Subject: [Bug tree-optimization/26197] [4.2 regression] ICE in is_old_name, at tree-into-ssa.c:466
Date: Thu, 09 Feb 2006 15:10:00 -0000 [thread overview]
Message-ID: <20060209151013.14088.qmail@sourceware.org> (raw)
In-Reply-To: <bug-26197-1771@http.gcc.gnu.org/bugzilla/>
------- Comment #1 from pinskia at gcc dot gnu dot org 2006-02-09 15:10 -------
Confirmed. (there is a missed optimization here also which Richard G. and I am
looking at right now).
Anyways,
Before:
# p_247 = PHI <&D.2477.a0.x[0](2)>;
<L183>:;
# TMT.32_246 = V_MAY_DEF <TMT.32_255>;
*p_247 = 0B;
After:
# SFT.12 = V_MAY_DEF <SFT.12>;
# TMT.32_246 = V_MAY_DEF <TMT.32_255>;
D.2477.a0.x[0] = 0B;
We forgot to rename SFT.12.
