> Key: HARMONY-4561
> URL: https://issues.apache.org/jira/browse/HARMONY-4561
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Mikhail Fursov
> Assignee: Mikhail Fursov
>
> For the test:
> public class TestExceptions {
> public static void main(String[] args) {
> //warmup VM first
> tryRaiseExceptions(1);
> long start = System.currentTimeMillis();
> tryRaiseExceptions(1000000);
> long res = System.currentTimeMillis() -start;
> System.out.println("completed in "+res+" msec");
> }
> public static void tryRaiseExceptions(int n) {
> for(int i=0; i<n; i++)
> try{
> throw new TException();
> }catch(TException throwable){
> TException ts = Test2.test(throwable);
> }
> }
> }
> public class Test2 {
> public static TException test(TException thr) {
> return thr;
> }
> }
> public class TException extends RuntimeException {
> }
> this region is marked as HOT after edge profile annotation but Test2.call is not inlined.
> }catch(TException throwable){
> TException ts = Test2.test(throwable);
> }
> Moreover, if I annotate Test2.test method with @inline pragma this call is also not inlined.
> This makes me think that our inliner ignores code that is reachable by exceptions only paths in its analysis.
