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/cpp0x/nullptr22.C | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/g++.dg/cpp0x/nullptr22.C (limited to 'gcc/testsuite/g++.dg/cpp0x/nullptr22.C') diff --git a/gcc/testsuite/g++.dg/cpp0x/nullptr22.C b/gcc/testsuite/g++.dg/cpp0x/nullptr22.C new file mode 100644 index 000000000..d800f9869 --- /dev/null +++ b/gcc/testsuite/g++.dg/cpp0x/nullptr22.C @@ -0,0 +1,20 @@ +// { dg-do compile } +// { dg-options "-std=c++0x -Wall -Wformat=2 -Wstrict-null-sentinel" } + +// Test various warnings + +void f1(const char*, ...) __attribute__((format(printf, 1, 2))); +void f2(const char*) __attribute__((nonnull)); +void f3(const char*, ...) __attribute__((sentinel)); + +void f() +{ + f1("%p", nullptr); + f2(nullptr); // { dg-warning "null argument where non-null required " } + f3("x", "y", __null); // { dg-warning "missing sentinel in function call" } + f3("x", "y", nullptr); + decltype(nullptr) mynull = 0; + f1("%p", mynull); + f2(mynull); // { dg-warning "null argument where non-null required " } + f3("x", "y", mynull); +} -- cgit v1.2.3
