822 ABI suitable for the implementation of a robust extract

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

1405 GDB targets (*-tdep.c) can register an interest in a specific
1406 architecture. Other GDB components can register a need to maintain
1407 per-architecture data.
1408
1409 The mechanisms below ensures that there is only a loose connection
1410 between the set-architecture command and the various GDB

1413
1414 Pragmatics:
1415
1416 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1417 didn't scale.
1418
1419 The more traditional mega-struct containing architecture specific
1420 data for all the various GDB components was also considered. Since
99e7bb18 1421 GDB is built from a variable number of (fairly independent)
