NAME

       llvm-addr2line - a drop-in replacement for addr2line

SYNOPSIS

       llvm-addr2line [options]

DESCRIPTION

       llvm-addr2line  is  an  alias  for  the  llvm-symbolizer(1)  <llvm-symbolizer.html>  tool  with different
       defaults. The goal is to make it a drop-in replacement for GNU’s addr2line.

       Here are some of those differences:

       • llvm-addr2line interprets all addresses as hexadecimal and  ignores  an  optional  0x  prefix,  whereas
         llvm-symbolizer  attempts  to  determine  the base from the literal’s prefix and defaults to decimal if
         there is no prefix.

       • llvm-addr2line   defaults   not   to   print   function   names.    Use    -f    <llvm-symbolizer.html#
         llvm-symbolizer-opt-f> to enable that.

       • llvm-addr2line   defaults   not   to   demangle   function   names.   Use   -C   <llvm-symbolizer.html#
         llvm-symbolizer-opt-c> to switch the demangling on.

       • llvm-addr2line   defaults   not   to   print   inlined   frames.    Use    -i    <llvm-symbolizer.html#
         llvm-symbolizer-opt-i> to show inlined frames for a source code location in an inlined function.

       • llvm-addr2line   uses   –output-style=GNU   <llvm-symbolizer.html#llvm-symbolizer-opt-output-style>  by
         default.

       • llvm-addr2line parses options  from  the  environment  variable  LLVM_ADDR2LINE_OPTS  instead  of  from
         LLVM_SYMBOLIZER_OPTS.

       • llvm-addr2line  accepts  an  address  with a ‘+’ prefix, e.g. +0x00777fff.  This is treated as a symbol
         name by llvm-symbolizer.
