So, any LEB128 number is counted as 5 byte long. Then, that "virtual bytecode offset" should exactly match the original, uncompressed byte code offset, eliminating the need of adjusting any byte offset in DWARF.


Yes, that's a valid solution too -- we just need to specify a normalized form that every debugger will consider when it will decode the data. Thanks. I had also idea to supply "code transform" custom sections that reflex the same idea, but without a burden for debugger to know about normalized "virtual bytecode offset" format.
