Well, they would be if there wouldn't be strange code in 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.
