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.
--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-debug-map 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. -f, --flat 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. -z, --minimize 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. --no-odr Do not use ODR (One Definition Rule) for uniquing C++ types. --no-output Do the link in memory, but do not emit the result file. --no-swiftmodule-timestamp Don’t check the timestamp for swiftmodule files. -j <n>, --num-threads=<n> Specifies the maximum number (n) of simultaneous threads to use when linking multiple architectures. -o <filename> Specifies an alternate path to place the dSYM bundle. The default dSYM bundle path is created by appending .dSYM to the executable name. --oso-prepend-path=<path> Specifies a path to prepend to all debug symbol object file paths. --papertrail 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. -s, --symtab Dumps the symbol table found in executable or object file(s) and exits. --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. -v, --verbose Display verbose information when linking. --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.
