46 # Soft floating point options.
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.
