wxWindows without debugger, I needed to add some more cases of
#if BX_DEBUGGER to make it work. It is certainly possible to
handle such problems by always compiling in the debug dialogs but
only instantiating them if debug support is compiled in, but I have
chosen (for now) to put #if BX_DEBUGGER around things like this.

wxWindows without debugger, I needed to add some more cases of #if
BX_DEBUGGER to make it work. All the problems I found were things like
referencing a debug structure which was never initialized (NULL). It is
possible to handle such problems by always compiling in the debug dialogs but
only instantiating them if debug support is compiled in, but I have chosen
(for now) to put #if BX_DEBUGGER around things like this.
class declaration, for example:
static const unsigned os_64=0, as_64=0;
After reading some suggestions on usenet, I changed these into
enums instead, like this:
enum { os_64=0, as_64=0 };
you have AC_DEFINE(var, value) executed more than once, autoconf is
supposed to use the last AC_DEFINE value, but sometimes it doesn't.
I haven't been able to figure out why, so I've just worked around it
instead.
- for BX_SupportGlobalPages, which could call AC_DEFINE twice, I kept the
value in a shell variable $support_global_pages until the end and then
did one AC_DEFINE after it had reached its final value. Same thing
with BX_USE_CONFIG_INTERFACE.
- also I realized that we are using AC_SUBST() in many cases where it is
not needed. AC_SUBST(name) substitutes the string @name@ with a
value from the configure script. For preprocessor symbols like
BX_SupportPAE, we only need the AC_DEFINE; the AC_SUBST has no effect.
be used at all, and Peter didn't want it. "extdb.o" is compiled
into libcpu.a, if configured for it.
Removed a few #warnings for x86-64 compile, based on Peter's
line-item comments regarding the warnings I inserted during
the port/merge.
- try to find the configure script and set the path correctly, in case
the script is run from the main directory, build, etc.
- name the build directories build-$name so they don't overwrite anything.
Now that I have "rm -rf" in my script I wanted to be a little more careful.
printed to stderr in the text debugger. Also allows the user to
type (text) debugger commands directly, which also appear in the log.
- all text output in the debugger now passes through dbg_printf()
(used to be fprintf to stderr) so that in wxWindows I can redirect
it all to the wxWindows debug log screen. Added debug_fputs to
siminterface which actually sends the text to the GUI by creating
a BX_ASYNC_EVT_DBG_MSG event.
- changed prefix and msg fields of BxLogMsgEvent to const char *,
and also in args of logmsg method of siminterface.
- don't trap SIGINT in wxWindows. There are other ways to stop execution.
Also, signal handling with multiple threads is very strange and different
on different platforms.
- minor changes to fix gcc -Wall warnings in dbg_main.cc
- add a new boolean parameter BXP_DEBUG_RUNNING that tells if the debugger is
running freely or not. This is used by the wxWindows GUI to enable or
disable certain choices.
- CpuRegistersDialog has continue,stop,step buttons. When the sim is running
freely, I disable continue and step, and enable stop. When the sim stops
to wait for the user, I disable stop and enable continue and step. The
change of enables used to be triggered by actually pressing the button,
but then if you started/stopped the simulation in some other way (typing
in debug log window) the enables were never changed. Now the enables are
controlled by the value of BXP_DEBUG_RUNNING, which is set by the debug code
itself, and the buttons are enabled at the right time.
- ParamDialog::Refresh() is now virtual so that child classes can redefine
its refresh behavior.
- in safeWxStrcpy, force the last element of the array to be a 0, since
I noticed that strncpy is not guaranteed to terminate the string!

printing a message when a reserved bit was set, but not causing
a #GP(0). As well, I force a new PAE support option to 1 when
Hammer support is enabled.
circular dependencies between 3 cpu related libs that I need
as part of this transition. I changed the "ar rv" to "ld -i -o"
to do an incremental load instead of an archive. Hope this
doesn't break any platforms. We can reset this later.
at the appropriate times. For example, you can't stop when you're
stopped. You can't step when it's running.
