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/nonnull1.C | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/nonnull1.C (limited to 'gcc/testsuite/g++.dg/warn/nonnull1.C') diff --git a/gcc/testsuite/g++.dg/warn/nonnull1.C b/gcc/testsuite/g++.dg/warn/nonnull1.C new file mode 100644 index 000000000..46de7e931 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/nonnull1.C @@ -0,0 +1,16 @@ +// Test that "nonnull" attribute works for C++. +// Origin: Joseph Myers +// { dg-do compile } +// { dg-options "-Wall" } + +// The "nonnull" attribute is thoroughly tested for C, so here we +// simply test that it works at all, as at one point the relevant +// checking code was only called for C. + +extern void f (char *) __attribute__((nonnull)); + +void +g () +{ + f (0); // { dg-warning "null" "null argument" } +} -- cgit v1.2.3
