Hello,
2004-05-19 Jeff Law <law@redhat.com>
* tree-into-ssa.c (prepare_operand_for_rename): New argument
is_use.
If the operand is for a use, then strip away the SSA_NAME, do
not strip away the SSA_NAME for a set. Never call
release_ssa_name.
(mark_def_sites): Appropriately pass additional argument to
prepare_operand_for_rename. If a VDEF_RESULT is not an
SSA_NAME, then set the VDEF_RESULT to the VDEF_OP.
(set_def_block): Strip away any SSA_NAME to get to the real
underlying variable.
this patch causes a regression in the libjava test suite on ppclinux.
The famous Throw_2 test case times out.
I reverted the whole tree just before and after this patch. Before ok,
afterwards it hangs. I know, not much help, but I'm stuck atm.
Does anyone have an idea? What do you need to give me a help?
Thank in advance,
Andreas
