Is this PR fixed?  Or does it need some follow-up work?

Log message:

Fix PR tree-optimization/24287
* tree-dfa.c (dump_variable): Print reasons for call clobbering.
* tree-flow.h (struct ptr_info_def): Add escape mask to pointer.
(ESCAPE_TRANSITIVE): Removed.
(ESCAPE_TO_PURE_CONST): New.
(ESCAPE_IS_PARM): New.
(ESCAPE_UNKNOWN): New.
* tree-ssa-alias.c (set_initial_properties): Incoming pointers are
value escaping.
Pointers that point to anything are not.
Use pointer escape mask.
(is_escape_site): Use ESCAPE_TO_PURE_CONST.
* tree-ssa-operands.c (add_call_clobber_ops): Clean up a bit.
Things that *only* escape to pure/const functions are only read by
pure/const functions, and are not clobbered by the non-pure/const
functions.
(add_call_read_ops): Cleanup.
* tree-ssa-structalias.c (update_alias_info): Use pi-escape_mask,
not v_ann.

Actually, it's not related at all.
This is just a bug.
