Constant vectors are currently spilled/loaded from memory often. This series
increases the number of costed patterns via a catch-all pattern and fixes a
variety of bugs I found along the way.
Patrick O'Neill (9):
RISC-V: Use encoded nelts when calling repeating_sequence_p
RISC-V: Fix vid const vector expander for non-npatterns size steps
RISC-V: Handle 0.0 floating point pattern costing to match
const_vector expander
RISC-V: Reorder insn cost match order to match corresponding expander
match order
RISC-V: Handle case when constant vector construction target rtx is
not a register
RISC-V: Emit costs for bool and stepped const vectors
RISC-V: Allow non-duplicate bool patterns in expand_const_vector
RISC-V: Move helper functions above expand_const_vector
RISC-V: Add vslide1up/down pattern to expand_const_vector
