Subject: gdb/iq2000: Use default gdbarch methods where possible
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf12844a68f3f4f267846a19df6a280f53e7ec5f;p=binutils-gdb.git

gdb/iq2000: Use default gdbarch methods where possible

Make use of the default gdbarch methods for gdbarch_dummy_id,
gdbarch_unwind_pc, and gdbarch_unwind_sp where possible.

I have not tested this change but, by inspecting the code, I believe
the default methods are equivalent to the code being deleted.

gdb/ChangeLog:

	* gdb/iq2000-tdep.c (iq2000_unwind_sp): Delete.
	(iq2000_unwind_pc): Delete.
	(iq2000_dummy_id): Delete.
	(iq2000_gdbarch_init): Don't register deleted functions with
	gdbarch.
