<div>
<pre>Currently, when llvm-dwarfdump prints the debug line table with --verbose, any
DW_LNS_advance_line opcodes are printed as:
<offset>: 03 DW_LNS_advance_line (<new line value>)
I think this should be changed to:
<offset>: 03 DW_LNS_advance_line (<value to adjust by>)
This would be in keeping with the various operations that change the PC value,
e.g. DW_LNS_advance_pc, which print the value to adjust by.
This inconsistency can easily lead to confusion. Additionally, nothing really
is lost: the next time a line is emitted using e.g. DW_LNS_copy or a special
opcode, the new line value is printed there. Without this change, there is no
direct way of seeing what is actually written in the line program, which is the
point of verbose printing.</pre>
