/* Output floating point type values used by the 'R' stab letter.
These numbers come from include/aout/stab_gnu.h in binutils/gdb.
There are only 3 real/complex types defined, and we need 7/6.
We use NF_SINGLE as a generic float type, and NF_COMPLEX as a generic
complex type. Since we have the type size anyways, we don't really need
to distinguish between different FP types, we only need to distinguish
between float and complex. This works fine with gdb.
We only use this for complex types, to avoid breaking backwards
compatibility for real types. complex types aren't in ISO C90, so it is
OK if old debuggers don't understand the debug info we emit for them. */
