-2.2 Keywords
--------------
-
-
- discard Discard fragment.
-
- dst First destination register.
-
- dst0 First destination register.
-
- pc Program counter.
-
- src First source register.
-
- src0 First source register.
-
- src1 Second source register.
-

-
-
-3 Other tokens
-===============
-
-
-3.1 Declaration Semantic
--------------------------
-
-
- Follows Declaration token if Semantic bit is set.
-
- Since its purpose is to link a shader with other stages of the pipeline,
- it is valid to follow only those Declaration tokens that declare a register
- either in INPUT or OUTPUT file.
-
- SemanticName field contains the semantic name of the register being declared.
- There is no default value.
-
- SemanticIndex is an optional subscript that can be used to distinguish
- different register declarations with the same semantic name. The default value
- is 0.
-
- The meanings of the individual semantic names are explained in the following
- sections.
-
-
-3.1.1 FACE
-
- Valid only in a fragment shader INPUT declaration.
-
- FACE.x is negative when the primitive is back facing. FACE.x is positive
- when the primitive is front facing.
