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++.old-deja/g++.other/loop1.C | 31 ++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.other/loop1.C (limited to 'gcc/testsuite/g++.old-deja/g++.other/loop1.C') diff --git a/gcc/testsuite/g++.old-deja/g++.other/loop1.C b/gcc/testsuite/g++.old-deja/g++.other/loop1.C new file mode 100644 index 000000000..168734c54 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.other/loop1.C @@ -0,0 +1,31 @@ +// { dg-do run } +// { dg-options "-O2" } +// Test for bad loop optimization of goto fixups. + +typedef bool (*ftype) (); + +int c, d; +struct A { + A() { ++c; } + A(const A&) { ++c; } + ~A() { ++d; } +}; + +void f (ftype func) +{ + A a; + do { + if ((*func)()) return; + } while (true); +} + +bool test () +{ + return true; +} + +main () +{ + f (test); + return (c != d); +} -- cgit v1.2.3
