Subject: var-tracking.c (add_uses): Take an rtx rather than an rtx *.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3b4459f903c6da3b6c6e867bf1c62d6471ba5702;p=gcc.git

var-tracking.c (add_uses): Take an rtx rather than an rtx *.

gcc/
	* var-tracking.c (add_uses): Take an rtx rather than an rtx *.
	Give real type of data parameter.  Remove return value.
	(add_uses_1): Use FOR_EACH_SUBRTX_VAR rather than for_each_rtx
	to iterate over subrtxes.
