1462 libgomp ``versions'' its symbols (OMP_1.0, OMP_2.0, OMP_3.0, ...) while also
1463 retaining the default version which libomp uses: VERSION (defined in
1464 exports_so.txt). If you want to see the versioned symbols for libgomp.so.1
1465 then just type:
1466
1467 objdump -T /path/to/libgomp.so.1 | grep omp_
1468
1469 Example:
1470 Step 1) Create __kmp_api_omp_set_num_threads_10_alias which is alias of
1471 __kmp_api_omp_set_num_threads
1472 Step 2) Set __kmp_api_omp_set_num_threads_10_alias to version:
1473 omp_set_num_threads@OMP_1.0
1474 Step 2B) Set __kmp_api_omp_set_num_threads to default version:
1475 omp_set_num_threads@@VERSION
