Details

Instead of running tests one by one, we could run them in parallel and with different GCOV_PREFIX get the gcdas which correspond to each test.
I think :marco made a good point at the last meeting about how these will only run in large batches periodically, and not very often, so we don't need to worry about the performance in per-test-coverage as much as regular builds. But if we speed up regular builds (like with the ramdisk change for example), per-test-coverage mode will benefit from them.
Summary: Use differents GCOV_PREFIX for parallel tests for per-test coverage → Use different GCOV_PREFIX for parallel tests for per-test coverage
Severity: normal → S3
