After removing this bit (forcing 128 long doubles for -m64) and making
long doubles 64bit for VxWorks, the following code
static int sizeof_long_double = sizeof(long double);
static int sizeof_unsigned_long_long = sizeof(unsigned long long);
int main (void)
long double X = 1.0;
unsigned long long V2 = (unsigned long long) (X);
still yields :
call _Qp_dtoq, 0
call _Qp_qtoux, 0
AFAICS, this is because expand_fix finds ...
"TARGET_FPU && TARGET_ARCH64 && ! TARGET_HARD_QUAD"
emit_library_call_value (gen_rtx (SYMBOL_REF, Pmode, \"_Qp_qtoux\"),
operands, 0, DImode, 1,
XEXP (slot0, 0), Pmode);
Unfortunately, the _Qp_ functions are not available on VxWorks.
Would there be a simple way to take this into account ?
Thanks in advance for your help,
