[Mesa-dev] [PATCH v2 01/14] glsl: Add new atomic_uint built-in GLSL type.
Francisco Jerez

Tue Oct 1 19:15:31 PDT 2013
v2: Fix GLSL version in which the type became available. Add
contains_atomic() convenience method. Split off atomic counter
comparison error checking to a separate patch that will handle all
opaque types. Include new ir_variable fields for atomic types.
