On the TS2, the first two segments (0x0000 -- 0x3fff, 0x4000 --
0x7fff) always map to the on-chip data RAM, and the fourth always
maps to I/O space. The third (0x8000 - 0xbfff) can be mapped into
unified memory or instruction memory, under the control of the
single DMAP register.
On the TS3, there are four DMAP registers, each of which controls
one of the segments. */

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.) */

Since no registers are convertible now, register generic_register_convertible_not as the gdbarch_register_convertible method instead of d10v_register_convertible.
