DSYMUTIL(1)                           LLVM                           DSYMUTIL(1)

       dsymutil - manipulate archived DWARF debug symbol files

       dsymutil [options] executable

       dsymutil links the DWARF debug information found in the object files for
       an executable executable by using debug symbols information contained in
       its symbol table. By default, the linked debug information is placed in a
       .dSYM bundle with the same name as the executable.


       --accelerator=<accelerator type>
              Specify the desired type of accelerator table. Valid options are
              'Apple', 'Dwarf' and 'Default'.

       --arch <arch>
              Link DWARF debug information only for specified CPU architecture
              types.  Architectures may be specified by name. When using this
              option, an error will be returned if any architectures can not be
              properly linked.  This option can be specified multiple times,
              once for each desired architecture. All CPU architectures will be
              linked by default and any architectures that can't be properly
              linked will cause dsymutil to return an error.

              Dump the executable's debug-map (the list of the object files
              containing the debug information) in YAML format and exit. Not
              DWARF link will take place.

       --flat, -f
              Produce a flat dSYM file. A .dwarf extension will be appended to
              the executable name unless the output file is specified using the
              -o option.

              Generate a reproducer consisting of the input object files.

       --help, -h
              Print this help output.

              Make a static variable keep the enclosing function even if it
              would have been omitted otherwise.

       --minimize, -z
              When used when creating a dSYM file, this option will suppress the
              emission of the .debug_inlines, .debug_pubnames, and
              .debug_pubtypes sections since dsymutil currently has better
              equivalents: .apple_names and .apple_types. When used in
              conjunction with --update option, this option will cause redundant
              accelerator tables to be removed.

              Do not use ODR (One Definition Rule) for uniquing C++ types.

              Do the link in memory, but do not emit the result file.

              Don't check the timestamp for swiftmodule files.

       --num-threads <threads>, -j <threads>
              Specifies the maximum number (n) of simultaneous threads to use
              when linking multiple architectures.

       --object-prefix-map <prefix=remapped>
              Remap object file paths (but no source paths) before processing.
              Use this for Clang objects where the module cache location was
              remapped using -fdebug-prefix-map; to help dsymutil find the Clang
              module cache.

       --oso-prepend-path <path>
              Specifies a path to prepend to all debug symbol object file paths.

       --out <filename>, -o <filename>
              Specifies an alternate path to place the dSYM bundle. The default
              dSYM bundle path is created by appending .dSYM to the executable

              When running dsymutil as part of your build system, it can be
              desirable for warnings to be part of the end product, rather than
              just being emitted to the output stream. When enabled warnings are
              embedded in the linked DWARF debug information.

       --remarks-output-format <format>
              Specify the format to be used when serializing the linked remarks.

       --remarks-prepend-path <path>
              Specify a directory to prepend the paths of the external remark

              Print statistics about the contribution of each object file to the
              linked debug info. This prints a table after linking with the
              object file name, the size of the debug info in the object file
              (in bytes) and the size contributed (in bytes) to the linked dSYM.
              The table is sorted by the output size listing the object files
              with the largest contribution first.

       --symbol-map <bcsymbolmap>
              Update the existing dSYMs inplace using symbol map specified.

       -s, --symtab
              Dumps the symbol table found in executable or object file(s) and

       -S     Output textual assembly instead of a binary dSYM companion file.

       --toolchain <toolchain>
              Embed the toolchain in the dSYM bundle's property list.

       -u, --update
              Update an existing dSYM file to contain the latest accelerator
              tables and other DWARF optimizations. This option will rebuild the
              '.apple_names' and '.apple_types' hashed accelerator tables.

       --use-reproducer <path>
              Use the object files from the given reproducer path.

              Display verbose information when linking.

              Run the DWARF verifier on the linked DWARF debug info.

       -v, --version
              Display the version of the tool.

       -y     Treat executable as a YAML debug-map rather than an executable.

       dsymutil returns 0 if the DWARF debug information was linked
       successfully. Otherwise, it returns 1.
