+==================== work097, patch007
+
+Add predicates to inter-mix 128-bit floating point modes.
+
+This patch adds two new predicates (ieee128_operand and ibm128_operand) that
+allow KFmode and TFmode to be used inter-changeably when long double is IEEE
+128-bit, and IFmode and TFmode to be used inter-changeabily with long double is
+IBM 128-bit.
+
+The various built-in functions that use KFmode or IFmode have been modified to
+use these new predicates.
+
+The code in rs6000_expand_builtin that switched between the KFmode and TFmode
+built-in functions and the code that switched between the IFmode and TFmode
+built-in functions has been modified so it looks at the argument type.  If a
+TFmode argument was passed, it will convert the built-in to from using KFmode or
+IFmode to one using TFmode.
+
+The nop conversion functions between IFmode and TFmode when long double uses IBM
+128-bit have been extended so that they take GPR registers as well as FPR
+registers.  This is to allow the test "pr105334.c" to pass.  This test wants to
+use -msoft-float along with the __ibm128 pack/unpack functions.

+==================== work097, patch005
+
+Improve converting between 128-bit modes that use the same format.
+
+This patch improves the insns used for converting between two modes using
+the 128-bit floating point format (i.e. converting between KFmode and TFmode if
+-mabi=ieeelongdouble is used, and converting between IFmode and TFmode if
+-mabi=ibmlongdouble is used).  The new insns have the correct insn type and
+instruction length for the move involved.
