/* OpCode prediction macros
Some opcodes tend to come in pairs thus making it possible to
predict the second code when the first is run. For example,
- COMPARE_OP is often followed by JUMP_IF_FALSE or JUMP_IF_TRUE. And,
- those opcodes are often followed by a POP_TOP.
+ COMPARE_OP is often followed by POP_JUMP_IF_FALSE or POP_JUMP_IF_TRUE.
Verifying the prediction costs a single high-speed test of a register
variable against a constant. If the pairing was good, then the
