llvm-addr2line - a drop-in replacement for addr2line
====================================================
.. program:: llvm-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``.
- ``llvm-addr2line`` accepts an address with a '+' prefix, e.g. `+0x00777fff`.
This is treated as a symbol name by ``llvm-symbolizer``.
