optimization/5768: sh codegen leaves stuff on stack

[rth@gcc.gnu.org]

Synopsis: sh codegen leaves stuff on stack

State-Changed-From-To: open->feedback
State-Changed-By: rth
State-Changed-When: Mon Mar 25 14:06:20 2002
State-Changed-Why:
    This appears to have been fixed for gcc 3.1.  Would you mind
    checking the prerelease snapshots to verify this for your
    real application as opposed to merely the test case?
    
    For the last test in this thread, I see r8 being restored
    in the delay slot of the jump, like so:
    
            jmp     @r4
            mov.l   @r15+,r8
