* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)
* Moved some of the CPU cores over to use get_safe_token like other devices. Aaron Giles2009-03-121-8/+8

* New universal dynamic recompiler system. The central module Aaron Giles2008-05-111-0/+418
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.
