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/pmf5.C | 39 +++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.other/pmf5.C (limited to 'gcc/testsuite/g++.old-deja/g++.other/pmf5.C') diff --git a/gcc/testsuite/g++.old-deja/g++.other/pmf5.C b/gcc/testsuite/g++.old-deja/g++.other/pmf5.C new file mode 100644 index 000000000..73fcedae0 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.other/pmf5.C @@ -0,0 +1,39 @@ +// { dg-do run } +// Bug: g++ expanded b->member() multiple times, causing the optimizer to +// decide that things weren't related and optimize 'die' into an infinite +// loop. + +struct A { + virtual ~A() { } + void f (bool) { } +}; + +typedef void (A::*pmf_void)(); +typedef void (A::*pmf_bool)(bool); + +struct B { + ~B() {} + pmf_void member() const { return mbr; } + pmf_void mbr; +}; + +A *a; +B *b; + +void die (bool param) { + pmf_bool pmf = (pmf_bool)(b->member()); + (a->*pmf)(param); +} + +int main () +{ + A a2; + B b2; + + b2.mbr = reinterpret_cast(&A::f); + + a = &a2; + b = &b2; + + die (true); +} -- cgit v1.2.3
