Subject: Remove IND_LABEL_W and IND_LABEL_D
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=19f0eb86a45852274622348fa56d912d2261d55a;p=ack.git

Remove IND_LABEL_W and IND_LABEL_D

Because li32 always loads a label into a GPR, it is sufficient to
coerce LABEL to REG, then use IND_RC_W or IND_RC_D for indirection
through the label.
