what action to take on panic, error, info, and debug. The lines don't
have any effect quite yet because of an initialization order problem
with the logfunctions.
signal. First, selection of the GUI should cause BX_GUI_SIGHANDLER to
be defined in config.h.in. Then, the GUI should define member functions
Bit32u get_sighandler_mask ();
void sighandler (int sig);
The mask function returns a bitfield where one bit corresponds to each
signal. For any signal whose bit is set to 1 in the return value of
get_sighandler_mask, the gui will control that signal. When the signal
arrives, bx_gui.sighandler(sig) will be called by bx_signal_handler,
instead of the default behavior of that signal.
For compilers (such as Microsoft VC++) which don't allow "LL" after a
constant to make it 64-bit, this patch declares all such constants as
BX_CONST64(value). Then in config.in, a switch called
BX_64BIT_CONSTANTS_USE_LL controls whether the macro puts the
LL's in or not. Configure sets the macro, if you're on a platform
that can run such things.
- check for snprintf, strtoull
- check if empty structs allowed
- check for hash_map.h
- check for blank labels as in void main () { int x=2; label: }
- if debugger, turn on disasm too
