From: Ian Romanick Date: Wed, 28 May 2014 02:49:04 +0000 (-0700) Subject: glsl: Set ir_instruction::ir_type in the base class constructor X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=963bd99f03781068610a912516377cbfb69ce3c0;p=mesa.git glsl: Set ir_instruction::ir_type in the base class constructor This has the added perk that if you forget to set ir_type in the constructor of a new subclass (or a new constructor of an existing subclass) the compiler will tell you... instead of relying on ir_validate or similar run-time detection.
