++     two integers to the FLO_union_type.

++; ??? This is all really a hack to get Dhrystone to work as fast as possible
++;     things to be fixed:
++;        * let the compiler core handle all of this, for that to work the extra
++;          aliasing needs to be addressed.
++;        * we use three temporary registers for loading and storing to ensure no
++;          ld use stalls, this is excessive, because after the first ld/st only
++;          two are needed. Only two would be needed all the way through if 
++;          we could schedule with other code. Consider:
++;           1  ld $1, 0($src)
++;           2  ld $2, 4($src)
++;           3  ld $3, 8($src)
++;           4  st $1, 0($dest)
++;           5  ld $1, 12($src)
++;           6  st $2, 4($src)
++;           7  etc.
++;          The first store has to wait until 4. If it does not there will be one
++;          cycle of stalling. However, if any other instruction could be placed
++;          between 1 and 4, $3 would not be needed.
++;        * In small we probably don't want to ever do this ourself because there
++;          is no ld use stall.

++##
++## 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

++@subsection Altera Nios II Built-in Functions
++
++These built-in functions are available for the Altera Nios II
++family of processors.
++
++The following built-in functions are always available.  They
++all generate the machine instruction that is part of the name.
++
++@example
++int __builtin_ldbio (volatile const void *)
++int __builtin_ldbuio (volatile const void *)
++int __builtin_ldhio (volatile const void *)
++int __builtin_ldhuio (volatile const void *)
++int __builtin_ldwio (volatile const void *)
++void __builtin_stbio (volatile void *, int)
++void __builtin_sthio (volatile void *, int)
++void __builtin_stwio (volatile void *, int)
++void __builtin_sync (void)
++int __builtin_rdctl (int) 
++void __builtin_wrctl (int, int)
++@end example
++
++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
++
++@item f
++@code{float} for return type and parameter type
++
++@item p
++@code{void *} for return type and parameter type
++

+# Submitted:
+#
+# Dimitry Andric <dimitry@andric.com>, 2004-05-01
+#
+# Description:
+#
+# Nicholas Pitre released this patch for gcc soft-float support here: 
+# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
+#
+# This version has been adapted to work with gcc 3.4.0.
+#
+# The original patch doesn't distinguish between softfpa and softvfp modes
+# in the way Nicholas Pitre probably meant.  His description is:
+#
+# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
+# floats can be achieved with -mhard-float or with the configure
+# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
+# software float support will be used just like the default but with the legacy
+# big endian word ordering for double float representation instead."
+#
+# Which means the following:
+#
+# * If you compile without -mhard-float or -msoft-float, you should get
+#   software floating point, using the VFP format.  The produced object file
+#   should have these flags in its header:
+#
+#     private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+# * If you compile with -mhard-float, you should get hardware floating point,
+#   which always uses the FPA format.  Object file header flags should be:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+# * If you compile with -msoft-float, you should get software floating point,
+#   using the FPA format.  This is done for compatibility reasons with many
+#   existing distributions.  Object file header flags should be:
+#
+#     private flags = 200: [APCS-32] [FPA float format] [software FP]
+#
+# The original patch from Nicholas Pitre contained the following constructs:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
+#
+# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
+# is probably the reason Robert Schwebel modified it to:
+#
+#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
+#     %{mhard-float:-mfpu=fpa} \
+#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
+#
+# But this causes the following behaviour:
+#
+# * If you compile without -mhard-float or -msoft-float, the compiler generates
+#   software floating point instructions, but *nothing* is passed to the
+#   assembler, which results in an object file which has flags:
+#
+#     private flags = 0: [APCS-32] [FPA float format]
+#
+#   This is not correct!
+#
+# * If you compile with -mhard-float, the compiler generates hardware floating
+#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
+#   in an object file which has the same flags as in the previous item, but now
+#   those *are* correct.
+#    
+# * If you compile with -msoft-float, the compiler generates software floating
+#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
+#   order) to the assembler, which results in an object file with flags:
+#
+#   private flags = 600: [APCS-32] [VFP float format] [software FP]
+#
+#   This is not correct, because the last "-mfpu=" option on the assembler
+#   command line determines the actual FPU convention used (which should be FPA
+#   in this case).
+#
+# Therefore, I modified this patch to get the desired behaviour.  Every
+# instance of the notation:
+#
+#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
+#
+# was changed to:
+#
+#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
+#
+# I also did the following:
+# 
+# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
+#   be consistent with Nicholas' original patch.
+# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
+#   macros I could find.  I think that if you compile without any options, you
+#   would like to get the defaults. :)
+# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
+#   anymore.  (The required functions are now in libgcc.)
