Actually, what I want is to handle VAR_DECL correctly, and your original
suggestion of using may_be_aliased() fits the bill. The other calls to
ptr_deref_may_alias_global_p() were fine because we have an SSA_NAME.
We're now down to a one-liner :).
How about this? All TM memory optimization tests fixed, and no regressions.
Ok. Note that may_be_aliased (x) is also true if x is an automatic variable
that has its address taken. You can use is_global_var (x) instead if you
only want to test for "global memory".
Richard.
is_global_var is fine. Thanks.
Committed.
