6; Check that a difference between two symbols in the same fragment
7; causes relocations to be emitted if and only if relaxation is enabled.

9; This specific test is checking that the size of the function in
10; the debug information is represented by a relocation. This isn't
11; an assembly test as the assembler takes a different path through
12; LLVM, which is already covered by the fixups-expr.s test.
