Field Detail

MAX_INSTRUCTIONS

public static final int MAX_INSTRUCTIONS

Code generation uses no jumps and no switches. Thus, every instruction has at most 4 bytes, and thus, a limit of 16000 instructions seems a save bet for not exceeding Java's 64k limit. (Testing has shown that 30000 would work as well.)

MIN_INSTRUCTIONS

public static final int MIN_INSTRUCTIONS
