Yes, only 32bit code emits calls to this function, on both Windows and
Linux. The function is defined in either libgcc.a or libtcc1.a which
TCC automatically should link against (either of them). Somehow this is
not happening, I can't say why, you'll have to figure it out.
Alternatively, if there are reasons why you don't link against libtcc1.a
or libgcc.a you will have to provide an implementation of this function
yourself, you could look into lib/libtcc1.c source for that.
There are other helper functions that TCC might also generate calls for
in the i386 backend:
__divdi3 long ret,x,y; ret = x / y;
__udivdi3 ulong ret,x,y; ret = x / y;
__moddi3 long ret,x,y; ret = x % y;
__umoddi3 ulong ret,x,y; ret = x % y;
__ashrdi3 long ret,x,y; ret = x >> y;
__lshrdi3 ulong ret,x,y; ret = x >> y;
__floatundisf ulong -> float
__floatundidf ulong -> double
__floatundixf ulong -> long double
__fixunssfdi float -> ulong
__fixunsdfdi double -> ulong
__fixunsxfdi long double -> ulong
__fixsfdi float -> long
__fixdfdi double -> long
__fixxfdi long double -> long
So it's probably easier to just figure out why libtcc1.a isn't linked
automatically with your program.
Ciao,
Michael.
