supports it. This solves this error on the Darwin x86-64 platform:

}

5bda9e49ec Fix PR1666, SPASS with the CBE and 254.gap with the CBE.
GCC optimizes away things like ptr < NULL  to false.  To "fix" this,
have the CBE emit casts of pointers to intptr_t when doing relational
pointer comparisons.

9e3d3abd93 Remove the assumption that FP's are either float or
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.

dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).
