[Mesa-dev] [PATCH 09/21] glsl: Set ir_instruction::ir_type in the base class constructor
Ian Romanick
idr at freedesktop.org
Tue May 27 19:49:04 PDT 2014
From: Ian Romanick <ian.d.romanick at intel.com>
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.
