The GOFAST support is almost certainly unused and can probably be removed; 
at least, no-one has cared enough to fix the GOFAST case of bug 24998.  
(The relevant code to remove is I think the enable_gofast check in 
config.gcc, the documentation in doc/tm.texi, the file config/gofast.h, 
all the GOFAST conditionals in fp-bit.c and fp-bit.h, the effectively dead 
use of config/gofast.h and gofast_maybe_init_libfuncs in sparc/sparc.c, 
the comment in mips/elforion.h, the support in mips/mips.c, the file 
mips/t-gofast, and the use of US_SOFTWARE_GOFAST in mips/t-sr71k; the 
US_SOFTWARE_GOFAST macro can then be poisoned.)
