graal inlining decisions

Thomas --

I tried this command line
   mx --vm server unittest @-G:Log=InliningDecisions ArrayListGetTest

which only runs a single test, and I did not see any inlining decisions logged (one method is being compiled by the graal hsail compiler in the above case)

If I instead use a --vm graal command line
   mx --vm server unittest @-G:Log=InliningDecisions ArrayListGetTest

I see only the hosted x86 inlining decisions, not the hsail decisions.

We are compiling the HSAIL with with code like the following:

    public static HSAILCompilationResult getHSAILCompilationResult(StructuredGraph graph) {
        Debug.dump(graph, "Graph");
        TargetDescription target = new TargetDescription(new HSAIL(), true, 1, 0, true);
        HSAILBackend hsailBackend = new HSAILBackend(Graal.getRequiredCapability(GraalCodeCacheProvider.class), target);
        PhasePlan phasePlan = new PhasePlan();
        GraphBuilderPhase graphBuilderPhase = new GraphBuilderPhase(runtime, GraphBuilderConfiguration.getDefault(), OptimisticOptimizations.NONE);
        phasePlan.addPhase(PhasePosition.AFTER_PARSING, graphBuilderPhase);
        phasePlan.addPhase(PhasePosition.AFTER_PARSING, new HSAILPhase());
        new HSAILPhase().apply(graph);
        CallingConvention cc = getCallingConvention(runtime, Type.JavaCallee, graph.method(), false);
        CompilationResult compResult = GraalCompiler.compileGraph(graph, cc, graph.method(), runtime, 																	  replacements, // graalRuntime().getReplacements(),															  hsailBackend, target, null,
									  phasePlan, OptimisticOptimizations.NONE, new SpeculationLog());

If you run with "--vm server", the host should be the server compiler and therefore not be affected by the "-G:Log" value. Additionally, you can choose to either limit the number of unit tests executed or apply a "-G:MethodFilter=" argument to reduce the output to certain patterns of methods.
