- _Float16 is now accepted by Clang. - The half IR type is fully handled by the backend. - These values are passed in FP registers and converted to/from float around each operation. - Compiler-rt conversion functions are now built for s390x including the missing extendhfdf2 which was added. Fixes #50374
