Subject: RE: [PATCH] UnitTestFrameworkPkg: Add code coverage support for GCC

Hi,

This change looks safe because it is scoped to host-based unit tests that 
include this file in the DSC file that builds host-based tests.

Can you also update the UnitTestFrameworkPkg/ReadMe.md to describe how a 
developer can enable/use the code coverage feature for GCC host-based tests?

Mike
