.TH "LLVM-ADDR2LINE" "1" "2026-07-15" "22" "LLVM"
.SH NAME
llvm-addr2line \- a drop-in replacement for addr2line
.SH SYNOPSIS
.sp
\fBllvm\-addr2line\fP [\fIoptions\fP]
.SH DESCRIPTION
.sp
\fBllvm\-addr2line\fP is an alias for the \fBllvm\-symbolizer(1) \%<llvm-symbolizer\:.html>\fP
tool with different defaults. The goal is to make it a drop\-in replacement for
GNU\(aqs \fBaddr2line\fP\&.
.sp
Here are some of those differences:
.INDENT 0.0
.IP \(bu 2
\fBllvm\-addr2line\fP interprets all addresses as hexadecimal and ignores an
optional \fB0x\fP prefix, whereas \fBllvm\-symbolizer\fP attempts to determine
the base from the literal\(aqs prefix and defaults to decimal if there is no
prefix.
.IP \(bu 2
\fBllvm\-addr2line\fP defaults not to print function names. Use \-f \%<llvm-symbolizer\:.html#\:llvm-symbolizer-opt-f> to enable
that.
.IP \(bu 2
\fBllvm\-addr2line\fP defaults not to demangle function names. Use \-C \%<llvm-symbolizer\:.html#\:llvm-symbolizer-opt-c> to
switch the demangling on.
.IP \(bu 2
\fBllvm\-addr2line\fP 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.
.IP \(bu 2
\fBllvm\-addr2line\fP uses \-\-output\-style=GNU \%<llvm-symbolizer\:.html#\:llvm-symbolizer-opt-output-style> by default.
.IP \(bu 2
\fBllvm\-addr2line\fP parses options from the environment variable
\fBLLVM_ADDR2LINE_OPTS\fP instead of from \fBLLVM_SYMBOLIZER_OPTS\fP\&.
.IP \(bu 2
\fBllvm\-addr2line\fP accepts an address with a \(aq+\(aq prefix, e.g. \fI+0x00777fff\fP\&.
This is treated as a symbol name by \fBllvm\-symbolizer\fP\&.
