unfortunately is the same as the C library function fabs. Many
compilers seem to use the static one with no complaint, but others
don't like it. Just rename fabs, to eliminate the potential
conflict.
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.
- 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.
