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 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.
