[Bug debug/43077] VTA issues caused by SSA expand

[matz at gcc dot gnu dot org]

------- Comment #3 from matz at gcc dot gnu dot org  2010-02-18 16:12 -------
At least varb isn't printed in fn3, because dse2 (after prologue_epilogue)
makes the expressions in the debug_insn be (clobber 0).  Presumably because
frame elimination rewrites the address-takings, but not the debug instructions,
hence it thinks they are uninited stores, as they still refer
to the frame pointer, not the stack pointer.
