Source code, Makefile and README
Clang generates incorrect instructions omitting multiversioned function call.
STEPS TO REPRODUCE:
1. Download the attachment and run 'make' in bug_report directory
2. Execute test and observe that nothing is printed
3. Comment out line 4 in PrintTester.C
4. Build again with 'make' and run test
SAMPLE RESULTS:
(running on a machine with avx512f support)
~/bug_report> make
...
~/bug_report> ./test
(after step3)
~/bug_report> make
...
~/bug_report> ./test
TARGET AVX512F!</pre>
