Subject: Get register contents by register_size instead of TYPE_LENGTH
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d8e07dda92366be0f6fc2e7128620d3dd53494e3;p=binutils-gdb.git

Get register contents by register_size instead of TYPE_LENGTH

We should use register_size to get register contents instead of
TYPE_LENGTH.

gdb:

2017-05-24  Yao Qi  <yao.qi@linaro.org>

	* i387-tdep.c (i387_register_to_value): Use register_size
	instead of TYPE_LENGTH.
	* m68k-tdep.c (m68k_register_to_value): Likewise.
