The problem is that -fomit-frame--pointer is not set in -O0. so the ways to fixing it would be 1) enforce -fomit-frame-pointer in the stack-usage test, so we have a deterministic result 2) change the machine description so that the frame pointer is not needed in -O0. Actually I don't foresee any problem with this, but should be tried on the trunk only and with a different patch. for the current issue I propose to fix the test for the SH with 1). what do you think Kaz ?
