Here is the stack RTL dump again. As you can see
(clobber (reg:SF 14 %st(6)))
should be
(clobber (reg:SF 8 %st(0)))
Should I worry about it? I think the bug is in move_for_stack_reg () in
reg-stack.c:
There is no need to worry about it for the egcs-1.0.3 release or the egcs-1.1.x
release. It would be nice to get this fixed in the development sources in
the long term, but for now it is perfectly harmless.
There is a general problem that reg-stack does not perform register
substitutions in clobbers. The fix will probably be involved, and would
not be safe for any pending release.
