llvm-symbolizer is used by sanitizers to symbolize errors discovered by sanitizer, but there's no way to pass options to llvm-symbolizer since the tool is invoked directly by the sanitizer runtime. Therefore, we don't have a way to pass options needed to find debug symbols such as -dsym-hint or -debug-file-directory. This change enables reading options from the LLVM_SYMBOLIZER_OPTS in addition to command line which can be used to pass those additional options to llvm-symbolizer invocations made by sanitizer runtime.

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:
|
|
|
|
- Defaults not to print function names. Use `-f`_ to enable that.
|
|
|
|
- Defaults not to demangle function names. Use `-C`_ to switch the
|
|
demangling on.
|
|
|
|
- Defaults not to print inlined frames. Use `-i`_ to show inlined
|
|
frames for a source code location in an inlined function.
|
|
|
|
- Uses `--output-style=GNU`_ by default.
|
|
|
|
- Parses options from the environment variable ``LLVM_ADDR2LINE_OPTS``.
