PowerPC floating point little-endian [12 of 15]
http://sourceware.org/ml/libc-alpha/2013-08/msg00087.html Fixes for little-endian in 32-bit assembly. * sysdeps/powerpc/sysdep.h (LOWORD, HIWORD, HISHORT): Define. * sysdeps/powerpc/powerpc32/fpu/s_copysign.S: Load little-endian words of double from correct stack offsets. * sysdeps/powerpc/powerpc32/fpu/s_copysignl.S: Likewise. * sysdeps/powerpc/powerpc32/fpu/s_lrint.S: Likewise. * sysdeps/powerpc/powerpc32/fpu/s_lround.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/s_llrint.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/s_llrintf.S: Likewise. * sysdeps/powerpc/powerpc32/power5+/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc32/power5+/fpu/s_lround.S: Likewise. * sysdeps/powerpc/powerpc32/power5/fpu/s_isnan.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_isnan.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_llrint.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_llrintf.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc32/power7/fpu/s_finite.S: Likewise. * sysdeps/powerpc/powerpc32/power7/fpu/s_isinf.S: Likewise. * sysdeps/powerpc/powerpc32/power7/fpu/s_isnan.S: Likewise. * sysdeps/powerpc/powerpc64/power7/fpu/s_finite.S: Use HISHORT. * sysdeps/powerpc/powerpc64/power7/fpu/s_isinf.S: Likewise.
