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/skipping.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/skipping.c (limited to 'gcc/testsuite/gcc.dg/cpp/skipping.c') diff --git a/gcc/testsuite/gcc.dg/cpp/skipping.c b/gcc/testsuite/gcc.dg/cpp/skipping.c new file mode 100644 index 000000000..b8daa890b --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/skipping.c @@ -0,0 +1,25 @@ +/* Copyright (C) 2000 Free Software Foundation, Inc. */ + +/* { dg-do preprocess } */ + +/* Tests expansion of macros whilst skipping false conditionals. */ + +/* Source: Neil Booth, 29 Oct 2000. */ + +#define F() +#define TRUE 1 + +#if 0 +F( /* No diagnostic: don't even try to expand it. */ +#endif + +#if 0 +#elif TRUE /* Expand this, even though we were skipping. */ +#else +#error Macros not expanded in #elif +#endif + +/* Check we don't warn about bad identifiers when skipping. */ +#if 0 +#define foo __VA_ARGS__ /* { dg-bogus "warned about identifier" } */ +#endif -- cgit v1.2.3
