* Fixed failing to call the debugger instruction hook for the first
instruction following an interrupt, exception or trap.
* Use UML branches to emulate non-delayed intra-block branches, avoiding
the expensive "hash jump".
* Re-worked the instruction description code:
- Calculate static branch targets for more instructions.
- Flag instructions that may cause mode changes.
- Don't be so eager to end an instruction sequence.
- Removed the local register input/output flags - FP may no be the
same when executing the code as when describing instructions.
* Fixed interpreter incorrectly setting ILC when an interrupt
immediately follows a RET instruction.
* Fixed recompiler flag calculation regressions, and optimised a little.
* Fixes interrupts not being serviced while tracing.
* Further improves recompiler performance.
* Fixes recompiler interrupt check function calling itself recursively.
* Also added debugger exception hook calls to interpreter and recompiler.
* Fixed XM (index move) instructions failing to update the destination
register on range error for interpreter and recompiler.
* Fixed double-word stores when the source indicates SR (both stored
words are zero) for interpreter and recompiler.
* Fixed recompiler failing to set ILC and P on range error and frame
error exceptions.
* Optimised recompiled code for word size shifts.
* Pushed more recompiler logic from run-time to code generation time and
simplified delay slot PC check and trace check logic.
* Use MOV rather than LOAD where possible in recompiler to improve code
generation performance and symbolic memory locatin names in
disassembled UML.
* Updated TODO list in header comment, reduced copy/paste some more.

New clones marked not working
-----------------------------
Chao Ji Da Heng 2 (V311CN, alternate GFX ROMs) [little0]
- Added support for dynamic size chars lines.
That fixes the paytable shown in different games
such as dphl, dphljp, dphlunkb, sureshoto, smshilo,
etc, allowing to remove the imperfect graphics flags.
- norautua: fixed the overflow when drawing cards
in the possible straight case.
- Rewrote the screen update to save a big number of lines.
- Removed the driver init for ssjkrpkr.
- Added Inputs & DIP switches for gtipoker.
- Change gtipoker game description to: Aces or Better Draw Poker.
- Rearrange the gtipoker graphics ROM.
- Promoted gtipoker set to working.
- Added technical notes.
Systems promoted to working
---------------------------
Aces or Better Draw Poker (GTI) [Roberto Fresca, Grull Osgo]
cpu/e132xs: Implemented supervisor and trace modes as recompiler modes.
This eliminates or simplifies a lot of run-time checks. In particular,
the trace checks on every instruction are not generated when not
tracing, and simplified to just checking the P bit when tracing.
cpu/e132xs: Optimised code generation for RET, avoid a redundant load
when checking for an overflow trap, use the exception parameter for
exception codes rather than generating one function for each possible
code. Also simplified interpreter code for RET.
cpu/e132xs: Implemented SUMS for the recompiler.
cpu/e132xs: Implemented privilege check for setting L (interrupt
lockout) for recompiler. Not implemented for interpreter.
cpu/e132xs: Partially fixed tracing. P flag should be set by all
instructions except RET. Trace exceptions are not triggered for
branches when using the recompiler.
cpu/e132xs: Fixed ILC being set incorrectly for RET.
cpu/drcbex64.cpp: Avoid unnecessary expensive operations when a shift
operation request the zero and/or sign flags but not the carry flag.
* Also avoid an redundant load when checking if trace is active.
* Reduces generated native instruction count by about 24% on x86-64 and
gives an overall performance improvement of about 3.5% in -bench
scores.
- Simplified ROM/RAM banking.
- Added Alpha and Numerical keyboards for POS variants.
- Applied software list filters.
- Added topslot for Organiser II variants.
- Removed fake LZ64S model, ROMs moved to LZ64.
psion/psion_pack.cpp: Allow setting image_interface.
New working clones
------------------
Organiser II Alpha POS 200 [Nigel Barnes, Jaap Scherphuis]
Organiser II P 250 [Nigel Barnes, Jaap Scherphuis]
Organiser II P 432 [Nigel Barnes, Jaap Scherphuis]
* Made interrupt check function generate far more compact code (about
85% reduction in number of native instructions on x86-64).
* Optimised out-of-cycles check.
* Applied prior optimisation for trap/interrupt checks to static
exception checks as well (code is still copy/pasted).
* Hi-hat decay knob is now working.
* Open and closed hats have different decays.
* Better default tuning for the snare.
* Removed `strobe_` prefix from functions where it was redundant. Made it an argument in a function where it matters.
New systems marked not working

MICE-IIIS 68000 [ArcadeHacker]
Also renamed "Microtek International" to just "Microtek" as manufacturer name on the driver for older MICE models (the commercial brand was "Microtek", without any suffix).

Turnier Dart [Victor Fernandez (City Game)]
New clones marked not working
------------------------------
Turnier Dart (HB8-97) [Victor Fernandez (City Game)]
- igs/spoker.cpp: dumped missing GFX ROM for jinhulu2101is and cjdh6. Renamed cjdh6 to huahuas2a as it was misnamed [little0]
- igs/spoker.cpp: implemented more tile banking bits following Haze's IGS033 implementation, gives correct GFX for the sets which use that chip without breaking the ones using the IGS001 / IGS002 combo
