Summary: TREE_ADDRESSABLE overloading issues
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: middle-end
AssignedTo: [email protected]
ReportedBy: [email protected]
/* Do not change TREE_ADDRESSABLE if we need to preserve var as
a non-register. Otherwise we are confused and forget to
add virtual operands for it. */
&& (!is_gimple_reg_type (TREE_TYPE (var))
|| !bitmap_bit_p (not_reg_needs, DECL_UID (var))))
is causing alias analysis issues. We overload "address-taken" and
"lives-in-memory" with a single flag. Also causes issues like PR48335.
We should finally split this flag.
