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.
- use Bit64u and other compiler-independent types
- moved contents of macutils.* into osdep.*.
- now in osdep.h, I allow all code to use the real library function name.
If that function is not available, #define it to point to the
bx_* replacement function instead. And cause the bx_* replacement
function to be compiled in osdep.cc.
- 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
didn't compile with some compiler.
- put conditional "#if BX_HAVE_HASH_MAP" around code that uses
<hash_map.h>.
- replace calls to snprintf with bx_snprintf.
- arg1 of bx_dbg_watch is an int, not a Boolean.
- put /*comments symbols*/ around any chars after #endif. Other compilers
do not get it.
- fix cases in which a pointer is cast to a 32-bit int, then back to a
pointer. This breaks on a machine with 64-bit pointers. Examples:
FPU_sub arg 2 and FPU_div arg 2. The int->ptr->int conversions are
now done more safely by macros REGNO2PTR and PTR2INT.
- use GCC_ATTRIBUTE macro instead of __attribute__. For compilers that
do not support __attribute__, the macro can be defined to be nothing.
- in fpu_entry.c, arg1 of FPU_load_int32 is (s32*), but the calls to
it cast their data to (u32*).
- if compiler does NOT inline functions in poly.h, the "extern inline"
setting caused duplicate symbols to be created. Changed them to
"static inline" so that the mul_32_32 from different .c files do not
conflict.
- implemented setcc so that it doesn't use curly brackets inside parens
- comment out sigcontext structure definition, which conflicts with
non-linux or non-intel operating systems. It's not used by bochs anyway.
