$ xref src

Rust source locations (panic Locations) the function containing an address passes.

Extracts core::panic::Location structs from .rodata even after strip --strip-all, linking stripped functions back to exact file:line:col anchors.

Usage

xref src <ADDR>

Reading the output

• The first line is the function range; each following line is an instruction that passes a panic Location and the file:line:column it names. The last line counts them.

Limits

• Only locations passed to panic paths are known; they point to where a bounds check or unwrap was written, which can be inlined code from another file.

Provenance

Recorded with a development build of xref after 0.4.0 on Linux x86-64, on xref.stripped = a stripped xref build (the binary of the home-page examples). Output is unchanged except that whitespace at the end of each line and empty lines at the end of the output are removed; long outputs are cut where marked.
