  47 # Notes:
  48 #   Currently builds with gcc 3.3 for arm, mips, mipsel, powerpc.
  49 #   (i386 support will be added back in at some point.)
  50 #   Only tested with multilib enabled.
  51 #   For i386, long double is the same as double (64 bits).  While this
  52 #      is unusual for x86, it seemed the best approach considering the
  53 #      limitations in the gcc floating point emulation library.
  54 #   For arm, soft float uses the usual libfloat routines.
  55 #   Custom specs files are used to set the default gcc mode to soft float
  56 #      as a convenience, since you shouldn't link hard and soft float
  57 #      together.  In fact, arm won't even let you.
