Ian Romanick 3a1fdca5ad intel/vec4: Try to emit immediate sources for MOV ... Per the comment in vec4_visitor::nir_emit_load_const, further improvement is possible in this area. That case would be more complicated as I think we'd want to check that all users of the nir_load_const_instr result intended to use the value as float. No shader-db changes on any Gen8+ platform as these platforms do not use the vec4 backend. v2: Massive rebase on eeebeb211f ("intel/vec4: Try emitting non-scalar immediates"). This commit is about twice as helpful since b04beaf41d ("intel/vec4: Try both sources as candidates for being immediates"). Haswell and Ivy Bridge had similar results.
