Hi,
In this new version I decided to scrap patch 3 from v2 and added a patch
that Ivan Klokov sent back in December [1]. In that patch Ivan was
already doing things that Richard suggested to be done in patch 3 of v2.
This is done in patch 5.
Patches 1 and 2 were suggestions from Richard that I'm adding as
cleanup. Patch 2 in particular helped to clean up quite a bit of code.
Patch 3 is a fix in GEN_VEXT_VSLIDEUP_VX() that I caught while doing
code inspection to assert that all helpers were setting env->vstart = 0
in the end.
Patch 4 is patch 2 from v2 without any changes.
Patches based on alistair/riscv-to-apply.next.
Changes from v2:
- patches 1 and 3 from v2 were dropped, patch 2 from v2 is now patch 4
- patch 1: new
- dirty vs state before stores
- patch 2: new
- remove redundant conditionals
- patch 3: new
- assign env->vstart = 0 in GEN_VEXT_VSLIDEUP_VX()
- patch 5: taken from [1] with the following changes:
- fixed conflicts with alistair/riscv-to-apply.next
- changed "finalize_rrv_inst" instances to "finalize_rvv_inst" to fix
trans_rvvk.c.inc build
- set_vstart_eq_zero() removed; finalize_rvv_inst() will do a direct
ctx->vstart_eq_zero = true instead;
- finalize_rvv_inst() is removed from the #ifdef block since it's now
relevant to linux-user
