I built llvm in MacOS (enabled "clang;lld;compiler-rt"), and saw the following error when opening compiler-rt/lib/profile/InstrProfilingFile.c. I only saw this kind of error in files under compiler-rt folder. For files under other folders like clang, llvm, lld, I don't see that and it works well.

can you provide full clangd logs ? they should contain the compile flags received from your database. it seems like you are compiling for multiple architectures within a single compilation, I don't know what clang flag triggers that though.

I added --log=verbose as clangd argument in vscode.

As I've suspected, you've got -arch i386 -arch x86_64 -arch arm64 in your compile flags which results in 3 compilation actions.
We should drop multiple arch options in clangd, but the question is which one to keep (or whether to keep any at all).

In the meantime you can workaround the issue by putting a .clangd file in your project root with contents:

CompileFlags:
  Remove: [-arch]

This will drop all -arch flags and make clang default to your host's architecture. If you want to edit code while targeting a specific architecture you can change contents to (while changing foo with your desired arch):

CompileFlags:
  Remove: [-arch]
  Add: [-arch, foo]

Thanks, that works.

Yeah exactly which is best is fuzzy (the example shows "first" isn't ideal), but clearly anything is better than what we do now.

BTW the easiest way to repro this on non-mac is adding a mac target (exact target doesn't matter).
compile_flags.txt:

--target=arm64e-apple-darwin20
-arch
i386
-arch
x86_64

[clangd] Avoid "expected one compiler job" by picking the first eligi…
2ff7ca9 
…ble job.

This happens in createInvocationWithCommandLine but only clangd currently passes
ShouldRecoverOnErorrs (sic).

One cause of this (with correct command) is several -arch arguments for mac
multi-arch support.

Fixes clangd/clangd#827

[clangd] Strip mutliple arch options
9350657 
This patch strips all the arch options in case of multiple ones. As it
results in multiple compiler jobs, which clangd cannot handle.

It doesn't pick any over the others as it is unclear which one the user wants
and defaulting to host architecture seems less surprising. Users also have the
ability to explicitly specify the architecture they want via clangd config
files.

Fixes clangd/clangd#827.
