NAME¶
llvm-symbolizer - convert addresses into source code locations
SYNOPSIS¶
llvm-symbolizer [options]
DESCRIPTION¶
llvm-symbolizer reads object file names and addresses from standard input and prints corresponding source code locations to standard output. If object file is specified in command line, llvm-symbolizer reads only addresses from standard input. This program uses debug info sections and symbol table in the object files.
EXAMPLE¶
$ cat addr.txt a.out 0x4004f4 /tmp/b.out 0x400528 /tmp/c.so 0x710 /tmp/mach_universal_binary:i386 0x1f84 /tmp/mach_universal_binary:x86_64 0x100000f24 $ llvm-symbolizer < addr.txt main /tmp/a.cc:4 f(int, int) /tmp/b.cc:11 h_inlined_into_g /tmp/header.h:2 g_inlined_into_f /tmp/header.h:7 f_inlined_into_main /tmp/source.cc:3 main /tmp/source.cc:8 _main /tmp/source_i386.cc:8 _main /tmp/source_x86_64.cc:8 $ cat addr2.txt 0x4004f4 0x401000 $ llvm-symbolizer -obj=a.out < addr2.txt main /tmp/a.cc:4 foo(int) /tmp/a.cc:12
OPTIONS¶
- -obj
- Path to object file to be symbolized.
- -functions=[none|short|linkage]
- Specify the way function names are printed (omit function name, print short function name, or print full linkage name, respectively). Defaults to linkage.
- -use-symbol-table
- Prefer function names stored in symbol table to function names in debug info sections. Defaults to true.
- -demangle
- Print demangled function names. Defaults to true.
- -inlining
- If a source code location is in an inlined function, prints all the inlnied frames. Defaults to true.
- -default-arch
- If a binary contains object files for multiple architectures (e.g. it is a Mach-O universal binary), symbolize the object file for a given architecture. You can also specify architecture by writing binary_name:arch_name in the input (see example above). If architecture is not specified in either way, address will not be symbolized. Defaults to empty string.
- -dsym-hint=<path/to/file.dSYM>
- (Darwin-only flag). If the debug info for a binary isn't present in the default location, look for the debug info at the .dSYM path provided via the -dsym-hint flag. This flag can be used multiple times.
EXIT STATUS¶
llvm-symbolizer returns 0. Other exit codes imply internal program error.
