Message

Unknown comparison operator code in CMP_BR instruction

The VM encountered a CMP_BR_* instruction whose first operand byte (the comparison-operator code) does not match any defined value in opcode::cmp_op (EQ, NE, LT_S, LE_S, GT_S, GE_S).

This error should not occur during normal operation. It indicates a bug in the IronPLC compiler or VM, or that the bytecode has been corrupted or hand-modified.

Report this as a bug at https://github.com/ironplc/ironplc/issues with the .iplc file and the source program that produced it.

Think IronPLC is wrong about this?

If you believe this diagnostic is incorrect, open an issue on GitHub with a small sample that demonstrates the problem.
