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/ext/instantiate1.C | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/instantiate1.C (limited to 'gcc/testsuite/g++.dg/ext/instantiate1.C') diff --git a/gcc/testsuite/g++.dg/ext/instantiate1.C b/gcc/testsuite/g++.dg/ext/instantiate1.C new file mode 100644 index 000000000..1d2a6200b --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/instantiate1.C @@ -0,0 +1,24 @@ +// Test that 'extern template' suppresses instantiations. +// { dg-do compile } +// { dg-options "" } + +template void f (T) { } +extern template void f (int); + +template struct A { + void f (); +}; +template void A::f () { } +extern template struct A; + +// { dg-final { scan-assembler-not "\n_?_Z1fIiEvT_(:|\n|\t)" } } +void test_f_int () { f(42); } + +// { dg-final { scan-assembler-not "\n_?_ZN1AIiE1fEv(:|\n|\t)" } } +void test_A_int_f () { A a; a.f (); } + +// { dg-final { scan-assembler "\n_?_Z1fIdEvT_(:|\n|\t)" } } +void test_f_double () { f (2.0); } + +// { dg-final { scan-assembler "\n_?_ZN1AIdE1fEv(:|\n|\t)" } } +void test_A_double_f () { A b; b.f (); } -- cgit v1.2.3
