Author: Ilia Mirkin <[email protected]> Date: Sat May 3 00:26:14 2014 -0400 nv50/ir: allow load propagation when flags are defined The old condition disallowed load propagation any time flags were defined, even with e.g. set and a constbuf reference. The new condition disallows it only with immediate propagation. (There are no opcodes that set the condition flag and have an immediate argument.)
