llvm-addr2line - a drop-in replacement for addr2line

SYNOPSIS

:program:`llvm-addr2line` [options]

DESCRIPTION

:program:`llvm-addr2line` is an alias for the :manpage:`llvm-symbolizer(1)` tool with different defaults. The goal is to make it a drop-in replacement for GNU's :program:`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 to enable that.
  • llvm-addr2line defaults not to demangle function names. Use -C to switch the demangling on.
  • llvm-addr2line defaults not to print inlined frames. Use -i to show inlined frames for a source code location in an inlined function.
  • llvm-addr2line uses --output-style=GNU by default.
  • llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS.
