 /**
  * \file ir_set_program_inouts.cpp
  *
- * Sets the InputsRead and OutputsWritten of Mesa programs.
- *
- * Additionally, for fragment shaders, sets the InterpQualifier array, and the
- * IsCentroid and IsSample bitfields.
+ * Sets the inputs_read and outputs_written of Mesa programs.
  *
  * Mesa programs (gl_program, not gl_shader_program) have a set of
  * flags indicating which varyings are read and written.  Computing
  * which are actually read from some sort of backend code can be
  * tricky when variable array indexing involved.  So this pass
- * provides support for setting InputsRead and OutputsWritten right
+ * provides support for setting inputs_read and outputs_written right
  * from the GLSL IR.
