This patch removes unused macros in dwarfout.c.
Ok to commit if bootstrap passes on i686-linux-gnu?
Andreas
2003-06-01 Andreas Jaeger <aj@suse.de>
* dwarfout.c: Remove USE_ORDERING_ATTRIBUTE,
DWARF_DECL_COORDINATES and DWARF_TIMESTAMPS dependend declarations.
(ordering_attribute): Removed.
(output_array_type_die): Remove USE_ORDERING_ATTRIBUTE dependend
code.
(src_coords_attribute): Removed.
(name_and_src_coords_attributes): Remove DWARF_DECL_COORDINATES usage.
(dwarfout_init): Remove DWARF_TIMESTAMPS usage.
* system.h: Poison USE_ORDERING_ATTRIBUTE, DWARF_DECL_COORDINATES
and DWARF_TIMESTAMPS.
