From: "dann at godzilla dot ics dot uci dot edu" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug optimization/13875] [tree-ssa] missed jump thread optimization on the tree-level Date: Tue, 20 Apr 2004 16:40:00 -0000 [thread overview] Message-ID: <20040420162503.13934.qmail@sources.redhat.com> (raw) In-Reply-To: <20040127051055.13875.dann@godzilla.ics.uci.edu> ------- Additional Comments From dann at godzilla dot ics dot uci dot edu 2004-04-20 16:25 ------- The non-optimal code at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13875#c14 seems to be caused by the way the fron-end handles bools, specifically all bools are cast to int before being used in an "if" and the optimizers are not able to remove these casts. (see PR15017, comment #5) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13875
