Subject: i965: Start program_string_id from 1, not 0.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4ec3f0f4b98040edf21e395c9137dd99b0febdbf;p=mesa.git

i965: Start program_string_id from 1, not 0.

This way, I can safely use brw_tcs_prog_key::program_string_id == 0
to mean "not filled out because no program exists", which avoids the
need for adding an extra boolean to that struct.
