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/g++.dg/parse/expr3.C | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/g++.dg/parse/expr3.C (limited to 'gcc/testsuite/g++.dg/parse/expr3.C') diff --git a/gcc/testsuite/g++.dg/parse/expr3.C b/gcc/testsuite/g++.dg/parse/expr3.C new file mode 100644 index 000000000..95d332f41 --- /dev/null +++ b/gcc/testsuite/g++.dg/parse/expr3.C @@ -0,0 +1,32 @@ +/* { dg-do compile } */ +/* PR/18047 Test that operators have the right precedence. */ +/* by bonzini@gnu.org */ + +#define test(lower, higher, a, b, c, d) \ + test_(lower, higher, a, b, c, d, __LINE__) + +#define test_(lower, higher, a, b, c, d, line)\ + test__(lower, higher, a, b, c, d, line) + +/* The first declaration tests that the parentheses are added correctly + by the expression parser.
