+@item Floating Point Emulation
+To have GCC include software floating point libraries in @file{libgcc.a}
+define @code{FPBIT} and @code{DPBIT} along with a few rules as follows:
+@smallexample
+# We want fine grained libraries, so use the new code to build the
+# floating point emulation libraries.
+FPBIT = fp-bit.c
+DPBIT = dp-bit.c
+
+
+fp-bit.c: $(srcdir)/config/fp-bit.c
+ echo '#define FLOAT' > fp-bit.c
+ cat $(srcdir)/config/fp-bit.c >> fp-bit.c
+
+dp-bit.c: $(srcdir)/config/fp-bit.c
+ cat $(srcdir)/config/fp-bit.c > dp-bit.c
+@end smallexample
+
+You may need to provide additional #defines at the beginning of @file{fp-bit.c}
+and @file{dp-bit.c} to control target endianness and other options.
