Preparing to use shifts to eliminate redundant test/compare insns on H8
* config/h8300/h8300-protos.h (output_a_shift): Make first argument
an array of rtx rather than a pointer to rtx. Add code argument.
(compute_a_shift_length): Similarly.
* config/h8300/h8300.c (h8300_shift_costs): Adjust now that the
shift itself isn't an operand. Create dummy operand[0] to carry
a mode and pass a suitable rtx code to compute_a_shift_length.
(get_shift_alg): Adjust operand number of clobber in output templates.
(output_a_shift): Make first argument an array of rtx rather than
a pointer to rtx. Add code argument for the type of shift.
Adjust now that the shift itself is no longer an operand.
(compute_a_shift_length): Similarly.
* config/h8300/shiftrotate.md (shiftqi, shifthi, shiftsi): Use an
iterator rather than nshift_operator.
(shiftqi_noscratch, shifthi_noscratch, shiftsi_noscratch): Likewise.
(shiftqi_clobber_flags): Adjust to API changes in output_a_shift
and compute_a_shift_length.
(shiftqi_noscratch_clobber_flags): Likewise.
(shifthi_noscratch_clobber_flags): Likewise.
(shiftsi_noscratch_clobber_flags): Likewise.
