1615 | Reasons for using the LOC_ARG: | |
1616 | (1) because find_saved_registers may be slow for remote | |

1618 | (2) because registers are often re-used and stack slots | |
1619 | rarely (never?) are. Therefore using the stack slot is | |
1620 | much less likely to print garbage. | |
1621 | ||
1622 | Reasons why we might want to use the LOC_REGISTER: | |
1623 | (1) So that the backtrace prints the same value as | |
1624 | "print foo". I see no compelling reason why this needs | |
1625 | to be the case; having the backtrace print the value which | |
1626 | was passed in, and "print foo" print the value as modified | |
1627 | within the called function, makes perfect sense to me. | |
1628 | ||
1629 | Additional note: It might be nice if "info args" displayed | |
1630 | both values. | |
c0c9b923 | 1631 | One more note: There is a case with sparc structure passing |
314e6bf3 JG |
