| 2642 | * Set up a sequence of staggered jumps, forwards and backwards with |
| 2643 | * increasing offset. This tests the conversion of relative jumps to |
| 2644 | * JITed native jumps. On some architectures, for example MIPS, a large |
| 2645 | * PC-relative jump offset may overflow the immediate field of the native |
| 2646 | * conditional branch instruction, triggering a conversion to use an |
| 2647 | * absolute jump instead. Since this changes the jump offsets, another |
| 2648 | * offset computation pass is necessary, and that may in turn trigger |
| 2649 | * another branch conversion. This jump sequence is particularly nasty |
| 2650 | * in that regard. |
| 2651 | * |
| 2652 | * The sequence generation is parameterized by size and jump type. |
| 2653 | * The size must be even, and the expected result is always size + 1. |
| 2654 | * Below is an example with size=8 and result=9. |
