// Integration test for the R8 retracing tool.

// The retracing tool is a developer tool and part of the build tools.
// The following tests are structured so that the app and retrace tool
// are invoked exactly as a normal build would. The check that they
// produce the correct result is then postponed to a test so that a
// retrace tool failure will not result in a build failure.

// Rule to dexdump the content of a sample app.
// The dexdump is used to simulate a raw stack trace from the app.
