When running gdb-caching-proc.exp, if skip_opencl_tests fails like this: ... (gdb) run Starting program: \ build/gdb/testsuite/outputs/gdb.base/gdb-caching-proc/opencltest13530.x CHK_ERR (clGetPlatformIDs (1, &platform, NULL), -1001) src/gdb/testsuite/lib/opencl_hostapp.c:73 error: Unknown [Inferior 1 (process 13600) exited with code 01] (gdb) skip_opencl_tests: OpenCL support not detected ... then this regexp in skip_opencl_tests fails to match: ... -re ".*$inferior_exited_re code.*${gdb_prompt} $" { ... so instead we hit the default clause after a 30 seconds timeout. With the iteration count set at 10, we end up taking 6 minutes to run this test-case.
This was fixed on master by commit d2b584a55b "[gdb/testsuite] Fix regexp in skip_opencl_tests".
