 366         * config/pa/pa.md (decrement_and_branch_until_zero): Use `Q' constraint
 367         instead of `m' constraint.  Likewise for unnamed movb comparison
 368         patterns using reg_before_reload_operand predicate.
 369         * config/pa/predicates.md (reg_before_reload_operand): Tighten
 370         predicate to reject register index and LO_SUM DLT memory forms
 371         after reload.

 395
 396         Instrument bit field and unaligned accesses for TSAN.
 397         * sanitizer.def (BUILT_IN_TSAN_READ_RANGE): New built-in function.
