type simply is double itself, and hence these functions are unused

arm-gen.c that makes use of xfdi conversions when VFP is enabled.
That makes no sense, also with VFP there's only support for IEEE
double, not for extended double.
Since LDOUBLE_SIZE == 8 on VFP, those code lines will only be used with FPA.
And there they won't either because LDOUBLE_SIZE is also 8 for !VFP.
That's what I meant with "strange" I guess, it's dead code :)
Ciao,
Michael.
