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/avoidpaste1.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/avoidpaste1.c (limited to 'gcc/testsuite/gcc.dg/cpp/avoidpaste1.c') diff --git a/gcc/testsuite/gcc.dg/cpp/avoidpaste1.c b/gcc/testsuite/gcc.dg/cpp/avoidpaste1.c new file mode 100644 index 000000000..3591f9c08 --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/avoidpaste1.c @@ -0,0 +1,29 @@ +/* Copyright (C) 2001, 2003 Free Software Foundation, Inc. */ + +/* { dg-do preprocess } */ +/* { dg-options "-ansi" } */ + +/* This tests that we avoid accidental pasting only before and after + macros and arguments, and not when the tokens are already pasted + in the souce file (e.g. "::" in a C source file). + + Neil Booth, 28 Jan 2001. */ + +#define f(x) x +#define g +#define tricky 1.0e ## -1 + +/* This should preprocess as + +:: : : : : :^: 1.0e- 1 +: : : .. . 0 0 . + +It relies on the fact that even when preprocessing C we bother to separate +the colons of C++'s :: operator.
