Example to reproduce

Hi!
I'm using Clang/LLD v10.0.0-rc2 on Windows to collect code coverage report
(please find attached example).

I need to eliminate all unused functions from produced binary. I use /OPC:REF
linker option for this but it doesn't help if -fprofile-instr-generate compiler
option is used. If I remove -fprofile-instr-generate unused functions are
discarded.
