Description
EInvalidOp is the exception class for undefined or invalid CPU instructions.
EInvalidOp is raised when the CPU encounters an undefined instruction (see the UD2 instruction), invalid operation, or floating-point stack overflow.
Run-time exception information is saved in fields provided by System.SysUtils.EExternal.
Note: Do not confuse EInvalidOp with System.Classes.EInvalidOperation, the exception class for invalid component operations.
