unified memory or instruction memory, under the control of the

single DMAP register.
|

one of the segments. */

set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.

d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,

Clean up the D10V port so that GDB and the target program no

claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the

Clean up the D10V port so that GDB and the target program no
longer disagree on how big pointers are.
* findvar.c (value_from_register): Remove special case code for D10V.
* printcmd.c (print_frame_args): Same.
* valops.c (value_at, value_fetch_lazy): Same.
* values.c (unpack_long): Same.
* gdbarch.sh: Changes to effect the following:
* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,
gdbarch_d10v_daddr_p_ftype, gdbarch_d10v_daddr_p,
set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
gdbarch_d10v_convert_daddr_to_raw_ftype,
gdbarch_d10v_convert_daddr_to_raw,
set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
gdbarch_d10v_convert_iaddr_to_raw_ftype,
gdbarch_d10v_convert_iaddr_to_raw,
set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.

/* The following code implements access to, and display of, the D10V's

|
instruction trace buffer. The buffer consists of 64K or more

|
|
|
4-byte words of data, of which each words includes an 8-bit count,
|
|
|
|
an 8-bit segment number, and a 16-bit instruction address.
|
|
|
|
|
|
|
|
In theory, the trace buffer is continuously capturing instruction
|
|
|
|
data that the CPU presents on its "debug bus", but in practice, the
|
|
|
|
ROMified GDB stub only enables tracing when it continues or steps
|
|
|
|
the program, and stops tracing when the program stops; so it
|
|
|
|
actually works for GDB to read the buffer counter out of memory and
|
|
|
|
then read each trace word. The counter records where the tracing
|
|
|
|
stops, but there is no record of where it started, so we remember
|
|
|
|
the PC when we resumed and then search backwards in the trace
|
|
|
|
buffer for a word that includes that address. This is not perfect,
|
|
|
|
because you will miss trace data if the resumption PC is the target
|
|
|
|
of a branch. (The value of the buffer counter is semi-random, any
|
|
|
|
trace data from a previous program stop is gone.) */

Clean up the D10V port so that GDB and the target program no
longer disagree on how big pointers are.
* findvar.c (value_from_register): Remove special case code for D10V.
* printcmd.c (print_frame_args): Same.
* valops.c (value_at, value_fetch_lazy): Same.
* values.c (unpack_long): Same.
* gdbarch.sh: Changes to effect the following:
* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,
gdbarch_d10v_daddr_p_ftype, gdbarch_d10v_daddr_p,
set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
gdbarch_d10v_convert_daddr_to_raw_ftype,
gdbarch_d10v_convert_daddr_to_raw,
set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
gdbarch_d10v_convert_iaddr_to_raw_ftype,
gdbarch_d10v_convert_iaddr_to_raw,
set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.
