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/macro3.c | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/macro3.c (limited to 'gcc/testsuite/gcc.dg/cpp/macro3.c') diff --git a/gcc/testsuite/gcc.dg/cpp/macro3.c b/gcc/testsuite/gcc.dg/cpp/macro3.c new file mode 100644 index 000000000..e6a5ffc1e --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/macro3.c @@ -0,0 +1,37 @@ +/* { dg-do run } */ +/* { dg-options "-std=c99" } */ + +/* First two tests sourced from a bug report of Thomas Pornin. + Varargs test source Jamie Lokier. + All adapted for the testsuite by Neil Booth, Oct 2000. */ + +/* Tests various macro abuse is correctly expanded. */ +static int d = 4; +#define c(x) d +#define d(x) c(2) + +#if 0 +/* This macro chain above sucks up the whole file once it starts, so + I've commented it out.
