# llvm-addr2line - a drop-in replacement for addr2line
## SYNOPSIS
**llvm-addr2line** [*options*]
## DESCRIPTION
**llvm-addr2line** is an alias for the [llvm-symbolizer](llvm-symbolizer) tool
with different defaults. The goal is to make it a drop-in replacement for
GNU's **addr2line**.
Here are some of those differences:
* Defaults not to print function names. Use [-f](llvm-symbolizer-opt-f)
to enable that.
* Defaults not to demangle function names. Use [-C](llvm-symbolizer-opt-C)
to switch the demangling on.
* Defaults not to print inlined frames. Use [-i](llvm-symbolizer-opt-i)
to show inlined frames for a source code location in an inlined function.
* Uses [--output-style=GNU](llvm-symbolizer-opt-output-style) by default.
