Subject: target/riscv/vector_helper.c: set vstart = 0 in GEN_VEXT_VSLIDEUP_VX()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d3646e31ce6d1e02e46e6eabdbc2e637c0cbece7;p=qemu.git

target/riscv/vector_helper.c: set vstart = 0 in GEN_VEXT_VSLIDEUP_VX()

The helper isn't setting env->vstart = 0 after its execution, as it is
expected from every vector instruction that completes successfully.
