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/expr/lval2.C | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/g++.dg/expr/lval2.C (limited to 'gcc/testsuite/g++.dg/expr/lval2.C') diff --git a/gcc/testsuite/g++.dg/expr/lval2.C b/gcc/testsuite/g++.dg/expr/lval2.C new file mode 100644 index 000000000..5d062f1c6 --- /dev/null +++ b/gcc/testsuite/g++.dg/expr/lval2.C @@ -0,0 +1,27 @@ +// PR c++/19199 + +// { dg-do run } + +// We used to turn the COND_EXPR lvalue into a MIN_EXPR rvalue, and +// then return a reference to a temporary in qMin. + +#include + +enum Foo { A, B }; + +template T &qMin(T &a, T &b) +{ + return a < b ? a : b; +} + +int main (int, char **) +{ + Foo f = A; + Foo g = B; + Foo &h = qMin(f, g); + assert (&h == &f || &h == &g); + const Foo &i = qMin((const Foo&)f, (const Foo&)g); + assert (&i == &f || &i == &g); + return 0; +} + -- cgit v1.2.3
