Subject: [Bug tree-optimization/26524] [4.1 Regression] ICE when compiling with -ffast-math and -O3 clatm5.f (lapack)
Date: Wed, 01 Mar 2006 23:24:00 -0000 [thread overview]
Message-ID: <20060301232423.1955.qmail@sourceware.org> (raw)
In-Reply-To: <bug-26524-11356@http.gcc.gnu.org/bugzilla/>
------- Comment #4 from pinskia at gcc dot gnu dot org 2006-03-01 23:24 -------
Reduced testcase:
SUBROUTINE CLATM5( PRTYPE, M, N, A, LDA, B, LDB, C, LDC, D, LDD,
$ E, LDE, F, LDF, R, LDR, L, LDL, ALPHA, QBLCKA,
$ QBLCKB )
COMPLEX A( LDA, * ), B( LDB, * ), C( LDC, * ),
$ L( LDL, * ), R( LDR, * )
COMPLEX IMEPS, REEPS
DO 240 I = 1, M
IF( MOD( I, 2 ).NE.0 .AND. I.LT.M ) THEN
A( I, I-1 ) = -IMEPS*2
END IF
240 CONTINUE
END
----
The ICE is scev, I have not looked why yet and what fixed it either on the
mainline.
