Subject: Successfull building of JDK8u
Message-ID: <CAFtewT2+ww-_FHJm7DF=W54edwFc-iBixXKcUFQS=rrWAjiQNw@mail.gmail.com>

Dear all,
Finally I have Succeeded to build jdk8u,I made these changes aggressively
so I'm worry about unexpected runtime behaviors although I've test some
hello world programs an the results were correct.I decided to share the
changes that I've done with you
Could you review  my changes tell me if some changes that I've done might
have unexpected errors in the future ?
In ciTypeFlow.cpp I've added two macros (#ifdef Compiler2) :lines 38,41
2652,2662
In sharkCompiler.cpp I've changed   Arena arena(mtCompiler); line 170 to
Arena arena(mtCompiler); line 171
In sharkCompiler.cpp I've commented lines 318 until 323 //tty->print
In sharkRuntime.cpp I've commented lines 191 until 196 //again tty->print
Finaly I've test compile and test some programs with binaries which are
located in linux-x86_64-normal-zeroshark-release/images/j2sdk-image and
everything was fine ,
As I said I before I want to hack Shark JIT in order to just convert Java 8
bytecode to LLVM IR,Do you have any suggestion for me which could help me
out,Does anybody know which class or method are more responsible for
generating LLVM IR ?
Right now I  just want to debug the whole Shark JIT codebase by dumping the
variables and objects .Does anybody know a better solution ?

Thanks

Subject: Problem with Lamdas
Message-ID: <CAFtewT2jneGk6syiQ7ukNxVrPouySNi6X83gpMFB=wv0yrffbQ@mail.gmail.com>

Hello guys,
Finally I've succeeded  to generate LLVM IR from Shark JIT.
My problem is with Java 8 Lambdas,When I want to run a lamda or generate
LLVM IR from lambdas ,I get this Error :
Exception in thread "main" java.lang.InternalError:
BMH.reinvoke=Lambda(a0:L/SpeciesData<L>,a1:L)=>{
    t2:L=MethodHandleImpl.array();
    t3:L=Species_L.argL0(a0:L);

Does anyone here have solution for these weird Errors ?
