DuckDB Dwarf Extension

A duckdb extension for reading DWARF information. I'm still trying to think of interseting use cases.

Building

Managing dependencies

./install-libdwarf.sh
make reldebug

Build steps

Now to build the extension, run:

make release

The main binaries that will be built are:

./build/release/duckdb
./build/release/test/unittest
./build/release/extension/<extension_name>/<extension_name>.duckdb_extension

Running the extension

--- On Mac you might need to run dsymutil on ./build/reldebug/duckdb for this to work.
D from dwarf_info('./build/reldebug/duckdb')

A more interesting query:

create table die_attrs as
  select * exclude(dwarf_attributes), unnest(dwarf_attributes,recursive:=true)
  from dwarf_info('./build/reldebug/duckdb');

pivot (
  select dwarf_tag, dwarf_offset, dwarf_attr_key, dwarf_attr_value
  from die_attrs
  where dwarf_tag = 'DW_TAG_class_type'
) on dwarf_attr_key using first(dwarf_attr_value);
