LLVM-ADDR2LINE(1)

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

SYNOPSIS

llvm-addr2line [options]

DESCRIPTION

llvm-addr2line is an alias for the llvm-symbolizer(1) <llvm-symbolizer.html> 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 <llvm-symbolizer.html#llvm-symbolizer-opt-f> to enable that.

•   llvm-addr2line defaults not to demangle function names. Use -C <llvm-symbolizer.html#llvm-symbolizer-opt-c> to switch the demangling on.

•   llvm-addr2line defaults not to print inlined frames. Use -i <llvm-symbolizer.html#llvm-symbolizer-opt-i> to show inlined frames for a source code location in an inlined function.

•   llvm-addr2line uses --output-style=GNU <llvm-symbolizer.html#llvm-symbolizer-opt-output-style> by default.

•   llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS.

•   llvm-addr2line accepts an address with a '+' prefix, e.g. +0x00777fff. This is treated as a symbol name by llvm-symbolizer.
