Pavel Afremov updated HARMONY-5084:
-----------------------------------

    Attachment: lightJNI.patch

Build on Linux x86-32 was fixed in attached patch.

But sometimes VM assert on the following stack:

  0: ?? (??:-1)
  1: abort (??:-1)
  2: __assert_fail (??:-1)
  3: vm_get_ip_from_regs(VM_thread*) (thread_manager.cpp:201)
  4: general_signal_handler (signals_common.cpp:540)
addr2line: '[vdso]': No such file
  5: ?? (??:-1)
<end of stack trace>

>          Issue Type: New Feature
>          Components: DRLVM
>         Environment: Tested on Win32 IA32 platform. I think on IA32 Linux it will be also o.k.

> This patch adds new pass called "light_jni". This pass eliminates stub calling for some methods which do not need stubbing (they do not use JNIEnv for example). This patch contain some hardcoded names of such methods (all java/lang/Math methods and java/lang/VMThreadManager::currentThread). You can add functions in list using command line param:
> -XX:jit.arg.codegen.light_jni.light_jni_methods=ClassName::MethodName,ClassName::MethodName,...
> Patch was tested on some microbenchmarks and  Dacapo::jython (with n=4). The results for Dacapo::jython look good:
> mode     on     off
> server   6700   7800     
> client    7200   8000
