re PR target/70799 (STV pass does not convert DImode shifts)
PR target/70799
* config/i386/i386.c (dimode_scalar_to_vector_candidate_p)
<case ASHIFT, case LSHIFTRT>: Also consider variable shifts.
Check "XEXP (src, 1)" operand here.
<case PLUS, case MINUS, case IOR, case XOR, case AND>:
Check "XEXP (src, 1)" operand here.
(dimode_scalar_chain::make_vector_copies): Detect count register
of a shift instruction. Zero extend count register from QImode
to DImode to satisfy vector shift pattern count operand predicate.
Substitute vector shift count operand with a DImode copy.
(dimode_scalar_chain::convert_reg): Ditto, zero-extend from
vector register.
testsuite/ChangeLog:
PR target/70799
* gcc.target/i186/pr70799-4.c: New test.
