* Modified the makefile to support experimental optional C++ Aaron Giles2009-02-281-32/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | compilation: - new option CPP_COMPILE to trigger this (off by default) - split CFLAGS into common, C-only, and C++-only flags - when enabled, CPP_COMPILE causes 'pp' to be appended to the target name NOTE THAT THE SYSTEM CANNOT ACTUALLY BE COMPILED THIS WAY YET. IT IS JUST AN EXPERIMENT. Modified lib.mak to always build zlib/expat as C regardless of CPP_COMPILE. Modified windows.mak to fix warnings with MAXOPT=1, and to leverage the new CFLAGs definitions. Modified vconv.c to do appropriate conversions for new C++ options. Updated sources so that libutil, libocore (Windows), and libosd (Windows) can be cleanly compiled as C or C++. This was mostly adding some casts against void *. Fixed a few more general obvious problems at random locations in the source: - device->class is now device->devclass - TYPES_COMPATIBLE uses typeid() when compiled for C++ - some functions with reserved names ('xor' in particular) were renamed - nested enums and structs were pulled out into separate definitions (under C++ these would need to be scoped to be referenced) - TOKEN_VALUE cannot use .field=x initialization in C++ :(
* Removed DEBUGGER flag from makefile and ENABLE_DEBUGGER Aaron Giles2008-06-261-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macro from the source code. All MAME builds now include the debugger, and it is enabled/disabled exclusively by the runtime command-line/ini settings. This is a minor speed hit for now, but will be further optimized going forward. Changed the 'd' suffix in the makefile to apply to DEBUG builds (versus DEBUGGER builds as it did before). Changed machine->debug_mode to machine->debug_flags. These flags now indicate several things, such as whether debugging is enabled, whether CPU cores should call the debugger on each instruction, and whether there are live watchpoints on each address space. Redesigned a significant portion of debugcpu.c around the concept of maintaining these flags globally and a similar, more complete set of flags internally for each CPU. All previous functionality should work as designed but should be more robust and faster to work with. Added new debugger hooks for starting/stopping CPU execution. This allows the debugger to decide whether or not a given CPU needs to call the debugger on each instruction during the coming timeslice. Added new debugger hook for reporting exceptions. Proper exception breakpoints are not yet implemented. Added new module debugger.c which is where global debugger functions live.
* PowerPC dynamic recompiler: [Aaron Giles] Aaron Giles2008-06-051-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - rewrote PowerPC implementation as a dynamic recompiler on top of the universal recompiler engine - wrote a front-end to analyze PowerPC code paths and register usage - wrote a common shared module with C implementations of tricky CPU behaviors - added separate CPU types for the variants supported, instead of relying on a hidden model enum - rewrote the serial port emulation for the 4xx series to be more accurate and not rely on separate DMA handlers - rewrote the MMU handling to implement a software TLB that faults in pages and handles changed bits appropriately - implemented emulation of the PowerPC 603's software TLB, which allows the model 3 games to run without a hack to disable the MMU Updated the PowerPC disassembler to share constants with the rest of the core, and to more aggressively use simplified mnemonics, especially for branches. [Aaron Giles] Universal recompiler: - fixed frontend to handle opcode widths different from bus width - added several new opcodes: * (D)GETFLGS - copies the UML flags to a destination operand * FDRNDS - rounds a double precision value to single precision - renamed several opcodes: * SETC -> CARRY * XTRACT -> ROLAND * INSERT -> ROLINS - consolidated the following opcodes: * LOAD?U -> LOAD * LOAD?S -> LOADS * STORE? -> STORE * READ?U -> READ * READ?M -> READM * WRITE? -> WRITE * WRITM? -> WRITEM * SEXT? -> SEXT * FTOI?? -> FTOINT * FFRI? -> FFRINT * FFRF? -> FFRFLT - removed some opcodes: * FLAGS - can be done with GETFLGS/LOAD4/ROLINS * ZEXT - can be achieved with AND * READ?S - can be achieved with READ/SEXT - updated C, x86, and x64 back-ends to support these opcode changes - updated disassembler to support these opcode changes MIPS3 dynamic recompiler: - updated to use new/changed opcode forms - changed context switch so that it only swaps a single pointer Konami Hornet changes: [Aaron Giles] - updated to new PowerPC configurations - updated some memory handlers to be native 8-bit handlers - cleaned up JVS implementation to work with new serial code - added fast RAM for the work RAM to give a small speed boost Konami GTI Club changes: [Aaron Giles] - updated to new PowerPC configurations - updated some memory handlers to be native 8-bit handlers Konami Viper/ZR107 changes: [Aaron Giles] - updated to new PowerPC configurations Sega Model 3 changes: [Aaron Giles] - updated to new PowerPC configurations - reimplemented/centralized interrupt handling - these games are broken for the moment Fixed crasher due to some Konami games using 8 layers in the K056832 implementation, even though it was only written for 4. [Aaron Giles] Added fisttp opcode to i386 disassembler. [Aaron Giles]
* New universal dynamic recompiler system. The central module Aaron Giles2008-05-111-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* From: Marc Sandusky Aaron Giles2008-04-021-0/+8
| | | | | | | | | | | | | | | Subject: Minor patch submission - verbose build information for development in IDE I am submitting this minor patch that adds verbose build information to the build output when the "VERBOSE" flag is set to "1", rather than the simple output normally seen, by adding the "-v" flag to the CFLAGS variable. This is most useful for those that like to use an IDE (Eclipse in my case) for source browsing and development. The IDE usually will parse the build information, which is currently not available, to determine include file locations, build definitions, etc. and will use that information to provide more advanced navigation features.
* Followup to r767: Couriersud2008-02-221-0/+14
| | | * submit changes to makefile omitted in r767
* Changed debugger-related code to be based off a new makefile define ↵ Aaron Giles2008-02-021-3/+11
| | | | | | | | | | | | | (DEBUGGER) which sets a new compile-time define (ENABLE_DEBUGGER). This means that MAME_DEBUG no longer means "enable debugger", it simply enables debugging features such as assertions and debug code in drivers. Also removed the various levels of opbase protection in memory.h and always just turned on full bounds checking. Fixed build break due to missing ampoker.lay -> ampoker2.lay renaming.
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
| | | | | | - removed years from copyright notices - removed redundant (c) from copyright notices - updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* (From Oliver Stoneberg) Aaron Giles2008-01-041-1/+0
| | | | | | | | | | | | | | | | | beastrzb097u2red.patch - added GAME_NOT_WORKING flag, so this bogus bug report can be removed (not even worth 1 buck!) 20080104_1.patch - fixes a memory in src/mame/machine/stvcd.c memoryleak0118u1ora.patch - fixes a memory leak, that only happened when no RawInput API was available memory_leak0111u6ora_1.patch - only a partial patch - model3.c still missing
