Kumar Gala - Sept. 24, 2008, 4:05 a.m.
Move to using the generic math-emu code instead of PPC specific version.
Also cleaned up exception/error reporting from the FP emulation functions.

It seems _FP_DIV_MEAT_S() should be defined to
_FP_DIV_MEAT_1_udiv_norm().
I can't remember very clear, but it seems single point float need to be
normalized before calling udiv_qrnnd.

For now I'm leaving as it was in the old code.  We can submit fixes on  
top of this patch.

- * Basic four-word fraction declaration and manipulation.
- *
- * When adding quadword support for 32 bit machines, we need
- * to be a little careful as double multiply uses some of these
- * macros: (in op-2.h)
- * _FP_MUL_MEAT_2_wide() uses _FP_FRAC_DECL_4, _FP_FRAC_WORD_4,
- * _FP_FRAC_ADD_4, _FP_FRAC_SRS_4
- * _FP_MUL_MEAT_2_gmp() uses _FP_FRAC_SRS_4 (and should use
- * _FP_FRAC_DECL_4: it appears to be broken and is not used
- * anywhere anyway. )
- *
- * I've now fixed all the macros that were here from the sparc64 code.
- * [*none* of the shift macros were correct!] -- PMM 02/1998
- *
- * The only quadword stuff that remains to be coded is:
- * 1) the conversion to/from ints, which requires
- * that we check (in op-common.h) that the following do the right thing
- * for quadwords: _FP_TO_INT(Q,4,r,X,rsz,rsg), _FP_FROM_INT(Q,4,X,r,rs,rt)
- * 2) multiply, divide and sqrt, which require:
- * _FP_MUL_MEAT_4_*(R,X,Y), _FP_DIV_MEAT_4_*(R,X,Y), _FP_SQRT_MEAT_4(R,S,T,X,q),
- * This also needs _FP_MUL_MEAT_Q and _FP_DIV_MEAT_Q to be defined to
- * some suitable _FP_MUL_MEAT_4_* macros in sfp-machine.h.
- * [we're free to choose whatever FP_MUL_MEAT_4_* macros we need for
- * these; they are used nowhere else. ]
