Subject: i965: Assert that SYSTEM_VALUE_VERTEX_ID gets lowered
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b70616f3e7834386f96498d9a99f2ad11b292b5b;p=mesa.git

i965: Assert that SYSTEM_VALUE_VERTEX_ID gets lowered

fs_visitor::emit_vs_system_value() looks like it's trying to handle
SYSTEM_VALUE_VERTEX_ID, but we should never see that value in the
backend.
