-
- Reasons for using the LOC_ARG:
- (1) because find_saved_registers may be slow for remote
- debugging,
- (2) because registers are often re-used and stack slots
- rarely (never?) are. Therefore using the stack slot is
- much less likely to print garbage.
-
- Reasons why we might want to use the LOC_REGISTER:
- (1) So that the backtrace prints the same value as
- "print foo". I see no compelling reason why this needs
- to be the case; having the backtrace print the value which
- was passed in, and "print foo" print the value as modified
- within the called function, makes perfect sense to me.
-
- Additional note: It might be nice if "info args" displayed
- both values.
- One more note: There is a case with sparc structure passing
- where we need to use the LOC_REGISTER, but this is dealt with
- by creating a single LOC_REGPARM in symbol reading. */
