| 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``. |
