Hi Alan,
It looks like you are running in a virtualized environment and somehow vbmi2 is enabled. However, the underlying hardware does not support vbmi2 feature as seen in /proc/cpuinfo from the log file. Therefore, when a vbmi2 instruction is executed, the hardware throws SIGILL.
I have reverified that the hotspot test case located at compiler/intrinsics/bigInteger/TestShift.java runs successfully on cpu-family 6, model 85, stepping 7 which is the same configuration as mentioned in the hs_error file from Remi. The intrinsic optimization is only for platforms that support vbmi2 feature.
Thanks,
Smita Kamath
