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.) -- Joseph S. Myers joseph@codesourcery.com
