Subject: intel/compiler: Pass single backend_shader argument to the fs_live_variables constructor
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d0433971f958be7d38cb96bfe226fbabdd7998e7;p=mesa.git

intel/compiler: Pass single backend_shader argument to the fs_live_variables constructor

This removes the dependency of fs_live_variables on fs_visitor.  The
IR analysis framework requires the analysis result to be constructible
with a single argument -- The second argument was redundant anyway.
