The latest commit 4cb0b7ce <https://reviews.llvm.org/rG4cb0b7ce3b4987446264312d582dac9c9a98a488> fixed the 'formatv' error, but now there is a different error:

With VS2019, Microsoft (R) C/C++ Optimizing Compiler Version 19.29.30148 for x64

C:\j\w\779ddbee\p\llvm\include\llvm/Support/Endian.h(202): note: or       'llvm::support::detail'

This error is the key to these problem. There are two namespace named 'details', llvm::details and llvm::support::details. Adding 'using namespace support' introduces both at the same level, so details:: becomes ambiguous.
