From 0bb3d4ba54f98f4d45abe598dabc905f08055cd5 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sun, 8 Jul 2012 22:27:25 -0700 Subject: [PATCH] glsl/ir_builder: Add a generic constructor for unary expressions. I needed to compute logs and square roots in a patch I was working on, and wanted to use the convenient interface. We already have a similar constructor for binops; adding one for unops seems reasonable.
