| ## 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 |
