Subject: i965/fs: Don't calculate_live_intervals() in opt_algebraic().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d010e70a07ab4a0b24aad8c9693a7f9c680d6164;p=mesa.git

i965/fs: Don't calculate_live_intervals() in opt_algebraic().

There's no point: opt_algebraic() doesn't use any liveness information.
