>>> Hi all,
>>> could you please review this small fix? if JVM has been build w/o JVMCI, it won't have EnableJVMCI flag, as a result jtreg-ext/requires/VMProps will throw NPE trying to set 'vm.opt.final.EnableJVMC' property. w/ this fix, we will get 'null' value for nonexistent flags. compiler/graalunit/graalunit/generateTests.sh has been updated to generate tests which can handle such values, compiler/graalunit/ tests have been regenerated.
