Janus Weil f0f67c96c3 re PR libfortran/36044 (user-requested backtrace) 
2012-12-20  Janus Weil  <janus@gcc.gnu.org>

	PR fortran/36044
	* gfortran.h (gfc_isym_id): Add GFC_ISYM_BACKTRACE.
	* intrinsic.c (add_subroutines): Add "backtrace".
	* intrinsic.texi (BACKTRACE): Document BACKTRACE intrinsic.


2012-12-20  Janus Weil  <janus@gcc.gnu.org>

	PR fortran/36044
	* gfortran.map: Add _gfortran_backtrace.
	* libgfortran.h: Rename 'show_backtrace' and export.
	* runtime/backtrace.c (show_backtrace): Rename to 'backtrace'.
	Don't show message. Close file descriptor. Export.
	* runtime/compile_options.c (backtrace_handler): Renamed
	'show_backtrace'. Move message outside.
	* runtime/error.c (sys_abort): Ditto.

(1) Symbols used only within the library,
(2) Symbols to be exported from the library,
(3) Symbols to be exported from the library, but
also used inside the library.
By telling the compiler about these different classifications we can
tightly control the interface seen by the user, and get better code
from the compiler at the same time.
One of the following should be used immediately after the declaration
of each symbol:
internal_proto Marks a symbol used only within the library,
and adds IPREFIX to the assembly-level symbol
name. The later is important for maintaining
the namespace partition for the static library.
export_proto Marks a symbol to be exported, and adds PREFIX
to the assembly-level symbol name.
export_proto_np Marks a symbol to be exported without adding PREFIX.
iexport_proto Marks a function to be exported, but with the
understanding that it can be used inside as well.
iexport_data_proto Similarly, marks a data symbol to be exported.
Unfortunately, some systems can't play the hidden
symbol renaming trick on data symbols, thanks to
the horribleness of COPY relocations.
If iexport_proto or iexport_data_proto is used, you must also use
iexport or iexport_data after the *definition* of the symbol. */
