- """Parameters:
-
- - name is the name of the opcode (prepend nir_op_ for the enum name)
- - all types are strings that get nir_type_ prepended to them
- - input_types is a list of types
- - algebraic_properties is a space-seperated string, where nir_op_is_ is
- prepended before each entry
- - const_expr is an expression or series of statements that computes the
- constant value of the opcode given the constant values of its inputs.
-
- Constant expressions are formed from the variables src0, src1, ...,
- src(N-1), where N is the number of arguments. The output of the
- expression should be stored in the dst variable. Per-component input
- and output variables will be scalars and non-per-component input and
- output variables will be a struct with fields named x, y, z, and w
- all of the correct type. Input and output variables can be assumed
- to already be of the correct type and need no conversion. In
- particular, the conversion from the C bool type to/from NIR_TRUE and
- NIR_FALSE happens automatically.
-
- For per-component instructions, the entire expression will be
- executed once for each component. For non-per-component
- instructions, the expression is expected to store the correct values
- in dst.x, dst.y, etc. If "dst" does not exist anywhere in the
- constant expression, an assignment to dst will happen automatically
- and the result will be equivalent to "dst = <expression>" for
- per-component instructions and "dst.x = dst.y = ... = <expression>"
- for non-per-component instructions.
