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/init/bitfield2.C | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/g++.dg/init/bitfield2.C (limited to 'gcc/testsuite/g++.dg/init/bitfield2.C') diff --git a/gcc/testsuite/g++.dg/init/bitfield2.C b/gcc/testsuite/g++.dg/init/bitfield2.C new file mode 100644 index 000000000..e54b2e423 --- /dev/null +++ b/gcc/testsuite/g++.dg/init/bitfield2.C @@ -0,0 +1,33 @@ +// PR c++/13371 +// Bug: We were failing to properly protect the lhs on the line marked +// "here" from multiple evaluation. + +// { dg-do run } + +extern "C" int printf (const char *, ...); + +enum E { E1, E2 }; + +struct A +{ + E e : 8; + unsigned char c; +}; + +A ar[2]; + +int c; + +int f() +{ + ++c; + printf ("f()\n"); + return 0; +} + +int main() +{ + ar[0].c = 0xff; + ar[f()].e = E1; // here + return (c != 1 || ar[0].c != 0xff); +} -- cgit v1.2.3
