2643 * Set up a sequence of staggered jumps, forwards and backwards with
2644 * increasing offset. This tests the conversion of relative jumps to
2645 * JITed native jumps. On some architectures, for example MIPS, a large
2646 * PC-relative jump offset may overflow the immediate field of the native
2647 * conditional branch instruction, triggering a conversion to use an
2648 * absolute jump instead. Since this changes the jump offsets, another
2649 * offset computation pass is necessary, and that may in turn trigger
2650 * another branch conversion. This jump sequence is particularly nasty
2651 * in that regard.
2652 *
2653 * The sequence generation is parameterized by size and jump type.
2654 * The size must be even, and the expected result is always size + 1.
