Subject: [PATCH 0/5] unssa improvements
Date: Thu, 1 Dec 2016 16:07:00 +0100 [thread overview]
Message-ID: <20161201150705.31590-1-luc.vanoostenryck@gmail.com> (raw)
This serie improves the out-of-SSA step by:
* simplify the conversion of the phi-nodes & phi-sources into copies
* eliminate some copies which are trivially not needed.
The elimination step is significant since on a small corpus which
produced 267 copies, after the patch only 165 remain.
Luc Van Oostenryck (5):
unssa: do not try to update liveness
unssa: simplify rewrite of OP_PHISOURCE
unssa: try to avoid some OP_PHI copies
unssa: eliminate trivial phisrc copies
unssa: update comment about the unneeded copies
