449 | /* This used to simply compare the function pointer arguments with | |
450 | known values for func_val1 and func_val2. Doing so is valid ANSI | |
451 | code, but on some machines (RS6000, HPPA, others?) it may fail when | |
452 | called directly by GDB. | |
453 | ||
454 | In a nutshell, it's not possible for GDB to determine when the address | |
455 | of a function or the address of the function's stub/trampoline should | |
456 | be passed. | |
457 | ||
458 | So, to avoid GDB lossage in the common case, we perform calls through the | |
459 | various function pointers and compare the return values. For the HPPA | |
460 | at least, this allows the common case to work. | |
461 | ||
462 | If one wants to try something more complicated, pass the address of | |
463 | a function accepting a "double" as one of its first 4 arguments. Call | |
464 | that function indirectly through the function pointer. This would fail | |
465 | on the HPPA. */ | |
