34 # For floating-point emulation, we mostly use hand-coded assembly.
35 # We use fp-bit.c for debugging purposes, and some parts of it
36 # as a fallback for hardware configurations for which the hand-coded
37 # assembly support is incomplete, i.e., where there is no NORM and/or no
38 # supported multiply instruction. Using floating point on such a
39 # configuration is generally inadvisable, but we got to provide support
40 # somehow so that we can run the testsuites.
41 # fp-hack.h / dp-hack.h take care of slecting the parts that are needed,
42 # and (for debugging) of renaming functions so that they can be
43 # used in an asm wrapper.
