This is a C++ implementation of a Fuchsia log symbolizer. A symbolizer takes text logs as input, containing unsymbolicated stack traces indicated via a special Symbolizer markup format, and symbolizes them provided debug symbols.
E2E tests are disabled by default because they depend on the presence of //prebuilt/test_data/symbolizer/symbols, which is not downloaded by default. This could be done by jiri init -fetch-optional=symbolizer-test-data && jiri fetch-packages.
Once there are symbols, the E2E tests could be built by adding //tools/symbolizer:e2e_tests to args.gn and executed by fx test symbolizer_e2e_tests.
