What steps will reproduce the bug?
Compiling Node.js with ClangCL eg. running vcbuild.bat clang-cl.
How often does it reproduce? Is there a required condition?
Always.
What is the expected behavior? Why is that the expected behavior?
I expect small, subtle differences between MSVC and ClangCL compilation time.
What do you see instead?
ClangCL compilation is ~2.5 slower (less with x64, more with ARM64).
Additional information
The main difference is that ClangCL doesn't use precompiled headers, which MSVC does. There might be others too.
