+// Only the hard-float ABI on Sparc is standardized, and it is the
+// default. GCC also supports a nonstandard soft-float ABI mode, and
+// perhaps LLVM should implement that, too. However, since llvm
+// currently does not support Sparc soft-float, at all, display an

It is. I assume by that comment you mean that you would prefer it removed.
