Looks good to me!

clang/lib/Driver/ToolChains/AVR.cpp

Suggestion for the second sentence:

We directly use libclang.builtins.a as input file, instead of using '-lclang.builtins'.

I will change the comments in my commit. Thanks !

We started seeing test failures after this change on our bots. Would it be possible to revert the change and address these issues before relanding?

I have not a Fuchsia environment, I may do a try fix, reland, and check if my fix will be OK.

[benshi001]

@phosek ,

I have re-landed my patch, it seems the core reason is compiler-rt is default in Fuchsia environment, other than libgcc.

please inform me if it went wrong any longer.

Thanks, I'll keep on monitoring our builders. Another difference is that we use LLD as a the default linker. The solution we often use for other driver tests is setting --rtlib=platform and -fuse-ld=.
