Subject: [PATCH] target/riscv/vector_helper.c: set vstart = 0 in
|
||
|
|
GEN_VEXT_VSLIDEUP_VX()
|
||
|
|
|
||
|
|
cherry-pick from d3646e31ce6d1e02e46e6eabdbc2e637c0cbece7
|
||
|
|
|
||
|
|
The helper isn't setting env->vstart = 0 after its execution, as it is
|
||
|
|
expected from every vector instruction that completes successfully.
