From 90da8bf5477cb65b9f2e5148c05ef621a09b704f Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 12 Jul 2016 10:53:11 -0700 Subject: glsl: Generate code for constant ir_binop_ldexp expressions ldexp is weird because its two operands have different types. Add support for directly specifying the exact signatures of all the possible variations of an operation. v2: Use tuple() instead of () for clarity. Suggested by Dylan.
