- add RCS Id to header of every file. This makes it easier to know what's going on when someone sends in a modified file.

- parts of the SMP merge apparantly broke the debugger and this revision tries to fix it. The shortcuts to register names such as AX and DL are #defines in cpu/cpu.h, and they are defined in terms of BX_CPU_THIS_PTR. When BX_USE_CPU_SMF=1, this works fine. (This is what bochs used for a long time, and nobody used the SMF=0 mode at all.) To make SMP bochs work, I had to get SMF=0 mode working for the CPU so that there could be an array of cpus. When SMF=0 for the CPU, BX_CPU_THIS_PTR is defined to be "this->" which only works within methods of BX_CPU_C. Code outside of BX_CPU_C must reference BX_CPU(num) instead. - to try to enforce the correct use of AL/AX/DL/etc. shortcuts, they are now only #defined when "NEED_CPU_REG_SHORTCUTS" is #defined. This is only done in the cpu/*.cc code.

merge in BRANCH-io-cleanup. To see the commit logs for this use either cvsweb or cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files. In general this provides a generic interface for logging. logfunctions:: is a class that is inherited by some classes, and also . allocated as a standalone global called 'genlog'. All logging uses . one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this . class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros . respectively. . . An example usage: . BX_INFO(("Hello, World!\n")); iofunctions:: is a class that is allocated once by default, and assigned as the iofunction of each logfunctions instance. It is this class that maintains the file descriptor and other output related code, at this point using vfprintf(). At some future point, someone may choose to write a gui 'console' for bochs to which messages would be redirected simply by assigning a different iofunction class to the various logfunctions objects. More cleanup is coming, but this works for now. If you want to see alot of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1. Comments, bugs, flames, to me: todd@fries.net
