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.
