Subject: 	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.
