35630a672a - rename Info.plist to Info.plist.in so that I can make the configure script
substitute the correct version number

249131fbed I added a support function to osdep.
The function gets the real time in useconds and puts it in
a Bit64u.  This function is defined when:
BX_HAVE_REALTIME_USEC is 1.

Right now, BX_HAVE_REALTIME_USEC is defined to be BX_HAVE_GETTIMEOFDAY
and bx_get_realtime64_usec is defined in terms of gettimeofday().

However, it could be defined in terms of any other method of obtaining
the current time accurate to the usecond.  That is why I moved the
function to osdep and added the new define.

27e5bd1bd6 - check in minor change in CreateFile() which fixes cdrom access in win2k.
Suggested by Gino Chen Hsiang-Jan in bug [ #470701 ] Win32 CD-ROM
  Need help testing on other windows versions.

30de048055 Enhanced my previous updates, by making sure that both operands
to byte operations in asm() statements use either a byte-accessible
  register (eax,ebx,ecx,edx) or a memory operand with "q" and "mq"
  constraints.
2002-09-23 00:40:58 +00:00
Kevin Lawton
9100d1ab1e Changed "r" constraints to "q", so gcc will emit a byte addressable
register for the x86 asm() tricks.

41929b75bd Moved the "i = &iStorage" line inside the #ifdef bracketing
for iCache support.  It wouldn't hurt anything, but it
  makes the compiler complain of longjmp/fork issues.

e4b5e64048 - modify the RPM build script so that it can build RPMs without root
access.  Now it builds everything within a subdirectory called _rpm_top.
  Some more testing needed in different environments, but it seems to work.

6e7a2e91f2 Added more x86 specific asm() code to directly handle eflags return
values for some common instructions (like test/and/cmp).  Only
  compiles in on x86 of course.
2002-09-22 22:22:16 +00:00
Kevin Lawton
4150ae197e Hopefully this fixes "Bugs item #612880", which was due to
the icache pageStamp check too early, before it was known
  that the TLB entry would produce a physical address in
  range of the normal part of physical memory.  PCI accesses
  were causing seg faults because of this.  I haven't tested
  this for PCI.

a785453194 - fixed another case of get_##flag##(void) 2002-09-22 19:06:46 +00:00
Bryce Denney
fda29cd55b - in definition of ArithmeticalFlag, we had "getB_##flag##(void)",
which says to paste getB_ with flag and then paste with (.  It should
  be "getB_##flag(void)".  Some preprocessors are complaining about pasting
  the symbol with the paren.

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.

ac4e5bb6cf - add sanity checks
- don't allow MMX on cpu level < 5.
  - require FPU support on cpu level >= 55
  - don't allow MMX support without FPU support (moved this check from
    cpu/i387.h to config.h)

Bryce Denney
17f873abc3 - these fixes are from Psyon
- PacketSetReadTimeout: instead of calling with a very short timeout,
  now we call it with -1 which means no timeout.
- Psyon found that Peter Tattam's changes, while necessary for win95, broke
  WinNT/2000.  So now on Windows NT/2000, we still call
  WaitForSingleObject(lpAdapter->ReadEvent,0) but we ignore the return value.

c382348cbf - add CopyParamToGui() to DebugLogDialog, which is empty for now. 2002-09-22 04:52:55 +00:00
Bryce Denney
adeb5331f6 - I used to have a method called ParamDialog::Refresh() that reread all the
parameter values associated with the dialog and updated the wxWindows
  controls.  At the time I didn't realize that I was overriding
  wxWindow::Refresh() which repaints the window.  Later, I renamed the method
  to CopyParamToGui() to make it more clear, but many of the callers in
  wxmain.cc continued to call Refresh(), which now reverted to the parent class
  wxWindow::Refresh().  Since there was no compile error I didn't notice for a
  while, but it caused the ParamDialogs to repaint themselves constantly but
  never actually change their values.  This is now fixed by changing those
  method calls to CopyParamToGui().

Bryce Denney
85a7d1dad8 - on win32, the wxWindows interface was never redrawing the screen since I
started using a wxTimer to trigger the redraws.  Now instead of calling
  MyPanel::OnPaint directly, I call Refresh() instead.  This makes the Windows
  display work correctly.

5933d94c91 - add typecast to Bit32u to avoid lots of useless -Wall warnings. The constant
expression on the right side of the comparison was turning out signed, while
  the expression on the left was unsigned.

de67199921 - call SetFocus() on the panel so that it is certain to get key events.
I'm not sure why this wasn't needed before, but after switching to
  wxWindows 2.3.3 it seems to be important.
- in a wxLogDebug() call I was trying to pass a struct instead of a string.
  Fixed that.

3bfeab23c9 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.

bed405dad0 - revert 1.30. The change I made caused VPATH builds to fail, like when
you run configure from another directory.  We'll have to try some other
  way to make nmake happy.

4c4294cc6f - new variable 'charmap_updated', 'charmap_changed' array renamed to
'char_changed'. These variables are currently only used by the win32 gui for
  the update of the font bitmaps. SDL and wxWindows do not use the variables
  since they are using the charmap data directly
- free text snapshot memory when the user has cancelled the dialog
- write text snapshot file in binary mode (disables the LF -> CRLF conversion
  in cygwin)

e668567e85 Made BX_USE_REALTIME_PIT checked at runtime. This is
a precursor to making it a runtime option.  I'm not
sure how to do this, but it should be trivial.  All it
would take is adding the option and changing the
macro for BX_USE_REALTIME_PIT to point to that option.

44c5829ea5 Realtime PIT with gettimeofday is working beautifully.
It's MUCH smoother than with the time(NULL) version.

We need to work on setting up the config parameters some more.

e2e219eda0 Modified the way that the register field (low 3 bits of a few opcodes
also extended by the REX.B field on Hammer) is passed to instructions.
I rearranged the bxInstruction_c to free up a field to be used
to pass this info when mod-rm bytes are not used.  This got rid
of the ugly ((i->b1 & 7) + i->rex_b) code.

Probably shaved just a very little run time off Hammer emulation,
and even less on x86-32.  The resultant is a little cleaner anyways.

0d68427d37 - we kept getting /usr/include/math.h in the dependency list for keyboard.cc
and I could never explain it.  The problem was that in keyboard.cc it
  included "math.h" with quotes instead of <math.h> with less than/greater
  than, so gcc -MM didn't realize it was a system header.

375fcf648b - plug up some memory leaks in wxWindows code, with help from Valgrind
- MyPanel::blankCursor
  - MyFrame::panel
  - AdvancedLogOptions::action (2d array of wxChoice *'s)
  - ParamDialog::idHash, ParamDialog::paramHash, and ParamStructs
  - file dialog in BrowseTextCtrl
- fix illegal use of a wxObject.  I had been clearing the ParamStruct
  with memset(), but I forgot that ParamStruct was a subclass of wxObject
  so I was trashing the wxObject fields too!  Instead I created a
  ParamStruct constructor that clears the pointers to NULL.
- comment out debug output from AdvancedLogOptionsDialog::SetAction
- modified files: gui/wx.cc gui/wxdialog.cc gui/wxdialog.h
  gui/wxmain.cc gui/wxmain.h
