[PATCH v8 04/10] target/riscv/vector_helper.c: update tail with vext_set_tail_elems_1s() |
|
Date: |
Fri, 8 Mar 2024 18:53:44 -0300 |
Change all code that updates tail elems to use vext_set_tail_elems_1s()
instead of vext_set_elems_1s().
Setting 'env->vstart=0' needs to be the very last thing a helper does
because env->vstart is being checked by vext_set_tail_elems_1s().
A side effect of this change is that a lot of 'vta' local variables got
unused. The reason is that 'vta' was being fetched to be used with
vext_set_elems_1s() but vext_set_tail_elems_1s() doesn't use it - 'vta' is
retrieve inside the helper using 'desc'.
