/* There is a LOC_ARG/LOC_REGISTER pair. This means that
it was passed on the stack and loaded into a register,
or passed in a register and stored in a stack slot.
GDB 3.x used the LOC_ARG; GDB 4.0-4.11 used the LOC_REGISTER.
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.

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. */
