Re: [edk2-devel] [PATCH 3/9] BaseTools: Update CLANGDWARF toolchain and remove CLANG35 and CLANG38

["Rebecca Cran" <rebecca@bsdio.com>]

I'm not seeing this failure. Could you tell me what the following 
commands print, please:


where clang

where lld


Mine are:


C:\Users\bcran\Documents\src\uefi\edk2>where clang
C:\Program Files\LLVM\bin\clang.exe
C:\Program Files (x86)\Microsoft Visual 
Studio\2019\Professional\VC\Tools\Llvm\bin\clang.exe

C:\Users\bcran\Documents\src\uefi\edk2>where lld
C:\Program Files\LLVM\bin\lld.exe
C:\Program Files (x86)\Microsoft Visual 
Studio\2019\Professional\VC\Tools\Llvm\bin\lld.exe


Also, could you provide more of the output?
