+ * config/pa/predicates.md (base14_operand): Except for BLKmode, QImode
+ and HImode, require all displacements to be an integer multiple of their
+ mode size.
+ * config/pa/pa.c (pa_legitimate_address_p): For REG+BASE addresses,
+ only allow QImode and HImode when reload is in progress and strict is
+ true. Likewise for symbolic addresses. Use base14_operand to check
+ displacements in REG+BASE addresses.
