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.
v2 Changelog:
* Landed patch 1/9 from v1 of this patchset.
* Add new valid_vec_immediate_p helper
* Reorder "Handle 0.0 floating point pattern ..." to use riscv-v.h.
* Fix build failure on patches 6-8 that was previously fixed by patch 9.
* Append RFC to series.
Patrick O'Neill (9):
RISC-V: Fix vid const vector expander for non-npatterns size steps
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: Handle 0.0 floating point pattern costing to match
const_vector expander
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
RISC-V: Add cost model asserts
