not define __FreeBSD__ ?

It seems that llvm16 in ports does not define __FreeBSD__.sys/timex.h used it.
Is it because I don't know how to use it? I'm trying to generate the loongarch code.
 
Seems to work for me.

Base version:
Code: 
$ echo | clang -dM -E - | grep -i freebsd
#define __FreeBSD__ 15
#define __FreeBSD_cc_version 1500000
#define __VERSION__ "FreeBSD Clang 16.0.6 (https://github.com/llvm/llvm-project.git llvmorg-16.0.6-0-g7cbf1a259152)"
llvm16 (16.0.6_6) from packages:
Code: 
$ echo | /usr/local/bin/clang16 -dM -E - | grep -i freebsd
#define __FreeBSD__ 15
#define __FreeBSD_cc_version 1500001

How do you check?

I change 4 files, and it work.
Code: 
lib/clang/include/llvm/Config/Targets.def
lib/clang/include/llvm/Config/AsmParsers.def
lib/clang/include/llvm/Config/Disassemblers.def
lib/clang/include/llvm/Config/AsmPrinters.def
