MX_TESTFILE environment variable can be used to specify (and preserve) the test list file used by 'mx unittest'.
This is useful when wanting to run the command under gdb.

| 24 !! Prototype: int SafeFetch32 (int * adr, int ErrValue) | |
| 25 !! The "ld" at Fetch32 is potentially faulting instruction. | |
| 26 !! If the instruction traps the trap handler will arrange | |
| 27 !! for control to resume at Fetch32Resume. | |
| 28 !! By convention with the trap handler we ensure there is a non-CTI | |
| 29 !! instruction in the trap shadow. | |
| 30 !! | |
| 31 !! The reader might be tempted to move this service to .il. | |
| 32 !! Don't. Sun's CC back-end reads and optimize code emitted | |
| 33 !! by the .il "call", in some cases optimizing the code, completely eliding it, | |
| 34 !! or by moving the code from the "call site". | |
