NAME
llvm-dsymutil - manipulate archived DWARF debug symbol files.
SYNOPSIS
llvm-dsymutil [options] exe_file llvm-dsymutil <i>asymbol-map=bcsymbolmap [options] exe_file
DESCRIPTION
llvm-dsymutil links the DWARF debug information found in the object files for an executable exe_file by using debug symbols information contained in its symbol table.
OPTIONS
-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 architec- tures will be linked by default and any architectures that canat be properly linked will cause llvm-dsymutil to return an error. -f, --flat Produce a flat dSYM file. A a.dwarfa extension will be appended to the executable name unless the output file is specified using the -o option. -o path, --out=path Specifies an alternate path to place the .dSYM bundle. The default dSYM bundle path is created by appending a.dSYMa to the executable name. --oso-prepend-path=dir Specifies a path to prepend to all debug symbol object file paths. -s, --symtab Dumps the symbol table found in executable or object file(s) and exits. -t n, --threads=n Specifies the maximum number (n) of simultaneous threads to use when linking multiple architectures. -v, --version Display the current version of llvm-dsymutil. --verbose Display verbose information when linking. -u, --update Update an existing dSYM file to contain the latest accelerator tables and other DWARF optimizations. This option will rebuild the a.apple_namesa and a.apple_typesa hashed accelerator tables. --minimize When used when creating a dSYM file, this option will suppress the emission of the a.debug_pubnamesa, and a.debug_pubtypesa sections since llvm-dsymutil has better equivalents: a.apple_namesa and a.apple_typesa. When used in conjunction with aupdate option, this option will cause redundant accelerator tables to be removed. --symbol-map=*bcsymbolmap* Either pass a .bcsymbolmap file or a directory containing the collection of .bcsymbolmap files for the different versions or architectures of your binary to unobfuscate the passed exe_file. Implies -u. --dump-debug-map Dump the executable debug-map (the list of the object files con- taining the debug information) in YAML format and exit. -y Treat exe_file as a YAML debug-map rather than an executable.
