Alan Modra 1b6adf888d PowerPC floating point little-endian [1 of 15] ... http://sourceware.org/ml/libc-alpha/2013-08/msg00081.html This is the first of a series of patches to ban ieee854_long_double and the ieee854_long_double macros when using IBM long double. union ieee854_long_double just isn't correct for IBM long double, especially when little-endian, and pretending it is OK has allowed a number of bugs to remain undetected in sysdeps/ieee754/ldbl-128ibm/. This changes the few places in generic code that use it. * stdio-common/printf_size.c (__printf_size): Don't use union ieee854_long_double in fpnum union. * stdio-common/printf_fphex.c (__printf_fphex): Likewise. Use signbit macro to retrieve sign from long double. * stdio-common/printf_fp.c (___printf_fp): Use signbit macro to retrieve sign from long double. * sysdeps/ieee754/ldbl-128ibm/printf_fphex.c: Adjust for fpnum change. * sysdeps/ieee754/ldbl-128/printf_fphex.c: Likewise. * sysdeps/ieee754/ldbl-96/printf_fphex.c: Likewise. * sysdeps/x86_64/fpu/printf_fphex.c: Likewise. * math/test-misc.c (main): Don't use union ieee854_long_double. ports/ * sysdeps/ia64/fpu/printf_fphex.c: Adjust for fpnum change.		2013-10-04 10:31:41 +09:30
