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.
- 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
- put off some log related features until later
- advanced log options and debug log are done, so I removed them from the list
- added some wxWindows coding hints I found on usenet
interface) by using get/set_default_log_action. This has very minimal effect
on the behavior of the text config interface.
- modified: main.cc gui/control.cc
time, so I've tried to improve it. Now the logfunctions class has a
static field default_onoff[] which represents the default actions for
each kind of log message. Default_onoff[] is initialized with static
data so it should be valid by the time it's used. This can be reached by
static accesors logfunctions::set_default_action and
logfunctions::get_default_action. It seemed appropriate to put the defaults
inside the logfunctions class, rather than in bx_options or siminterface.
However, to make them accessible to the config interface, I added similar
methods in siminterface that map to the accessors in logfunctions.
- logio.cc had two different definitions of LOG_THIS for different halves
of the file, which was ugly and confusing. (LOG_THIS is needed for BX_INFO,
BX_DEBUG, etc.) I removed the first definition and fixed the minor compile
problems that ensued. In the initializers for iofunctions, everything
is complicated because of the unpredictable order that constructors get
called. They must use this->log to print things, because genlog hasn't
been initialized yet.
- now if SIM->set_log_action(int mod, int level, int action) is called
with mod<0, it sets the action for all modules/devices instead of just one.
- modified: bochs.h logio.cc main.cc gui/siminterface.cc gui/siminterface.h
- LogOptionsDialog: show the "no change" option. When options other than
"no change" are selected, set both the default log action and the
specific log action for all devices.
- AdvancedLogOptionsDialog: store the wxChoice*'s in a 2d array since I
have to refer to them later.
- since both the log options and advanced log options dialogs needed to
create many wxChoices using similar rules, I moved the creation code
into a utility function makeLogOptionChoiceBox.
- I finally discovered the wxADJUST_MINSIZE option to wxSizer::Add(),
which solves some layout problems that I was having with wxChoices.
With this setting, the wxChoice will automatically grow to the size of
the largest string that can be selected.
- improve sizing of the scrollWin according to the desired size of the panel
that contains all the wxChoices.
- add sketches for proposed dialog that combines both LogOptionsDialog and
AdvancedLogOptionsDialog using tabs

in cpu.cc out of the main loop, and into the asynchronous
events handling. I went through all the code paths, and
there doesn't seem to be any reason for that code to be
in the hot loop.
Added another accessor for getting instruction data, called
modC0(). A lot of instructions test whether the mod field
of mod-nnn-rm is 0xc0 or not, ie., it's a register operation
and not memory. So I flag this in fetchdecode{,64}.cc.
This added on the order of 1% performance improvement for
a Win95 boot.
Macroized a few leftover calls to Write_RMV_virtual_xyz()
that didn't get modified in the x86-64 merge. Really, they
just call the real function for now, but I want to have them
available to do direct writes with the guest2host TLB pointers.
but if you hand edit cpu/cpu.h, and change BxICacheEntries,
you can try different sizes. I'll make this more flexible
with configure. For now, use "--enable-icache" with no parameters.
- Modified fetchdecode.cc/fetchdecode64.cc just enough so that
instructions which encode a direct address now use a memory
resolution function which just sticks the immediate address
into rm_addr. With cached instructions we need this.
set_text_charbyte()
- vga: store the address of the active charmap in the new variable
charmap_address
- vga: text mode hack removed. The write modes, operations and masks must be
used in text mode too.
- sdl: clear_screen() is not necessary when the charmap has changed
- win32: update only the changed font bitmaps before drawing the text
- All mouse events in the VGA window go to MyPanel::OnMouse. Middle mouse
button and F12 both toggle mouse capture. OnMouse queues an event
for the simulation thread to process. The simulation thread calls
bx_devices.keyboard->mouse_motion() when it sees the event on the queue.
- add IFDBG_VGA around some display debug code. All wx mouse debug code
is controlled by IFDBG_MOUSE.
- modified: gui/wx.cc gui/wxmain.cc gui/wxmain.h
the wxwindows thread, it just sets a boolean flag needRefresh. Meanwhile, a
wxTimer running in wall clock time (as opposed to sim time) triggers a
repaint only if the the boolean is true.
- now MyRefresh is implemented by just setting needRefresh=true.
- make graphics_tile_update call MyRefresh.
- make dimension_update call MyRefresh.
to bitfields. bxInstruction_c is now 24 bytes, including 4 for
the memory addr resolution function pointer, and 4 for the
execution function pointer (16 + 4 + 4).
Coded more accessors, to abstract access from most code.
with accessors. Had to touch a number of files to update the
access using the new accessors.
Moved rm_addr to the CPU structure, to slim down bxInstruction_c
and to prevent future instruction caching from getting sprayed
with writes to individual rm_addr fields. There only needs to
be one. Though need to deal with instructions which have
static non-modrm addresses, but which are using rm_addr since
that will change.
bxInstruction_c is down to about 40 bytes now. Trying to
get down to 24 bytes.
read all param values from CPU #0. The only solution I can come up with
is to change the siminterface handler function interface to pass a void*
to the callback function. I'll take care of it eventually.
you can switch on and off using the $TEST_* varables at top.
- when running with --parallel, use "-geom +x+y" argument to xterm
to make the windows appear in a regular pattern.
use accessors. This lets me work on compressing the
size of fetch-decode structure (now called bxInstruction_c).
I've reduced it down to about 76 bytes. We should be able
to do much better soon. I needed the abstraction of the
accessors, so I have a lot of freedom to re-arrange things
without making massive future changes.
Lost a few percent of performance in these mods, but my
main focus was to get the abstraction.
