6b184eb3b5 - better error handling in function load_ROM():
* cause a BX_PANIC if the path of the system BIOS or VGA BIOS is empty
  * open() and fstat() now cause a BX_ERROR if the rom image is optional

87f1f3a2e0 Apply patch.safe-fullscreen. Comments from the patch follow:
This fixes bug #614724: SDL can get stuck in full-screen mode, and provides
a framework for fixing the problem on other full-screen display libraries
such as term, svga, etc.

- add virtual method bx_gui::set_display_mode(mode) which can be overridden
  by each display library class, if appropriate.  This method is primarily
  used when you run Bochs full screen, to tell the gui to switch from full
  screen back to a mode where you can use the text console.
- There are two display modes: config and simulation.  The mode is changed to
  config mode during logfunctions::ask, during the runtime configuration menu,
  and before displaying a debugger prompt.  It is changed back to simulation
  mode whenever instructions are running.
- Instead of being called directly through the global bx_gui pointer, the
  bx_gui_c::set_display_mode() method is almost always accessed through
  siminterface, like this:
    SIM->set_display_mode (DISP_MODE_CONFIG);
    SIM->set_display_mode (DISP_MODE_SIM);
  Of course siminterface just passes the call on to bx_gui::set_display_mode().
  I added it to siminterface so that the config interfaces could call it.
  (They don't #include bochs.h so they can't access bx_gui.)

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().

c62dda51d3 Bug #640549: dbg fails if wx configured but not on.
- My previous rev to dbg_main.cc caused the debugger to fail when readline
  was disabled.  With these changes I have tested more thoroughly and it works
  with readline enabled or disabled, and with wxWindows enabled and disabled.

eff7720ae7 This fixes bug #640549: dbg fails if wx configured but not on.
- The Bochs debugger uses BX_WITH_WX to decide to change to wxWindows debugger
  behavior: sending a synchronous message to the config interface to get a new
  command, sending all dbg_printf output to the config interface, deciding
  whether to trap control-C, etc.  But now that it's possible to compile with
  BX_WITH_WX and BX_WITH_other_things, this isn't quite right anymore.  With
  this change, we now use calls to a new method SIM->is_wx_selected() to decide
  which behavior to use.  This method is equivalent to checking if the display
  library variable is set to "wx", but it's implemented in such a way that it
  only has to check a boolean for each call to SIM->is_wx_selected().
- in siminterface.cc, init some local variables to 0 to avoid compile
  warnings.

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/*)

1893bf78e1 Disassembly now picks up the current 16/32 bit mode from CS register
by default.

Rearranged the output to make the output instructions always appear in
the same column, which makes them considerably easier to read.

I have *not* done the physical address display changes -- plan to do
that separately.

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.

4c9776fb96 - add -lwinmm to the link lines anytime you use --enable-sb16=win. Now
instead of winmm being a part of GUI_LINK_OPTS_WIN32 only, it is
  placed in @DEVICE_LINE_OPTS@ so that it will be used for sdl, rfb, wx,
  etc.
- solve compile problems when building bximage, niclist, and any other
  console based program.  The compile flags returned by wx-config and
  sdl-config did strange things to these console programs, for example
  redefining main to SDL_main.  Because I wanted to use the
  configure-generated CFLAGS to compile the programs, but I wanted to
  avoid including GUI specific compile options, I split up the configure's
  @CFLAGS@ variable into @CFLAGS@ and @GUI_CFLAGS@, and split
  @CXXFLAGS@ into @CXXFLAGS@ and @GUI_CXXFLAGS@.  All programs in the
  Bochs binary will use both, but the console programs will just use
  @CFLAGS@ or @CXXFLAGS@.
- gui/Makefile.in, I no longer use the gui specific CFLAGS variables,
  SDL_CFLAGS and WX_CXXFLAGS.  These values are included in CFLAGS and
  CXXFLAGS now.
- modified: configure.in, configure, all Makefile.in's

d21ffad632 - fix call to accessor getB_VM() 2002-09-24 20:41:22 +00:00
Kevin Lawton
3c09fdb363 I updated code that was using !!get_CF() (or other arithmetic flag) to
use getB_CF() etc.  getB_CF() and friends are only for a relatively
  small number of cases where a true boolean/binary number (0 or 1) is required
  rather than 0 or non-0 as is returned by get_CF().

140abecb87 - the valid arg of dbg_xlate_linear2phy is declared as Boolean but we were
giving it Bit32u pointers.  On MacOSX for some reason Boolean is set to
  unsigned char instead of unsigned int, so it actually cares that we get the
  type right.

b742ccec7e Changed eflags accessors for get_?F() to use (val32 & (1<<N)) instead
of (1 & (val32>>N)), and added a getB_?F() accessor for special
  cases which need a strict binary value (exactly 0 or 1).  Most
  code only needed a value for logical comparison.  I modified the
  special cases which do need a binary number for shifting and
  comparison between flags, to use the special getB_?F() accessor.

Cleaned up memory.cc functions a little, now that all accesses
  are within a single page.

Fixed a (not very likely encountered) bug in fetchdecode.cc (and
  fetchdecode64.cc) where a 2-byte opcode starting with a prefix
  starts at the last offset on a page.  There were no checks
  on the segment overrides for a boundary condition.  I added them.

The eflags enhancements added just a tiny bit of performance.
