Description Trond Eivind Glomsrxd 2000-11-21 15:18:22 EST

gcc 2.96-64 has problems compiling claswp.f on SPARC with -O2 (-O1 works fine):

[root@bart /]# g77 -c -O1 claswp.f
[root@bart /]# g77 -c -O2 claswp.f
claswp.f: In subroutine `claswp':
claswp.f:116: Internal compiler error in verify_local_live_at_start, at
flow.c:2729
Please submit a full bug report.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.
[root@bart /]#

claswp.f is part of LAPACK.

FORTRAN file which triggers a problem in gcc.

Comment 2 Bill Nottingham 2000-11-22 00:09:12 EST

FWIW, when I ran an ia64 compiler on a buggy machine, it
*always* ICEd at that exact point. Maybe our sparcs have the
same hardware bug? :)

Comment 3 Jakub Jelinek 2000-11-22 12:39:15 EST

No, I'm able to reproduce it on my SPARC and even in an ia32->SPARC cross
g77. It does not happen in current CVS nor on subreg-byte branch (cut
in September), so I'll have to track down which patch fixes this.

Comment 4 Jakub Jelinek 2001-11-28 07:57:52 EST

This was fixed in gcc-2.96-101.
