PR target/56214
* config/pa/predicates.md (base14_operand): Except for BLKmode, QImode and HImode, require all displacements to be an integer multiple of the 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@196122 138bc75d-0d04-0410-961f-82ee72b054a4
