           Summary: llvm-cov: Coverage summary shows coverage of
                    instantiations even with -show-expansions=0

Created attachment 19015

Main cpp file, expect 100% line and region coverage here

When creating an html report using llvm-cov show -format html
-show-instantiations=0 -show-expansions=0, the summary html file still shows a
lower line and region coverage for files containing a macro expansion. I would
expect 100% line and region coverage for that file since we explicitly told
llvm-cov that we don't care about expansions.
