[PATCH for-9.0 v14 0/8] riscv: set vstart_eq_zero on vector insns

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

Hi,

In this version we're fixing a redundant check in the vmvr_v helper that
was pointed out by in v13.

To make this change easier patches 3 and 4 switched places. A trivial
change was made in patch 4 that don't warrant another review.

We're missing acks in patch 3 only.  

Series based on master. 

Changes from v13:
- patches 3 and 4: switched places
- patch 3:
  - fixed commit msg: from
    "(...) now sure that vstart is being clearer"
    to
    "(...) now sure that vstart is being cleared"
- patch 4:
  - do not check for vstart >= vl (i.e. add VSTART_CHECK_EARLY_EXIT())
    in the 'vmvr_v' helper

Daniel Henrique Barboza (7):
  target/riscv/vector_helper.c: set vstart = 0 in GEN_VEXT_VSLIDEUP_VX()
  trans_rvv.c.inc: set vstart = 0 in int scalar move insns
  target/riscv: always clear vstart in whole vec move insns
  target/riscv/vector_helpers: do early exit when vstart >= vl
  target/riscv: remove 'over' brconds from vector trans
  trans_rvv.c.inc: remove redundant mark_vs_dirty() calls
  target/riscv/vector_helper.c: optimize loops in ldst helpers

Ivan Klokov (1):
  target/riscv: enable 'vstart_eq_zero' in the end of insns
