Any reason to not use relative line numbers?  See testsuite/gcc.dg/dg-test-1.c 
for a template for how to do it.  I think they should work and be better.  
Indeed, all line numbers should be relative, generally speaking.


FYI, I've written a script to convert all tests to relative line 
numbers. See PR80221 - "Contrib script to rewrite testcase from absolute 
to relative line numbers" ( 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80221 ).

Thanks,
