Hi! Another question: Compiling a nimrod compiler by i386-win-tcc I
got the following error:
/usr/local/lib/win32/include/math.h:541: error: invalid clobber register
'st'
Go into include/math.h:541:
__CRT_INLINE long __cdecl lrint (double x)
{
long retval;
__asm__ __volatile__ \
("fistpl %0" : "=m" (retval) : "t" (x) : "st"); \
return retval;
}
__asm__ __volatile__("Instruction List" : Output : Input : Clobber/Modify);
