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/dllimport3.C | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/dllimport3.C (limited to 'gcc/testsuite/g++.dg/ext/dllimport3.C') diff --git a/gcc/testsuite/g++.dg/ext/dllimport3.C b/gcc/testsuite/g++.dg/ext/dllimport3.C new file mode 100644 index 000000000..6538232f7 --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/dllimport3.C @@ -0,0 +1,24 @@ +// { dg-do compile { target i?86-*-cygwin* i?86-*-mingw* x86_64-*-mingw* } } + +// PR 10148 Dllimport attribute of object is overriden by later +// redefinition without attribute. + +struct Foo +{ + int a; +}; + + __attribute__((dllimport)) struct Foo f; + +void Bar(void) +{ + void* dummy = (void*) &f; +} + +struct Foo f; // { dg-warning "referenced with dll linkage" } + +// Dllimport'd symbols do not have a constant address, so following +// assignment would require static_initialization_and_destruction +// if attribute is retained. + +void* dummy = &f; -- cgit v1.2.3
