Hi,
I had this patch sitting in my tree for a while, but somehow forgot to commit it.
The issue here is that edge redirection affects vops and thus imply need for
SSA update in some cases.

Bootstrapped/regtested x86_64-linux, will commit it shortly.
	PR middle-end/48836
	* ipa-inline-transform.c: Include tree-pass.h
	(inline_transform): Set TODO_update_ssa_only_virtuals.
	* Makefile.in (ipa-inline-transform.o): Add tree-pass.h.
