disableCounting

public static void disableCounting()

Disable opcodes counting. It is useful for tests.

To do:

#65:30min Remove public static method 'disableCounting()' from Opcode. Currently it is used in tests. We should find another way to disable opcodes counting in tests. When we find the way to do it, we should remove this method.
