52204a0b 27 The Bourne shell script ``gdbarch.sh'' creates the files

52204a0b 33 changes into that script. Conversely, when making sweeping changes
104c1213
JM		 34 to this file, modifying gdbarch.sh and using its output may prove
35 easier. */

880 address in the callers frame). All the other cases so far examined,
881 the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
882 erreneous - the code was incorrectly assuming that the return-value
883 address, stored in a register, was preserved across the entire
884 function call.
885 For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
886 the ABIs that are still to be analyzed - perhaps this should simply
887 be deleted. The commented out extract_returned_value_address method
888 is provided as a starting point for the 32-bit SPARC. It, or
889 something like it, along with changes to both infcmd.c and stack.c
890 will be needed for that case to work. NB: It is passed the callers
891 frame since it is only after the callee has returned that this

1442 architecture.
1443
1444 GDB targets (*-tdep.c) can register an interest in a specific
1445 architecture. Other GDB components can register a need to maintain
1446 per-architecture data.
1447
1448 The mechanisms below ensures that there is only a loose connection
1449 between the set-architecture command and the various GDB
99e7bb18 1450 components. Each component can independently register their need
0f71a2f6
JM		 1451 to maintain architecture specific data with gdbarch.
1452
1453 Pragmatics:
1454
1455 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1456 didn't scale.
1457
1458 The more traditional mega-struct containing architecture specific
1459 data for all the various GDB components was also considered. Since
99e7bb18 1460 GDB is built from a variable number of (fairly independent)
0f71a2f6

1483 of all the previously created architures for this architecture
1484 family. The (possibly NULL) ARCHES->gdbarch can used to access
1485 values from the previously selected architecture for this
1486 architecture family. The global ``current_gdbarch'' shall not be
1487 used.
