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/opt/cfg2.C | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/cfg2.C (limited to 'gcc/testsuite/g++.dg/opt/cfg2.C') diff --git a/gcc/testsuite/g++.dg/opt/cfg2.C b/gcc/testsuite/g++.dg/opt/cfg2.C new file mode 100644 index 000000000..229f4bc3a --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/cfg2.C @@ -0,0 +1,38 @@ +// PR optimization/12215 +// Origin: +// Reduced testcase by Wolfgang Bangerth + +// This used to fail because the CSE pass destroyed the CFG in presence +// of trapping loads, which led to the deletion of basic blocks. + +// { dg-do compile } +// { dg-options "-O2 -fno-gcse -fnon-call-exceptions" } + + +struct B { + ~B() throw() {} +}; + +struct X { + X(const char*, const B&); + ~X() {} +}; + +bool m(); +void f(int &i, float &arg0); + +void g (const char **argv) { + float val; + int i = 1; + + try { + while ( i < 1 ) + { + X arg(argv[i], B()); + if (m()) + throw(0); + + f(i, val); + } + } catch (...) {} +} -- cgit v1.2.3
