Description Trond Eivind Glomsrxd 2000-11-21 20:18:22 UTC
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.

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 17:39:15 UTC
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 12:57:52 UTC
This was fixed in gcc-2.96-101.
