SWDEV-165045 - Linux-Pro System Hard-Hang with Call Trace and VM Faults are observed while running ABAQUS-2018-OpenCL Sample on VEGA GPU
"-g" option caused shader compiler generated isa code which caused the VM fault. The root cause is still unknown. "-g" is not a feature for end user. So remove it.
Remove -g options from application. The affected API includes build, link and compile CL C kernel code.
Update ocltst compiler test to remove one test which uses "-g"
AMD_OCL_BUILD_OPTIONS_APPEND can be used to force "-g" option
Test:
Run the Abaqus as specfied in the JIRA twice. No VM fault.
In a simple OpenCL test application, driver can handle build option "-g -cl-mad-enable -g -D DDBUILD -D ok-g -g" correctly.
Teamcity test.
