            Bug ID: 25386
           Summary: Use split-dwarf opcodes without doing the splitting
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: echristo at gmail.com
          Reporter: tberghammer at google.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Add a new command line option to clang to enable the usage of the dwarf opcodes
currently used when compiling with split debug info (-gsplit-dwarf) without
enabling the splitting itself.

The purpose of this feature is to get the link time advantage of the new
opcodes (easier relocation) without generating a separate debug info file for
each object file what can slow down the download of the debug info from a
remote build machine.
