Subject: 	* arm-tdep.c (push_stack_item): 'contents' now const.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8c6363cf5c34e8728b3ad010a1611de234d6ed9d;p=binutils-gdb.git

	* arm-tdep.c (push_stack_item): 'contents' now const.
	(arm_push_dummy_call): Make 'val' const.  Use value_contents, not
	value_contents_writeable.  Introduce new temporary.
