* cpu/uml.cpp: Fixed some cases where simplifying multiplication
instructons incorrectly changed output flags.
* cpu/drcbex64.cpp: Fixed some cases where a ROLC/RORC with zero shift
count could incorrectly clear the carry flag.
* cpu/drcbex86.cpp: Made 64-bit ROLC/RORC with zero bit count preserve
the carry flag.
* cpu/drcbec.cpp: Fixed FSMOV/FDMOV turning things that look like
signalling NaNs into quiet NaNs on i686.
* cpu/drcbex64.cpp: Greatly reduced copy/paste in the code generation
for multiply instructions.
|
|
|
|
|
|
| |
* Also added a few more simplifications.
* cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Removed more speical cases for
things the simplifier deals with.

* cpu/drcbec.cpp: Don't clear carry flag on a zero-bit rotate through
carry.
* cpu/drcbex86.cpp: Don't clear carry flag on a word-sized zero-bit
rotate through carry (64-bit case is more involved).
* cpu/drcbex64.cpp: Removed code for another special case of ROLAND that
the simplifier deals with.
-konami/ksys573.cpp, bus/pccard/linflash.cpp: Corrected "Gacha Gachamp".

* Actually take a voltage snapshot when R or C change. This was being attempted, but didn't work because set_target_v would exit early if the target V was not changing. Made the snapshoting more explicit.
* Consider the EG done based on elapsed time, instead of proximity to target value. Some low volume DMX sounds were affected by this.

code: (#13491)
* Implement device_palette_interface for color palette functionality.
* Added some missing members to save states, and use fixed-size integer types for members that need to be saved.
* Moved many internal functions into protected: and private: sections.
* Use more appropriate integer types, made many local variables const.

GitHub #13329.
This was "working" on x86-64 due to the backend treating shift/rotate
instructions with zero immediate bit count as a no-op even if the source
and destination registaer aren't the same. Fixing the bug in the
back-end caused it to break the same way on x86-64 as it does on the
other three back-ends that didn't have this bug.

* Fixed many cases that could cause the upper bits of a register not to
cleared following a 32-bit operation.
* Added more simplifications.
* Allow many simplifications when flag updates are requested.
* Fixed various bits of unreachable code.
* cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Removed code for special-casing
some situations the simplifier can now take care of consistently.
-cpu/drcbex64.cpp: Fixed a bug causing some shifts to be treated as a
no-op when the destination and source are not the same.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Added a special case for
comparing something to itself.
-cpu/e132xs: Use the CARRY instruction rather than a right shift to set
up carry in.

* There are no byte enable or write strobe signals for I/O, and there's
only a single operand size, so word addresses make more sense.
* Also changed STBS/STWS to allow any valid signed or unsigned value of
the applicable size. This allows vamphalf attract mode to work as
well as the storage test.
-misc/limenko.cpp: Better input types for spotty.

* Only a single I/O access is generated for an I/O word read/write. The
upper half just disappears if the pins aren't present. This fixes
"phantom" I/O accesses, allowing address maps to be cleaned up a bit.
* Reduced I/O address width for models with 16-bit external bus to match
hardware.
* Made addressing consistent between interpreter and recompiler for I/O
double-word accesses.
* Implemented power down via internal I/O write for E1-X and later
cores (none of the games I tested actually use it).
-misc/pasha2.cpp: Enabled the recompiler for Zooty Drum - it gets just
as far as the interpreter now.

* Got package option (T, N or B suffix) out of device type.
* Enabled 4x PLL clock multiplier for GMS30C2216/GMS30C2232.
* Implemented entering power down mode via MCR for E1 and E1-X cores.
* Marginally better code generation for a few instructions.
* Log available bus/memory configuration options for different cores.
* Added post load handler for E1-XS and E1-XSR cores to install SDRAM
mode/configuration handlers if necessary.
* Improved comment about different Hynix and Hyperstone CPU models.
-cpu/drcbearm64.cpp: Don't update flags that aren't requested in a few
places.

* Assume ROL sets the V and C flags the same way as SHL and MOVI clears
the V flag.
-cpu/drcbex64.cpp: Optimise SUB x,0,y to a NEG instruction (gets down to
one instruction from two or three a lot of the time). This had been a
TODO comment for ages.
-cpu/drcbex86.cpp: Got rid of unnecessary std::function use. This
substantially reduces the code size and reduces allocations during code
generation.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp, cpu/drcbex86.cpp: Got rid of the
intermediate tables in favour of bit switch statements. This improves
startup time, reduces code size, and gives the compiler more
optimisation opportunities.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp, cpu/drcbex86.cpp: Got rid of
asmjit namespace qualifiers left over from when the class declarations
were in headers and hence outside the scope of the using namespace
statements.

* Fixed behaviour of delayed branches, trace exceptions, and saved PC
calculation for error exceptions in delay slots for the interpreter.
All instructions in delay slots, branching instructions that can raise
exceptions and tracing shoud now (mis)behave properly for the
interpreter, including things the manual says you shouldn't do.
* Fixed and optimised flag updates for left shifts for the recompiler.
* Optimised ROL instruction for the recompiler and made flag calculation
equivalent to the interpreter both with and without the "Missioncraft
flags" compile-time option.
* Only block interrupts for one instruction following a delayed branch.
* Optimised the SOFTWARE instruction a little for the recompiler.
* Added more SDRAM configuration logging and cleaned up code a bit.
-cpu/drcbearm64.cpp: Apply the change from 7efe37938f9dd6a366e to OR and
XOR instructions as well, and fix some cases where a 32-bit logical
operation would fail to clear the upper bits of a register.
-cpu/drcbex64.cpp: Avoid more conditional branches on conditional MOV.
