{program}llvm-addr2line [options]
{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.llvm-addr2line accepts an address with a ‘+’ prefix, e.g. +0x00777fff. This is treated as a symbol name by llvm-symbolizer.{manpage}llvm-symbolizer(1)
