-+ FLOAT_ONLY: Used with FLOAT, to implement a `float' only library, i.e.
-+ don't include float->double conversion which requires the double library.
-+ This is useful only for machines which can't support doubles, e.g. some
-+ 8-bit processors.
-+ CMPtype: Specify the type that floating point compares should return.
-+ This defaults to SItype, aka int.
-+ US_SOFTWARE_GOFAST: This makes all entry points use the same names as the
-+ US Software goFast library.
-+ _DEBUG_BITFLOAT: This makes debugging the code a little easier, by adding
-+ two integers to the FLO_union_type.
-+ NO_DENORMALS: Disable handling of denormals.
-+ NO_NANS: Disable nan and infinity handling
-+ SMALL_MACHINE: Useful when operations on QIs and HIs are faster
-+ than on an SI */

-+/* We don't currently support extended floats (long doubles) on machines
-+ without hardware to deal with them.
-+
-+ These stubs are just to keep the linker from complaining about unresolved
-+ references which can be pulled in from libio & libstdc++, even if the
-+ user isn't using long doubles. However, they may generate an unresolved
-+ external to abort if abort is not used by the function, and the stubs

-+ FLOAT_ONLY: Used with FLOAT, to implement a `float' only library, i.e.
-+ don't include float->double conversion which requires the double library.
-+ This is useful only for machines which can't support doubles, e.g. some
-+ 8-bit processors.
-+ CMPtype: Specify the type that floating point compares should return.
-+ This defaults to SItype, aka int.
-+ US_SOFTWARE_GOFAST: This makes all entry points use the same names as the
-+ US Software goFast library.
-+ _DEBUG_BITFLOAT: This makes debugging the code a little easier, by adding
-+ two integers to the FLO_union_type.
-+ NO_DENORMALS: Disable handling of denormals.

-+## MULTILIB_OPTIONS
-+## For some targets, invoking GCC in different ways produces objects that
-+## can not be linked together. For example, for some targets GCC produces
-+## both big and little endian code. For these targets, you must arrange
-+## for multiple versions of libgcc.a to be compiled, one for each set of
-+## incompatible options. When GCC invokes the linker, it arranges to link
-+## in the right version of libgcc.a, based on the command line options
-+## used.
-+## The MULTILIB_OPTIONS macro lists the set of options for which special
-+## versions of libgcc.a must be built. Write options that are mutually
-+## incompatible side by side, separated by a slash. Write options that may
-+## be used together separated by a space. The build procedure will build
-+## all combinations of compatible options.
-+##
-+## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
-+## Makefile will build special versions of libgcc.a using the following
-+## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
-+## and -m68020 -msoft-float.
-+
-+MULTILIB_OPTIONS = mno-hw-mul mhw-mulx
-+
-+## MULTILIB_DIRNAMES
-+## If MULTILIB_OPTIONS is used, this variable specifies the directory names
-+## that should be used to hold the various libraries. Write one element in
-+## MULTILIB_DIRNAMES for each element in MULTILIB_OPTIONS. If
-+## MULTILIB_DIRNAMES is not used, the default value will be
-+## MULTILIB_OPTIONS, with all slashes treated as spaces.
-+## For example, if MULTILIB_OPTIONS is set to m68000/m68020 msoft-float,
-+## then the default value of MULTILIB_DIRNAMES is m68000 m68020
-+## msoft-float. You may specify a different value if you desire a
-+## different set of directory names.
-+
-+# MULTILIB_DIRNAMES =
-+
-+## MULTILIB_MATCHES
-+## Sometimes the same option may be written in two different ways. If an
-+## option is listed in MULTILIB_OPTIONS, GCC needs to know about any
-+## synonyms. In that case, set MULTILIB_MATCHES to a list of items of the
-+## form option=option to describe all relevant synonyms. For example,
-+## m68000=mc68000 m68020=mc68020.
-+##
-+## MULTILIB_EXCEPTIONS
-+## Sometimes when there are multiple sets of MULTILIB_OPTIONS being
-+## specified, there are combinations that should not be built. In that
-+## case, set MULTILIB_EXCEPTIONS to be all of the switch exceptions in
-+## shell case syntax that should not be built.
-+## For example, in the PowerPC embedded ABI support, it is not desirable to
-+## build libraries compiled with the -mcall-aix option and either of the
-+## -fleading-underscore or -mlittle options at the same time. Therefore
-+## MULTILIB_EXCEPTIONS is set to
-+##
-+## *mcall-aix/*fleading-underscore* *mlittle/*mcall-aix*
-+##
-+
-+MULTILIB_EXCEPTIONS = *mno-hw-mul/*mhw-mulx*
-+
-+##
-+## MULTILIB_EXTRA_OPTS Sometimes it is desirable that when building
-+## multiple versions of libgcc.a certain options should always be passed on
-+## to the compiler. In that case, set MULTILIB_EXTRA_OPTS to be the list
-+## of options to be used for all builds.

-+
-+The following built-in functions are always available. They
-+all generate a Nios II Custom Instruction. The name of the
-+function represents the types that the function takes and
-+returns. The letter before the @code{n} is the return type
-+or void if absent. The @code{n} represnts the first parameter
-+to all the custom instructions, the custom instruction number.
-+The two letters after the @code{n} represent the up to two
-+parameters to the function.
-+
-+The letters reprsent the following data types:
-+@table @code
-+@item <no letter>
-+@code{void} for return type and no parameter for parameter types.
-+
-+@item i
-+@code{int} for return type and parameter type

-+@code{float} for return type and parameter type

-+Integer that is valid as an immediate operand for

-+the format modifier @code{z} to use @code{r0}
-+instead of @code{0} in the assembly output.

-+Integer that is valid as an immediate operand for

-+@item S
-+Matches immediates which are addresses in the small

-+as a 16-bit immediate to re-create their 32-bit value.
