From b633ddeb9fd951ddc49e8a3fd25a946e5a16361f Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 14 Jun 2011 13:04:32 -0700 Subject: [PATCH] i965/fs: Implement new ir_unop_u2i and ir_unop_i2u opcodes. No MOV is necessary since signed/unsigned integers share the same bit-representation; it's simply a question of interpretation. In particular, the fs_reg::imm union shouldn't need updating.
