From: Ian Romanick Date: Tue, 11 Dec 2012 20:56:03 +0000 (-0800) Subject: glsl: Replace most default cases in switches on GLSL type X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ecfb404e8d4fcd35524d1c4b3421e24980fe3976;p=mesa.git glsl: Replace most default cases in switches on GLSL type This makes it easier to find switch-statements that need to be updated after a new GLSL_TYPE_* is added because the compiler will generate a warning. Switch-statements that only had a small number of cases (e.g., everything in ir_constant_expression.cpp) were not modified. I may regret that decision when we eventually add support for doubles.
