## This test makes sure we can extract the instrumentation map from an
## XRay-instrumented PIE file.
## Generated from the following source:
## __attribute__((xray_always_instrument)) void foo() {}
## __attribute__((xray_always_instrument)) void bar() {}
## __attribute__((xray_always_instrument)) void jar() {}
## Built with the following arguments:
## -target armv7a-linux-androideabi -nostdlib -fxray-instrument -fPIC -shared
