588 | called directly by GDB. | |
589 | ||
590 | In a nutshell, it's not possible for GDB to determine when the address | |

592 | be passed. | |
593 | ||
594 | So, to avoid GDB lossage in the common case, we perform calls through the | |
595 | various function pointers and compare the return values. For the HPPA | |
596 | at least, this allows the common case to work. | |
597 | ||
598 | If one wants to try something more complicated, pass the address of | |
599 | a function accepting a "double" as one of its first 4 arguments. Call | |
600 | that function indirectly through the function pointer. This would fail | |
