Yes, all known and agreed upon.
* Finally, arm-gen.c uses TOK___fixxfdi with yet another #if condition =>
LDOUBLE_SIZE != 8
#if LDOUBLE_SIZE != 8
else if(r2 == VT_LDOUBLE)
func=TOK___fixxfdi;
else if(r2 == VT_DOUBLE)
#else
So there is at least one combination of compiler/pre-processor options on
ARM that may use __fixunsxfdi with a test on a uninitialized value.
LDOUBLE_SIZE != 8 is not possible in any arm config, so the function won't
be actually used at runtime. That's why your ifdef-ing out of these
functions in libtcc1.c is fine, and it is what we suggested all along.
(The dead code above should also be cleaned up to not cause further
confusion).
But _read what I write_: you have also disabled some dfdi routines at the
same time in your patch, not only the xfdi ones. _That_ is the problem,
you have ifdef-ed out other unrelated routines.
Ciao,
Michael.
