Subject: i965: Generalize brw_vec4_upload_binding_table() beyond vec4 stages.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=72340839cae5db8630256f48868d8ce4a526a687;p=mesa.git

i965: Generalize brw_vec4_upload_binding_table() beyond vec4 stages.

Instead of passing in a brw_vec4_prog_data structure, we can simply
pass the one field it needs: the number of entries in the binding table.

We also need to pass in the shader time surface index rather than
hardcoding SURF_INDEX_VEC4_SHADER_TIME.

Since the resulting function is stage-agnostic, this patch removes
"vec4_" from the name.
