d6f85c12f6 NMI support inside the CPU.

6fe8e9260b remove redundant CPU LEVEL checks for x86-64 2003-12-29 21:47:36 +00:00
Kevin Lawton
a17d06abcb Optimized the main cpu loop iCache checks to remove a redundant
check.

Commented out a number of instances of invalidate_prefetch_q(),
for branches which do not change CS since the EIP window mechanism
takes care of validating that EIP lands in the current page or not
in the main cpu loop anyways.

Fixed a couple cases (v8086 mode and real mode) of loading CS where
the EIP page window was not invalidated in segment_ctrl_pro.cc.
That may fix some aliasing problems reported before (OS2).

cdfc3cbce4 instrumentation enchancements:
* renamed CPU_ID to BX_CPU_ID.
  with this new name there is no possibility for name contentions and BX_CPU_ID
  definition could be moved out to NEED_CPU_REG_SHORTCUTS block

* returned back `unsigned BX_CPU::which_cpu(void)` function

* added BX_CPU_ID parameter for
	BX_INSTR_PHY_READ(a20addr, len);
	BX_INSTR_PHY_WRITE(a20addr, len);
    now it will be
	BX_INSTR_PHY_READ(cpu_id, a20addr, len);
	BX_INSTR_PHY_WRITE(cpu_id, a20addr, len);

dcedff8d46 - fix some minor compile bugs that appear when you mix up instrumentation,
debugger, SMP, and x86-64.  A few macros were missing the CPU_ID argument,
  and a few passed nonexistent variables to the instrumentation macros.
- I changed CPU_ID into a plain old macro instead of an inline call to a
  trivial which_cpu() function, and removed which_cpu().

0a7cb3a43c - apply patch.ifdef-disabled-options. Comments from that patch are below:
For a whole lot of configure options, I put #if...#endif around code that
  is specific to the option, even in files which are normally only compiled
  when the option is on.  This allows me to create a MS Visual C++ 6.0
  workspace that supports many of these options.  The workspace will basically
  compile every file all the time, but the code for disabled options will
  be commented out by the #if...#endif.

  This may one day lead to simplification of the Makefiles and configure
  scripts, but for the moment I'm leaving Makefiles and configure scripts
  alone.

  Affected options:
    BX_SUPPORT_APIC (cpu/apic.cc)
    BX_SUPPORT_X86_64 (cpu/*64.cc)
    BX_DEBUGGER (debug/*)
    BX_DISASM (disasm/*)
    BX_WITH_nameofgui (gui/*)
    BX_SUPPORT_CDROM (iodev/cdrom.cc)
    BX_NE2K_SUPPORT (iodev/eth*.cc, iodev/ne2k.cc)

cec9135e9f - Apply patch.replace-Boolean rev 1.3. Every "Boolean" is now changed to a
"bx_bool" which is always defined as Bit32u on all platforms.  In Carbon
  specific code, Boolean is still used because the Carbon header files
  define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
  The bug was that some code in Bochs depends on Boolean to be a
  32 bit value.  (This should be fixed, but I don't know all the places
  where it needs to be fixed yet.)  Because Carbon defined Boolean as
  an unsigned char, Bochs just followed along and used the unsigned char
  definition to avoid compile problems.  This exposed the dependency
  on 32 bit Boolean on MacOS X only and led to major simulation problems,
  that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
  our own type.  I chose bx_bool for several reasons.
  1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
     platforms, which makes it much less likely to have more platform-specific
     simulation differences in the future.  (I spent hours on a borrowed
     MacOSX machine chasing bug 618388 before discovering that different sized
     Booleans were the problem, and I don't want to repeat that.)
  2. We still have at least one dependency on 32 bit Booleans which must be
     fixed some time, but I don't want to risk introducing new bugs into the
     simulation just before the 2.0 release.
