llvm-addr2line-15 - Man Page

llvm-addr2line [options]

llvm-addr2line is an alias for the llvm-symbolizer(1) <https://llvm.org/docs/CommandGuide/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.
