[PATCH] D50685: [AArch64] Support conversion between fp16 and fp128

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: compiler-rt/lib/builtins/fp_extend.h:43
 #elif defined SRC_HALF
+#if defined __aarch64__ && defined __ARM_FP16_ARGS
+// Use __fp16 if available.
----------------
Can we implement this some other way?  _Float16 should have the right calling convention on all targets, I think.
