OVERVIEW: merge split dwarf (.dwo) files

USAGE: llvm-dwp [options] <input files>

OPTIONS:
  -continue-on-cu-index-overflow=<value>
                default = continue, This turns an error when offset
                		for .debug_*.dwo sections overfolws into a warning. = soft-stop, This produces a
                		truncated but valid DWP file, discarding any DWO files that would not fit within
                		the 32 bit/4GB limits of the format.
  -dwarf64-str-offsets-promotion=<value>
                default = enabled, This allows .debug_str tables to exceed the 4GB limit
                and have any DWARF32 .debug_str_offsets tables converted to DWARF64 only for tables
                that require 64 bit string offsets. = disabled, This setting doesn't convert DWARF32
                .debug_str_offsets tables in .dwo files to DWARF64 in the .dwp file. = always, This
                forces all .debug_str_offsets tables to be emitted as DWARF64. This is used for testing.
  -e <filename> Specify the executable/library files to get the list of *.dwo from.
  -help         Display this help
  -h            Alias for --help
  -o <filename> Specify the output file.
