Well, soft-fp is used in libgcc for x86/x86_64 for __float128 support, for 
example, and in the Linux kernel on various architectures both for 
emulation on soft-float processors and to handle traps to the kernel on 
processors where some floating-point cases are handled in hardware but 
various special cases trap to software - the feature this particular patch 
adds is used in the kernel for Alpha (see 
<> regarding the 
desire to resync the kernel with glibc soft-fp again).  (Some 
architectures have their own floating-point emulation implementations in 
the kernel for whatever reason, rather than using soft-fp.)
