L1OperandType

enum L1OperandType : Enum<L1OperandType>

An L1 instruction consists of an L1Operation and its operands, each implicitly described by the operation's L1OperandTypes. These operand types say how to interpret some integer that occurs as the encoding of an actual operand of an instruction.

IMMEDIATE

The integer in the nybblecode stream is to be treated as itself, a simple integer.

LITERAL

The integer in the nybblecode stream is to be treated as an index into the current compiled code object's literals. This allows instructions to refer to arbitrary AvailObjects.

LOCAL

The integer in the nybblecode stream is to be treated as an index into the arguments and local variables of the continuation. The arguments come first, numbered from 1, then the local variables.

OUTER

The integer in the nybblecode stream is to be treated as an index into the current function's captured outer variables.
