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/tree-ssa/pr22488.C | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr22488.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr22488.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr22488.C b/gcc/testsuite/g++.dg/tree-ssa/pr22488.C new file mode 100644 index 000000000..9063b067a --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr22488.C @@ -0,0 +1,33 @@ +// PR tree-optimization/22488 +// This testcase is really a C++ FE bug in represnting virtual inheritance +// It gives the appearance to the middle end that the fields exist twice +// which resulted in a very confused structure analyzer +// { dg-do compile } +// { dg-options "-O" } +struct X +{ + int i0, i1; + char c; +}; + +struct A +{ + int i; + char c0, c1; + + virtual ~A(); +}; + +struct B : virtual A {}; + +struct C : B +{ + X x; + + void bar(X y) { x = y; } +}; + +void foo() +{ + C().bar(X()); +} -- cgit v1.2.3
