f2(i >> -10)); + f2(1 == 1 ? 0 : f2(i >> 128)); + f2(1 == 1 ? 0 : f2(i << -10)); + f2(1 == 1 ? 0 : f2(1 << 128)); + f2(1 != 1 ? f2(i >> -10) : 0); + f2(1 != 1 ? f2(i >> 128) : 0); + f2(1 != 1 ? f2(i << -10) : 0); + f2(1 != 1 ? f2(1 << 128) : 0); +} -- cgit v1.2.3
