thorin
thorin is an DWARF packaging utility for creating DWARF packages (*.dwp files) out of input
DWARF objects (*.dwo files; or *.o files with .dwo sections), supporting both the pre-standard
GNU extension format for DWARF packages and the standardized format introduced in DWARF 5.
thorin was written as part of the implementation of Split DWARF in rustc. A Rust implementation
of a DWARF packaging utility is easier to integrate into the compiler and can support features like
loading dwarf objects from archive files (or rustc's rlibs) which are helpful in supporting
cross-crate Split DWARF packaging in rustc.
Usage
thorin can read input DWARF objects from executables or can package arbitrary input dwarf
objects (including DWARF objects in archive files, such as Rust rlibs)! Install thorin using
cargo:
$ cargo install thorin-dwp-bin
$ thorin --help
thorin 0.2.0
merge dwarf objects into dwarf packages
USAGE:
thorin [OPTIONS] [--] [inputs]...
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-e, --exec <executables>... Specify path to executables to read list of dwarf objects from
-o, --output <output> Specify path to write the dwarf package to [default: -]
ARGS:
<inputs>... Specify path to input dwarf objects and packages
If the input objects are of DWARF version 5 or greater, then the output package will be in DWARF 5 format. For version 4 and below, the GNU Extension format will be used for the output package.
Stability
thorin's command-line interface is intended to be stable and have limited breaking changes.
