I do not know if FreeBSD has a uniform handling of experimental-status material in its LLVM. It might be that "incomplete feature" is no longer a thing in LLVM --so I'm not sure if the analogous question would even apply now. --=20 You are receiving this mail because: You are on the CC list for the bug.=
