/* On the 88k, parameter registers get stored into the so called "homing" |
area. This *always* happens when you compiled with GCC and use -g. |
Also, (with GCC and -g) the saving of the parameter register values |
always happens right within the function prologue code, so these register |
values can generally be relied upon to be already copied into their |
respective homing slots by the time you will normally try to look at |
them (we hope). |
|
Note that homing area stack slots are always at *positive* offsets from |
the frame pointer. Thus, the homing area stack slots for the parameter |
registers (passed values) for a given function are actually part of the |
frame area of the caller. This is unusual, but it should not present |
any special problems for GDB. |
|
Note also that on the 88k, we are only interested in finding the |
registers that might have been saved in memory. This is a subset of |
the whole set of registers because the standard calling sequence allows |
the called routine to clobber many registers. |
|
We could manage to locate values for all of the so called "preserved" |
registers (some of which may get saved within any particular frame) but |
that would require decoding all of the tdesc information. That would be |
nice information for GDB to have, but it is not strictly manditory if we |
can live without the ability to look at values within (or backup to) |
previous frames. |
