freebsd-dev/lib/libc/softfloat/softfloat-for-gcc.h
David Schultz c36abe0dcf Merge in the latest SoftFloat changes from NetBSD. (NetBSD isn't the
original vendor, but we're using their heavily modified version.)
This brings in functions for long double emulation (both extended and
quad formats), which may be useful for testing, and also for replacing
libc/sparc64/fpu/.
