| This test produces two shared libraries: |
| |
| 1. libt-instr.so is instrumented |
| 2. libt-no-instr.so is built with profile rt linked in (via -u<hook>), but the object file is built |
| with instrumentation turned off. |
| |
| The test verifies concatenating profiles with only headers and no profile data and counters. |
