VAX: Correct issues with commented-out insns
Correct issues with commented-out insns, which fail to build if enabled:
.../gcc/config/vax/vax.md:503:1: repeated operand number 1
.../gcc/config/vax/vax.md:503:1: repeated operand number 2
and then when the issue with the repeated operands has been corrected:
.../gcc/config/vax/vax.md:107:1: destination operand 0 allows non-lvalue
.../gcc/config/vax/vax.md:503:1: destination operand 0 allows non-lvalue
.../gcc/config/vax/vax.md:503:1: destination operand 3 allows non-lvalue
.../gcc/config/vax/vax.md:744:1: destination operand 0 allows non-lvalue
Fix the RTL with the repeated operands and change the relevant output
operand predicates not to allow immediates.
Also emit MOVO rather than MOVH assembly instruction with the `movti'
insn so that the condition codes are set according to the integer rather
than floating-point interpretation of the datum moved, as expected with
the operation associated with the pattern.
Finally give `*amulsi4' a name, for easier reference here and elsewhere.
We may eventually want to have some of these insns enabled at `-Os'.
gcc/
* config/vax/vax.md (movti): Fix output predicate. Emit `movo'
rather than `movh'.
(divmoddisi4): Fix output predicates, correct RTL.
(*amulsi4): Name insn. Fix output predicate.
