+
+PR target/107299: Update IEEE 128-bit types for PowerPC libgcc

+This patch updates the IEEE 128-bit types in libgcc.
+
+At the moment, we cannot build GCC when the target uses IEEE 128-bit long
+doubles, such as building the compiler for a native Fedora 36 system. The
+build dies when it is trying to build the _mulkc3.c and _divkc3 modules.

+This patch changes the IEEE 128-bit type (TFtype) in the IEEE 128-bit support
+to use either _Float128 or long double. Previously we would use the __float128
+type. In addition, the TCtype will use the same type along with _Complex.
+
+I changed the libgcc build so that the IEEE 128-bit support is now compiled
+with -mabi=ieeelongdouble. For the _mulkc3 and _divkc3, I explicitly use long
+double and long double _Complex to avoid type mismatch errors.
+
+While it is desirable to ultimately have __float128 and _Float128 use the same
+internal type and mode within GCC, at present if you use the option
+-mabi=ieeelongdouble, the __float128 type will use the long double type. We
+get an internal compiler error if we combine the signbitf128 built-in with a
+long double type.

+I've gone through several iterations of trying to fix this within GCC, and
+there are various problems that have come up. I developed this alternative
+patch that changes libgcc so that it does not tickle the issue. I hope we can
+fix the compiler at some point, but right now, this is preventing people on
+Fedora 36 systems from building compilers where the default long double is IEEE
+128-bit.
