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/gcc.dg/ordered-comparison-4.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/ordered-comparison-4.c (limited to 'gcc/testsuite/gcc.dg/ordered-comparison-4.c') diff --git a/gcc/testsuite/gcc.dg/ordered-comparison-4.c b/gcc/testsuite/gcc.dg/ordered-comparison-4.c new file mode 100644 index 000000000..ebe9eddf3 --- /dev/null +++ b/gcc/testsuite/gcc.dg/ordered-comparison-4.c @@ -0,0 +1,21 @@ +/* Test warning for ordered comparison pointer with null pointer constant. */ +/* Test with -Wextra. */ +/* { dg-do compile } */ +/* { dg-options "-Wextra" } */ +extern void z(); +void *p; + +void f() { + if (z >= 0) /* { dg-warning "ordered comparison of pointer with" } */ + z(); + if (0 >= z) /* { dg-warning "ordered comparison of pointer with" } */ + z(); + if (p >= (void*)0) /* { dg-warning "ordered comparison of pointer with null pointer" } */ + z(); + if ((void*)0 >= p) /* { dg-warning "ordered comparison of pointer with null pointer" } */ + z(); + if (z >= (void*)0) /* { dg-warning "distinct pointer types lacks a cast" } */ + z(); + if ((void*)0 >=z) /* { dg-warning "distinct pointer types lacks a cast" } */ + z(); +} -- cgit v1.2.3
