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/19921210-1.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/19921210-1.c (limited to 'gcc/testsuite/gcc.dg/cpp/19921210-1.c') diff --git a/gcc/testsuite/gcc.dg/cpp/19921210-1.c b/gcc/testsuite/gcc.dg/cpp/19921210-1.c new file mode 100644 index 000000000..32d2a816e --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/19921210-1.c @@ -0,0 +1,13 @@ +/* Test for proper disabling of macros within their own expansions. */ +/* { dg-do compile } */ + +/* The following is a trick to evaluate a complex boolean expression + at compile time, inspired by autoconf 2.13's sizeof-detection. */ + +enum { a = 4, f = 3 }; + +#define a1(y) (y+2) +#define a2(y) a1(y)+1 +#define f a+f + +char array[(a2(f)) == 10 ? 1 : -1]; -- cgit v1.2.3
