Subject: [PATCH 17/18] gdb: or1k: Updates for compiler type checking
Date: Wed, 23 Nov 2016 22:11:00 -0000	[thread overview]
Message-ID: <1479939044-1341-18-git-send-email-shorne@gmail.com> (raw)
In-Reply-To: <1479939044-1341-1-git-send-email-shorne@gmail.com>

There are several new compiler type checking enabled
in latest build/toolchain.  Fix issues where void* cannot
be blindly cast to type* also issues with enum vs int.

gdb/ChangeLog:

	* or1k-tdep.c (or1k_fetch_instruction): dont pass status
	directly to memory_error as they are different types
	(or1k_pseudo_register_read): return proper typed REG_UNKNOWN
	(or1k_frame_cache): cast result to trad_frame_cache
	(or1k_gdbarch_init): init gdbarch_tdep with XNEW
