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``.
