The code resides in the gdb
sub-directory. The
main architectural specification is in
or1k-tdep.c
, with and OpenRISC 1000 wide header
in or1k-tdep.h
. Support for the OpenRISC 1000
Remote JTAG interface is in remote-or1k.c
with
the detailed protocol in or1k-jtag.c
and a
protocol header in or1k-jtag.h
.
There are several targets which can use the OpenRISC 1000
architecture. These all begin or16
,
or32
or or32
. The
configure.tgt
is edited to add patterns for these
that will pick up the binaries generated from these source files.

The architecture definition is created from the
_initialize_or1k_tdep
by a call to
gdbarch_register
. That function also initializes
the disassembler (build_automata
) and adds two
new commands: a sub-command to the info command to
read SPRs and a new top level support command,
spr to set the value of SPRs.
