An indirect jump makes -it easier to make the jump target modification atomic. On some host -architectures (such as x86 or PowerPC), the @code{JUMP} opcode is -directly patched so that the block chaining has no overhead. - BTW I wouldn't avoid the term TCG ops, it's sometimes clearer than operations.
