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/template/const1.C | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/g++.dg/template/const1.C (limited to 'gcc/testsuite/g++.dg/template/const1.C') diff --git a/gcc/testsuite/g++.dg/template/const1.C b/gcc/testsuite/g++.dg/template/const1.C new file mode 100644 index 000000000..629c4d4a9 --- /dev/null +++ b/gcc/testsuite/g++.dg/template/const1.C @@ -0,0 +1,30 @@ +// PR c++/28385 +// instantiating op() with void()() was making the compiler think that 'fcn' +// was const, so it could eliminate the call. + +// { dg-do run } + +extern "C" void abort (void); + +int barcnt = 0; + +class Foo { + public: + template + void operator()(const T& fcn) { + fcn(); + } +}; + +void bar() { + barcnt++; +} + +int main() { + Foo myFoo; + myFoo(bar); + myFoo(&bar); + if (barcnt != 2) + abort (); + return 0; +} -- cgit v1.2.3
