### Description of operands
- `rDest`: Represents a destination operand (register).
- `rSrc1`: Represents a so-called SRC1 source operand (register), which allows accessing floating-point vector uniforms and relative addressing.
- `rSrc2`, `rSrc3` and `rSrcF`: They represent other source operands (registers), which are limited to input and scratch registers.
- `rSrc2`: Represents a so-called SRC2 source operand (register), which is limited to input and scratch registers.
- `iReg`: Represents an integer vector uniform source operand.
- `bReg`: Represents a boolean uniform source operand.
- `procName`: Represents the name of a procedure.
