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/cpp/c90-empty-macro-args.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/c90-empty-macro-args.c (limited to 'gcc/testsuite/gcc.dg/cpp/c90-empty-macro-args.c') diff --git a/gcc/testsuite/gcc.dg/cpp/c90-empty-macro-args.c b/gcc/testsuite/gcc.dg/cpp/c90-empty-macro-args.c new file mode 100644 index 000000000..e90f8e6cb --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/c90-empty-macro-args.c @@ -0,0 +1,19 @@ +/* { dg-do compile } */ +/* { dg-options "-std=c89 -pedantic" } */ + +#define f(a,b) f2(a,,b) +#define f2(a,b,c) a; b; c; +#define f3(a) a + +#define g() p() + +void p(void) {} + + +void foo(void) +{ + f(p(),p()); /* { dg-warning "macro f2 argument 2: empty macro arguments are undefined" } */ + f2(p(),,p()); /* { dg-warning "macro f2 argument 2: empty macro arguments are undefined" } */ + f3(); /* { dg-warning "macro f3 argument 1: empty macro arguments are undefined" } */ + g(); +} -- cgit v1.2.3
