- 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.

Now devices could be compiled separatelly from CPU Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

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

Replace BxAnother attribute in fetchdecode by table lookup like it is done in disasm. This is done in preparation to feature huge fetchdecode change - all fethdecode tables will be duplicated and made separatate table for ModC0 and others. So ALL instructions will emjoy SplitMod11b automatically (if they want). After splitting ALL instruction I hope to get 20% speedup at least.

Changes list made after CVS service crash: - Fixed critical bug in CPU code added with one of the prev commits - Disasm support for SSE4 - Rename PNI->SSE3 everywhere in the code - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode - Fixed ENTER and LEAVE instructions in x86-64 mode - Added ability to turn ON instruction trace, only GUI support is missed. Instruction trace could be enabled if Bochs was compiled with disasm - More changes Bit32u -> bx_phy_address - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK - Small code cleanup - Update CHANGES and user docs

Changes list made after CVS service crash: - Fixed critical bug in CPU code added with one of the prev commits - Disasm support for SSE4 - Rename PNI->SSE3 everywhere in the code - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode - Fixed ENTER and LEAVE instructions in x86-64 mode - Added ability to turn ON instruction trace, only GUI support is missed. Instruction trace could be enabled if Bochs was compiled with disasm - More changes Bit32u -> bx_phy_address - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK - Small code cleanup - Update CHANGES and user docs

Merged patch-unallowed-lock-cases patch. According to the Intel manuals: The LOCK prefix can be prepended only to the following instructions and only to those forms of the instructions where the destination operand is a memory operand: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG, CMPXCH8B, DEC, INC, NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG. If the LOCK prefix is used with one of these instructions and the source operand is a memory operand, an undefined opcode exception (#UD) will be generated. An undefined opcode exception will also be generated if the LOCK prefix is used with any instruction not in the above list. Checking of the LOCK prefix done in fetchDecode state and not overloads Bochs's execution.

Split out JZ/JNZ instructions from JCC because they were called so frequently. Coded asm() statements for INC/DEC_ERX() instructions. Cleaned up the iCache a litle including a bug fix. The generation ID was decrementing the whole field including some high meta bits. That could roll over after 1 Billion cycles. I know only decrement if the field is valid, to save the write. I implemented inline functions which can serve the value of the arithmetic flags if they are cached, and redirect to the lazy_flags.cc routines if not. Most of this was just prep work for adding more asm() statements for native eflags processing when on x86.

Committed patches/patch-bochs-instrumentation from Stanislav. Some things changed in the ctrl_xfer*.cc, fetchdecode*.cc, and cpu.cc since the original patches, so I did some patch integration by hand. Check the placement of the macros BX_INSTR_FETCH_DECODE_COMPLETED() and BX_INSTR_OPCODE() in cpu.cc to make sure I go them right. Also, I changed the parameters to BX_INSTR_OPCODE() to update them to the new code. I put some comments before each of these to help determine if the placement is right. These macros are only compiled in if you are gathering instrumentation data from bochs, so they shouldn't effect others.
