------- Comment #3 from dorit at gcc dot gnu dot org 2007-11-06 18:11 -------
I don't think these are related to PR33680. Sounds like we may be generating a
stmt with a cond_expr at the rhs. The data-reference analysis results in:
base_address: &blocks
offset from base address: k_4(D) == 0 ? 8 : 0
constant offset from base address: 0
step: 1
aligned to: 8
base_object: blocks[0][0]
symbol tag: blocks
(Note the cond_expr used to represent the offset).
We probably need to call the gimplifier (if we don't already) and also apply
Zdenek's patch that allows gimplifying rhs cond_exprs -
