|

819 |
|
|
GDB targets (*-tdep.c) can register an interest in a specific
|
820 |
|
|
architecture. Other GDB components can register a need to maintain
|
821 |
|
|
per-architecture data.
|
822 |
|
|
|
823 |
|
|
The mechanisms below ensures that there is only a loose connection
|
824 |
|
|
between the set-architecture command and the various GDB
|
825 |
|
|
components. Each component can independently register their need
|
826 |
|
|
to maintain architecture specific data with gdbarch.
|
827 |
|
|
|
828 |
|
|
Pragmatics:
|
829 |
|
|
|
830 |
|
|
Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
|
831 |
|
|
didn't scale.
|
832 |
|
|
|
833 |
|
|
The more traditional mega-struct containing architecture specific
|
834 |
|
|
data for all the various GDB components was also considered. Since
|

Register support for the specified ARCHITECTURE with GDB. When

849 |

information available to gdbarch about the (possibly new)

850 |
|

architecture; ARCHES which is a list of the previously created

\`\`struct gdbarch'' for this architecture.

|
854 |
|
|
pre-initialized with information obtained from INFO.ABFD or
|
855 |
|
|
previously selected architecture (if similar). INIT shall ensure

856 |
|
|
that the INFO.BYTE_ORDER is non-zero.
|
857 |

|
|
858 |
|

The INIT function shall return any of: NULL - indicating that it

859 |
|
|
doesn't recognize the selected architecture; an existing \`\`struct
|
860 |
|
|
gdbarch'' from the ARCHES list - indicating that the new
|
861 |
|
|
architecture is just a synonym for an earlier architecture (see
|
862 |
|

gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''

- that describes the selected architecture (see gdbarch_alloc()).

865 |

The DUMP_TDEP function shall print out all target specific values.
