[PATCH] Add FRE pass to the early optimization pipeline
- From: Richard Guenther <rguenther at suse dot de>
- To: gcc-patches at gcc dot gnu dot org
- Date: Wed, 23 Mar 2011 15:17:47 +0100 (CET)
- Subject: [PATCH] Add FRE pass to the early optimization pipeline
For quite some releases we'd wanted some (memory) CSE optimization
during early opts. Currently we rely heavily on SRA which doesn't
always fulfill the "make code only smaller" promises which is
what early opts should do to improve precision of function size
estimates and to improve abstraction removal by early inlining.
Thus, this patch finally adds an early FRE pass at a suitable place.
The patch was sitting on pretty-ipa branch for some while now
and there were no noticeable issues with it there.
The patch disables FRE for the matrix-reorg testsuite - the
matrix reorg implementation is incredibly fragile with respect
to IL matching. It also isn't useful anymore as it relies on
-fwhole-program but isn't prepared to work together with LTO,
so it at most works on single translation-unit units. There is
no sign of anyone maintaining this code, but eventual removal
similar to struct-reorg should be handled separately from this patch.
Bootstrapped and tested on x86_64-unknown-linux-gnu (with the stdarg
patch applied).
Richard.
