Subject: Add VIEW_CONVERT_EXPR to operand_equal_p
Date: Wed, 14 Oct 2015 16:29:00 -0000 [thread overview]
Message-ID: <20151014162944.GE16672@kam.mff.cuni.cz> (raw)
Hi,
this patch adds VIEW_CONVERT_EXPR which is another code omitted in
operand_equal_p. During bootstrap there are about 1000 matches.
Bootstrapped/regtested x86_64-linux, OK?
