Subject: Move the post-lsr simplify cfg pass after lowereh, so it can clean up after
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5e8d2dc19790b2262a27a67a1900ce187d661172;p=oota-llvm.git

Move the post-lsr simplify cfg pass after lowereh, so it can clean up after
eh lowering as well.
