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