Summary: This matches the behavior of GNU addr2line. We previously treated hexadecimal addresses as binary if they started with 0b, otherwise as octal if they started with 0, otherwise as decimal. This only affects llvm-addr2line; the behavior of llvm-symbolize is unaffected.

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``.
