Janne Blomqvist 1ff101ff12 PR 46686 Implement backtrace with _Unwind_Backtrace from libgcc.
2011-11-09  Janne Blomqvist  <jb@gcc.gnu.org>

	PR fortran/46686
	* configure.ac: Don't check execinfo.h, backtrace,
	backtrace_symbols_fd. Check execve instead of execvp. Call
	GCC_CHECK_UNWIND_GETIPINFO.
	* runtime/backtrace.c: Don't include unused headers, include
	limits.h and unwind.h.
	(CAN_FORK): Check execve instead of execvp.
	(GLIBC_BACKTRACE): Remove.
	(bt_header): Conform to gdb backtrace format.
	(struct bt_state): New struct.
	(trace_function): New function.
	(show_backtrace): Use _Unwind_Backtrace from libgcc instead of
	glibc backtrace functions.
	* Makefile.in: Regenerated.
	* aclocal.m4: Regenerated.
	* config.h.in: Regenerated.
	* configure: Regenerated.

README

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.
