[llvm-dev] [RFC] - Deduplication of debug information in linkers (LLD).

So instead of splitting debug info into separate files, info could be still included into linker output.
?>But difference with current traditional flow is that linker would not process debug relocations
>(because technically info can be (probably) close/the same as split debug has), what could (probably)

Ok. That above looks sound wierd. I think I just need to read more about how all DWARF things work then.
(particularry about split debug output details and dsymutil, though their logic looks transparent for me atm).
Or that brief description I mentioned I saw somewhere was dead
from start or it most likely it was just something else/different suggested, probably with involving
a compiler/debugger side changes too as well. Can only guess now :/

George.
