| This JIT buster test checks to see if a JIT doing register allocation |
| on a machine with a callees saves ABI for non-volatile registers can |
| get the exception handling correct. Intel and PowerPC are both such |
| machines. The problem is restoring the correct values of i and j in |
| the catch block. If i and j are never put into registers, then the |
| JIT won't have a problem with correctness because the catch block |
| will load the correct values from memory. If the JIT puts i and j |
| into registers, then restoring their correct values at the catch |
| block gets a little bit tougher. |
