Recent improvements to null address warnings notice that for targets that do not support HAVE_ELF_STYLE_WEAKREF the dummy stub implementation of __cxa_get_globals() means that the address can never be null. Fixed by removing the test for such targets. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> libitm/ChangeLog: * eh_cpp.cc (GTM::gtm_thread::init_cpp_exceptions): If the target does not support HAVE_ELF_STYLE_WEAKREF then do not try to test the __cxa_get_globals against NULL.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
