1 llvm-symbolizer - convert addresses into source code locations 2 ============================================================== 3 4 SYNOPSIS 5 -------- 6 7 :program:`llvm-symbolizer` [options] 8 9 DESCRIPTION 10 ----------- 11 12 :program:`llvm-symbolizer` reads object file names and addresses from standard 13 input and prints corresponding source code locations to standard output. This 14 program uses debug info sections and symbol table in the object files. 15 16 EXAMPLE 17 -------- 18 19 .. code-block:: console 20 21 $ cat addr.txt 22 a.out 0x4004f4 23 /tmp/b.out 0x400528 24 /tmp/c.so 0x710 25 /tmp/mach_universal_binary:i386 0x1f84 26 /tmp/mach_universal_binary:x86_64 0x100000f24 27 $ llvm-symbolizer < addr.txt 28 main 29 /tmp/a.cc:4 30 31 f(int, int) 32 /tmp/b.cc:11 33 34 h_inlined_into_g 35 /tmp/header.h:2 36 g_inlined_into_f 37 /tmp/header.h:7 38 f_inlined_into_main 39 /tmp/source.cc:3 40 main 41 /tmp/source.cc:8 42 43 _main 44 /tmp/source_i386.cc:8 45 46 _main 47 /tmp/source_x86_64.cc:8 48 49 OPTIONS 50 ------- 51 52 .. option:: -functions 53 54 Print function names as well as source file/line locations. Defaults to true. 55 56 .. option:: -use-symbol-table 57 58 Prefer function names stored in symbol table to function names 59 in debug info sections. Defaults to true. 60 61 .. option:: -demangle 62 63 Print demangled function names. Defaults to true. 64 65 .. option:: -inlining 66 67 If a source code location is in an inlined function, prints all the 68 inlnied frames. Defaults to true. 69 70 .. option:: -default-arch 71 72 If a binary contains object files for multiple architectures (e.g. it is a 73 Mach-O universal binary), symbolize the object file for a given architecture. 74 You can also specify architecture by writing ``binary_name:arch_name`` in the 75 input (see example above). If architecture is not specified in either way, 76 address will not be symbolized. Defaults to empty string. 77 78 EXIT STATUS 79 ----------- 80 81 :program:`llvm-symbolizer` returns 0. Other exit codes imply internal program error. 82
