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.
