* @summary converted from VM Testbase jit/tiered.
|
|
* VM Testbase keywords: [jit, quick]
|
|
* VM Testbase readme:
|
|
* Description
|
|
* The test verifies that JVM prints tiered events with -XX:+PrintTieredEvents
|
|
* for tiered compilation explicitly enabled with -XX:+TieredCompilation.
|
|
* If tiered compilation is explicitly disabled the test verifies that there are no
|
|
* output from PrintTieredEvents.
|
|
*
|
|
* @comment the test can't be run w/ jvmci compiler enabled as it enforces tiered compilation
|
|
* @requires vm.opt.UseJVMCICompiler != true
|
|
*
|
|
* @library /vmTestbase
|
|
* /test/lib
|

* @run driver vmTestbase.jit.tiered.Test
