Ultimately it is failing because the code declared the > type to use TFmode but it used F128 functions (i.e. KFmode). Unfortunately, this patch no longer works against the trunk. I have a simpler patch to libgcc that uses the _Complex _Float128 and _Float128 types for building the IEEE 128-bit support in libgcc. It doesn't fix the problem in the compiler, but it will allow us to go forward and build GCC on targets that have IEEE 128-bit floating point support (i.e. Fedora 36). -- Michael Meissner, IBM PO Box 98, Ayer, Massachusetts, USA, 01432 email: meissner@linux.ibm.com
