# commit 603e84104cdc709c8e7dcbac54b9a585bf8dff78

#     PowerPC floating point little-endian [9 of 15]

#     http://sourceware.org/ml/libc-alpha/2013-07/msg00200.html

#     

#     This works around the fact that vsx is disabled in current

#     little-endian gcc.  Also, float constants take 4 bytes in memory

#     vs. 16 bytes for vector constants, and we don't need to write one lot

#     of masks for double (register format) and another for float (mem

#     format).

#     

#         * sysdeps/powerpc/fpu/s_float_bitwise.h (__float_and_test28): Don't

#         use vector int constants.

#         (__float_and_test24, __float_and8, __float_get_exp): Likewise.
