JM		 34 to this file, modifying gdbarch.sh and using its output may prove

825 ABI suitable for the implementation of a robust extract
826 struct-convention return-value address method (the sparc saves the
827 address in the callers frame). All the other cases so far examined,
828 the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
829 erreneous - the code was incorrectly assuming that the return-value
830 address, stored in a register, was preserved across the entire
831 function call.
832 For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
833 the ABIs that are still to be analyzed - perhaps this should simply
834 be deleted. The commented out extract_returned_value_address method
835 is provided as a starting point for the 32-bit SPARC. It, or
836 something like it, along with changes to both infcmd.c and stack.c
837 will be needed for that case to work. NB: It is passed the callers
838 frame since it is only after the callee has returned that this

1387
1388 GDB targets (*-tdep.c) can register an interest in a specific
1389 architecture. Other GDB components can register a need to maintain
1390 per-architecture data.
1391
1392 The mechanisms below ensures that there is only a loose connection
1393 between the set-architecture command and the various GDB
99e7bb18 1394 components. Each component can independently register their need

1396
1397 Pragmatics:
1398
1399 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1400 didn't scale.
1401
1402 The more traditional mega-struct containing architecture specific
1403 data for all the various GDB components was also considered. Since
99e7bb18 1404 GDB is built from a variable number of (fairly independent)
