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/spec35.C | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/g++.dg/template/spec35.C (limited to 'gcc/testsuite/g++.dg/template/spec35.C') diff --git a/gcc/testsuite/g++.dg/template/spec35.C b/gcc/testsuite/g++.dg/template/spec35.C new file mode 100644 index 000000000..709ece5dd --- /dev/null +++ b/gcc/testsuite/g++.dg/template/spec35.C @@ -0,0 +1,29 @@ +// PR c++/31923 +// C++ DR 605 -- "...the linkage of an explicit specialization must be that of +// the template." + +// { dg-require-weak "" } +// { dg-do compile { target i?86-*-* x86_64-*-* } } + +template +static void f1 (T) { } + +// { dg-final { scan-assembler-not ".glob(a|)l\[\t \]*_?_Z2f1IfEvT_" } } +template<> +void f1 (float) { } // Expected to have static linkage + +template +void f2 (T) { } + +// { dg-final { scan-assembler ".glob(a|)l\[\t \]*_?_Z2f2IfEvT_" } } +template<> +void f2 (float) { } // Expected to have global linkage + +void instantiator () +{ + // { dg-final { scan-assembler-not ".glob(a|)l\[\t \]*_?_Z2f1IiEvT_" } } + f1(0); // Expected to have static linkage + + // { dg-final { scan-assembler ".weak(_definition)?\[\t \]*_?_Z2f2IiEvT_" { target { ! { *-*-mingw* *-*-cygwin } } } } } + f2(0); // Expected to have weak global linkage +} -- cgit v1.2.3
