Hi,
I'm new to VMKit and I'm trying to use its AOT Java compiler but I'm
immediately getting an error message which I don't understand.
Everything was compiler as suggested in the Getting Started tutorial, using
GNU Classpath. I try to run:
llcj ../../tools/trainer/Release+Asserts/HelloWorld.class
and get the following output:
Can not materiale a function in AOT mode.0 vmjc

21 libc.so.6 0x00007f4fbb192d1d clone + 109
This is produced inside the JavaAOTCompiler.h, in
method materializeFunction which is called from JavaMethod::compiledPtr.
What am I doing wrong?
Cheers,
David

Hi David, I don't know where is the problem, but I'm investigating that :) Basically, I never had to use llcj and I don't know how and if it works... I send you a mail as soon as I understand how llcj should work.

Hi Gaël Thanks for looking into this. I've made a little progress myself. "llcj" must be run from the root directory of the compiled Java class files, i.e. the "tools/trainer/Release+Asserts" directory. Then its call to "vmjc" succeeds, it calls "opt", but then it fails again when it tries to run "llc", saying that it cannot find the vmkit garbage collector. So I added the "static-gc-printer.so" with a "-load" option. Now it finds the GC, but that still fails with: llc: VmkitGCPrinter.cpp:270: llvm::Constant *FindMetadata(const llvm::Function &): Assertion `0 && "Should have found a JavaMethod"' failed. 0 llc 0x0000000000ff1295 llvm::sys::PrintStackTrace(_IO_FILE*) + 37 1 llc 0x0000000000ff1753 2 libpthread.so.0 0x00007fce83f1b880 3 libc.so.6 0x00007fce8317a389 gsignal + 57 4 libc.so.6 0x00007fce8317b788 abort + 328 5 libc.so.6 0x00007fce831734a6 6 libc.so.6 0x00007fce83173552 7 static-gc-printer.so 0x00007fce82f41a7e 8 static-gc-printer.so 0x00007fce82f41fe2 9 llc 0x0000000000b58781 llvm::AsmPrinter::doFinalization(llvm::Module&) + 1217 10 llc 0x0000000000f8fa1e llvm::FPPassManager::doFinalization(llvm::Module&) + 94 11 llc 0x0000000000f8fd2e llvm::MPPassManager::runOnModule(llvm::Module&) + 686 12 llc 0x0000000000f904df llvm::PassManagerImpl::run(llvm::Module&) + 543 13 llc 0x0000000000524f2a main + 6506 14 libc.so.6 0x00007fce83166b05 __libc_start_main + 245 15 llc 0x00000000005234f3 Stack dump: 0.
