+==================== Branch dmf010, patch #1 ====================
+
+Rework 128-bit complex multiply and divide.
+
+This patch reworks how the complex multiply and divide built-in functions are
+done.  Previously GCC created built-in declarations for doing long double complex
+multiply and divide when long double is IEEE 128-bit.  However, it did not
+support __ibm128 complex multiply and divide if long double is IEEE 128-bit.
+
+This code does not create the built-in declaration with the changed name.
+Instead, it uses the TARGET_MANGLE_DECL_ASSEMBLER_NAME hook to change the name
+before it is written out to the assembler file like it now does for all of the
+other long double built-in functions.
