+# Author: Alan Modra <amodra@gmail.com>
+# Date: Sat Aug 17 18:21:58 2013 +0930

+# 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.
