Note you forgot to mention what options you used, -O1 was enough to reproduce this.
I can confirm this on 3.3.1 (20030714) and the mainline (20030718).

This did not occur in Hard Hat 2.0's gcc-2.97, nor in dodes' gcc-3.0.2,
so IMHO this is a regression. I'll submit a patch to add this test to
the testsuite. Thanks!

The patch seems simple enough for 3.3.2 (note I cannot approve anything).

Fix works for me in gcc-3.3.1 as released (haven't tried applying it to branch yet).

I've prepared a patch to add a testcase for this PR to the testsuite; see
http://www.kegel.com/crosstool/current/patches/gcc-3.3.1/pr11587-1-test.patch
I'll submit it to gcc-patches in a couple days if nobody squawks.
BTW, the fix for bug 11587 seemed to fix bug 11162 for me.

Subject: Re: [3.3 Regression] SH ICE in reload_cse_simplify_operand, postreload.c
The patch tests the wrong condition. A copy from T to a general purpose
register is unproblematic and cheap. The need for a secondary reload
arises on the contrary when the other class is not a general purpose register.
See how FPSCR_REGS is handled.

Proposed patch is wrong and the problem is fixed in 3.4.x.
Proper patch for 3.3.x is unlikely.

I was surprised and pleased to see that my testcase for this bug
passes if you apply SUGIOKA Toshinobu's backport of the fix for PR13260 to
gcc-3.3.3 (mis-archived as
http://www.m17n.org/linux-sh/ml/linux-sh/2003-02/msg00014.html)!
So those of you using gcc-3.3.3 might want to apply that patch.
In fact, maybe we should consider applying it to gcc-3.3.3 in cvs before release...
