Andrew:
  Yes. This method can create the same size image. For your proposal, when 
compiler source file, its related file path will be used, right? If yes, its 
command must run at $WORKSAPCE directory?

Thanks

Subject: [edk2-buildtools] Request to add $(relsrc) support to 
build_rule.template

We would like to have the option of the ASSERT() messages being $WORKSPACE 
relative. This makes them not only small, but also a standard size.  It removes 
the need to map a drive (on Windows) or make symlinks (Unix) to try and control 
the length of the ASSERT messages.  I could not think of a way to make this 
work so I ended up adding $(relsrc) support to the build_rule.template file.

I had to make the following change to add this feature. I'm thinking there may 
be an easier way to access $(WORKSPACE), but I was not sure how to do this?

If there is interest in making this change I can create a patch. If there is a 
better way to do this please let me know.
