From: "rguenth at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/19580] [4.0/4.1/4.2/4.3 Regression] missed load/store motion Date: Wed, 23 Jan 2008 10:35:00 -0000 [thread overview] Message-ID: <20080123091207.29764.qmail@sourceware.org> (raw) In-Reply-To: <bug-19580-7958@http.gcc.gnu.org/bugzilla/> ------- Comment #37 from rguenth at gcc dot gnu dot org 2008-01-23 09:12 ------- The lim patch applies alias-oracle techniques to the loop invariant and store motion parts of tree-ssa-loop-im.c. I have a forward-port of Zdeneks patch to current trunk. Note that the alias-oracle patch for SCCVN does not fix this PR (it seems to be mostly ineffective for PRE, possibly PHI translation needs adjustments as well). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19580
