This eliminates the checked-in .clangd file at the root of the engine repository, which gets picked up by editors that rely on clangd. In particular, the Remove: [-m*, -f*] is problematic for iOS/macOS embedder developers since it removes the -fobjc-arc flag, which causes clangd to emit errors when using ARC features. Example:

Cannot create __weak reference in file using manual reference counting

This removes the checked-in file, and instead writes the file before running the test, then cleans it up afterwards. Unfortunately, clangd does not appear to have a mechanism to point to a config file elsewhere and run as though it were present in a specified directory.

Fixes: flutter/flutter#154064

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Requested a test exemption because this is a test. As noted in the chat, we should probably add this to the excluded paths in the bot.

Update: I sent a PR for that: flutter/cocoon#3874

This eliminates the checked-in `.clangd` file at the root of the engine
repository, which gets picked up by editors that rely on `clangd`. In
particular, the `Remove: [-m*, -f*]` is problematic for iOS/macOS
embedder developers since it removes the `-fobjc-arc` flag, which causes
`clangd` to emit errors when using ARC features. Example:

   Cannot create __weak reference in file using manual reference counting

This removes the checked-in file, and instead writes the file before
running the test, then cleans it up afterwards. Unfortunately, `clangd`
does not appear to have a mechanism to point to a config file elsewhere
and run as though it were present in a specified directory.
