Can you please clarify what needs to be tested using .s files?
I think you want me to test that
llc -filetype=asm | llvm-mc -filetype=obj
generates the same file as
does for the new directives emitted by EmitCOFFSectionReference and
EmitCOFFStaticOffset (namely ".secrel32" and ".offset from L1 to L2").
Just wanted to double-check that I understood you correctly.
