read-md.h (fatal_at): Declare. 

gcc/
	* read-md.h (fatal_at): Declare.
	* read-md.c (fatal_at): New function.
	* genattrtab.c (insn_def, attr_desc, delay_desc): Use a file_location
	to record the source position.
	(check_attr_test): Take a file_location instead of a line number.
	Use fatal_at instead of fatal.
	(check_attr_value): Update after above changes, using "at"
	rather than "with_line" reporting functions.
	(convert_set_attr_alternative): Likewise.
	(gen_attr): Likewise.
	(check_defs): Likewise.  Don't assign to read_md_filename.
	(gen_insn): Update initialization after above changes.
	(gen_delay): Likewise.
	(write_insn_cases): Print the filename for a define_peephole.
	(gen_insn_reserv): Take a line number as argument and update
	the call to check_attr_test.
	(main): Pass a line number to gen_insn_reserv.
