From: Andrew Pinski <apin...@marvell.com>
This patch series fixes PR tree-opt/102703 by
improving the code which will delete write only stores to also
delete the phi node (if it was a phi node) that was used to define
the write.
We need to some factoring out of the code to make it easier
to understand and less indention.
Andrew Pinski (4):
Add dump prints when execute_fixup_cfg removes a write only var store.
Remove outdated comment about execute_fixup_cfg
Factor out removal of write only stores from execute_fixup_cfg
Improve maybe_remove_writeonly_store to do a simple DCE for defining
statement
