Summary: The changes in D59673 made the choice redundant, since we can achieve single-file split DWARF just by not setting an output file name. Like llc we can also derive whether to enable Split DWARF from whether -split-dwarf-file is set, so we don't need the flag at all anymore. The test CodeGen/split-debug-filename.c distinguished between having set or not set -enable-split-dwarf with -split-dwarf-file, but we can probably just always emit the metadata into the IR. The flag -split-dwarf wasn't used at all anymore. Reviewers: dblaikie, echristo Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D63167 llvm-svn: 364479
