   - To only run the failed tests use -DTest, -DExclude,
     and/or -DScenarios.
   - To also get the standard output of the test VM run with
     -DReportStdout=true or for even more fine-grained logging
     use -DVerbose=true.

Note, -XX:+UseKNLSetting flag reduce number of available avx512 instructions to amulate old Intel's CPU. So it is reasonable that some vector instructions can't be generated with it. But my impression was that IR framework fork process to avoid such issues when conflicting flags are specified by testing.

ILW = Test failure due to methods that cannot be compiled, single IR test and problem-listed already, no workaround = MLH = P4

I also noticed this in the logs: IR verification disabled due to using non-whitelisted JTreg VM or Javaoptions flag(s). There are two issues: 1) The IR verification appears disabled for all the newly added rehape tests because the hotspot_vector_1 group is run under various flags in Oracle's test infrastructure. 2) The addition of -XX:+UseKNLSetting seems to be affecting a subset of the AVX512 cast tests. It's not clear if such cast tests need to be split accordingly or need not be run with this flag.
