- connected EEPROM (doesn't seem to affect much)
- cleaned up system register access
GTI Club driver:
- altered network IRQ clear to fix several problems
- added Guru readme
- fixed crashes due to missing inputs
- gticlub "works" again
ZR107 driver:
- added Guru readme
- cleaned up system register access
- these games work again with altered network IRQ timing
NWK-TR driver:
- added Guru readme
DRC frontend:
- now passes pointer to previous instruction when describing
PPC frontend:
- attempts to roughly take into account branch and CR logical
folding in timing computations
* changed from tracking "live" registers to tracking "necessary" registers
* genericized register tracking to be more flexible
* added previous instruction pointer to opcode descriptions
PowerPC frontend/DRC:
* cleaned up register tracking implementation
* fixed numerous errors and shortcomings in the tracking
* added support for removing unnecessary XER CA and CR0 computations
* updated UML logging to output new frontend statistics
MIPS3 frontend/DRC:
* tweaked register tracking to match new DRC frontend system
* updated UML logging to output new frontend statistics
is drcuml.c, which defines a universal machine language
syntax that can be generated by a frontend recompiler and
then retargeted via a generic backend interface to any of
a number of different architectures. A disassembler for the
UML is also included to allow examination of the generated
UML code.
Currently supported backend architectures include 32-bit x86,
64-bit x86, and a platform-neutral interpreted C backend that
can be used as a fallback for platforms without native
support. The C backend also performs additional validation
to ensure assumptions are met.
Along with the new architecture is a new MIPS III/IV
recompiler frontend. This frontend has been rewritten from
the old x64-specific recompiler to generate UML opcodes
instead. This means that the single recompiler can be used
to target multiple backend architectures and should in
theory produce identical results across all of them.
The old 32-bit and 64-bit MIPS recompilers are now officially
retired. The new system provides similar performance (within
5% generally) to the old system and has similar compatibility.
The only currently known issues are some problems with the
two Gauntlet 3D games.
- removed years from copyright notices
