Subject: Remove MAX_REGISTER_SIZE from target.c
X-Git-Tag: gdb-8.0-release~289
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed771251e16c8c66cbdd03738135e76caef6937e;p=external%2Fbinutils.git

Remove MAX_REGISTER_SIZE from target.c

gdb/
	* regcache.c (regcache_debug_print_register): New function.
	* regcache.h (regcache_debug_print_register): New declaration.
	* target.c (debug_print_register): Remove.
	(target_fetch_registers): Call regcache_debug_print_register.
	(target_store_registers): Likewise.
