Subject: [PATCH] bsc#1239566 - add -[DU]_FORTIFY_SOURCE[=n] to DW_AT_producer
To: gcc-patches@gcc.gnu.org

The following makes sure to record -D_FORTIFY_SOURCE=n and
-U_FORTIFY_SOURCE in the DW_AT_producer debuginfo attribute when
present on the compiler command line.

	* opts.cc (gen_producer_string): Record -D and -U
	with _FORTIFY_SOURCE prefix.
