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

873 address in the callers frame). All the other cases so far examined,
874 the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
875 erreneous - the code was incorrectly assuming that the return-value
876 address, stored in a register, was preserved across the entire

878 For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
879 the ABIs that are still to be analyzed - perhaps this should simply
880 be deleted. The commented out extract_returned_value_address method
881 is provided as a starting point for the 32-bit SPARC. It, or
882 something like it, along with changes to both infcmd.c and stack.c
883 will be needed for that case to work. NB: It is passed the callers
884 frame since it is only after the callee has returned that this

1430 architecture.
1431
1432 GDB targets (*-tdep.c) can register an interest in a specific
1433 architecture. Other GDB components can register a need to maintain
1434 per-architecture data.
1435
1436 The mechanisms below ensures that there is only a loose connection
1437 between the set-architecture command and the various GDB
99e7bb18 1438 components. Each component can independently register their need
0f71a2f6
JM		 1439 to maintain architecture specific data with gdbarch.
1440
1441 Pragmatics:
1442
1443 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1444 didn't scale.
1445
1446 The more traditional mega-struct containing architecture specific
1447 data for all the various GDB components was also considered. Since
99e7bb18 1448 GDB is built from a variable number of (fairly independent)
0f71a2f6
