Confirmed. Compiles fine on mainline though.

SH is not a primary target; postponing until GCC 3.4.2.

Hi,

Workaround : 
Use option -fno-cse-follow-jumps along with -O2 to get rid of ICE.
Tested on GCC 3.4.2 snapshot dated 13 Aug 2004.

I fail to see why an ICE on a non-primary target is critical.  Plus there is a
workaround too.

Because our policies say so. Look into http://gcc.gnu.org/managament.html. To 
tell the truth, the fact that it's a secondary platform should lower its 
priority, not its severity.

This bug doesn't pass the "to affect a significant fraction of users" test.

Removing target milestone; SH is not a primary or secondary target.
