With this version, the fp16 values are passed to conversion functions as integer, which seems to be the default. It is however a bit tricky to do this and at the same time pass half values in FP registers. At this point I wonder for one thing if it would be better to pass FP16 values to the conversion functions as _Float16 instead? It seems this may be possible to change in the configurations by looking at COMPILER_RT_HAS_FLOAT16 / compiler-rt/lib/builtins/extendhfsf2.c / fp_extend.h... Not really sure if those conversion functions are supposed to be built and only used for soft-promotion of fp16, or if there are any external implications, for instance gcc compatability. Any other comments also welcome... https://github.com/llvm/llvm-project/pull/109164 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
