re PR target/56214 (FAIL: gcc.c-torture/execute/20050121-1.c compilation, ICE)
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.
