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/cmdlne-C.c | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/cmdlne-C.c (limited to 'gcc/testsuite/gcc.dg/cpp/cmdlne-C.c') diff --git a/gcc/testsuite/gcc.dg/cpp/cmdlne-C.c b/gcc/testsuite/gcc.dg/cpp/cmdlne-C.c new file mode 100644 index 000000000..2dafec253 --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/cmdlne-C.c @@ -0,0 +1,37 @@ +/* Copyright (C) 2000 Free Software Foundation, Inc. */ + +/* { dg-do preprocess } */ +/* { dg-options -C } */ + +/* Test -C doesn't fail with #define. #define is the tricky case, + being the only directive that remembers its comments. + + -C treats comments as tokens in their own right, so e.g. comment at + the beginning of a directive turns it into a non-directive. */ + +#define simple no comments + +#define/**/obj_like/**/(some)/**/thing/**/ +#define fun_like(/**/x/**/,/**/y/**/)/**/ +/**/#define not_a_macro + +#if !defined simple || !defined obj_like || !defined fun_like +#error Missed some macros with -C +#endif + +#ifdef not_a_macro +#error not_a_macro is! +#endif + +/* Check obj_like doesn't expect arguments, and fun_like does. */ +obj_like +fun_like (foo, bar) + +/* Check OK to redefine fun_like without comments in the params. */ +#define fun_like(x, y)/**/ + +/* Check comments in macros in directives are OK. */ +#define ZERO 0 /* A trailing comment. */ + +#if ZERO +#endif -- cgit v1.2.3
