Fix addvdi3 and subvdi3 patterns
While most PA 2.0 instructions support both 32 and 64-bit traps
and conditions, the addi and subi instructions only support 32-bit
traps and conditions. Thus, we need to force immediate operands
to register operands on the 64-bit target and use the add/sub
instructions which can trap on 64-bit signed overflow.
2022-11-30 John David Anglin <dang...@gcc.gnu.org>
gcc/ChangeLog:
* config/pa/pa.md (addvdi3): Force operand 2 to a register.
Remove "addi,tsv,*" instruction from unamed pattern.
(subvdi3): Force operand 1 to a register.
Remove "subi,tsv" instruction from from unamed pattern.
