Subject: [Bug middle-end/39284] Computed gotos combined too aggressively
Date: Mon, 08 Jun 2009 20:56:00 -0000	[thread overview]
Message-ID: <20090608205545.2311.qmail@sourceware.org> (raw)
In-Reply-To: <bug-39284-13604@http.gcc.gnu.org/bugzilla/>



------- Comment #8 from hubicka at gcc dot gnu dot org  2009-06-08 20:55 -------
Hmm,
the conditional is bogus, there should not be !
but still after patching this we don't duplicate.  The reason is that the BB 71
(containing conditional jump) is reached via 2 BBs containing memory load.  I
guess it is result of crossjumping.

I will send patch fixing the conditional, but it makes little difference.
