Re: [ssaupdate] SSA form updating rewrite



	* Makefile.in (tree-update-ssa.o): Add.
	* lambda-code.c (perfect_nestify): Do not call mark_for_rewrite
	and unmark_all_for_rewrite.


This was done to avoid the phi result name being released as we redirect an edge and then move phi nodes from one block to another (if you mark them for rewrite, it won't release the name), as the comment says.

I don't see anything i nwhat you've done that would change this being necessary.
