Note... modified my mjn3 to not conflict with the big endian arm patch.
Warning!!!  Only the linux target is aware of TARGET_ENDIAN_DEFAULT.

# 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.)
