# llvm-addr2line - a drop-in replacement for addr2line

## SYNOPSIS

llvm-addr2line [options]

## DESCRIPTION

llvm-addr2line is an alias for the llvm-symbolizer(1) tool with different defaults. The goal is to make it a drop-in replacement for GNU’s 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`.
