[LLVMdev] vmjc + llc questions

[Tim Hartley]

Hi,

I've been trying to compile a simple helloworld Java program to native
code, and I've been having trouble. I'm tripping an assertion that I don't
quite understand yet. I'm just curious if anybody can point me in the right
direction.

$ javac helloworld.java
$ vmjc -o helloworld.bc helloworld.class
$ llc -load=<...>/Release+Asserts/lib/StaticGCPrinter.so helloworld.bc -o
helloworld.s
llc: VmkitGCPrinter.cpp:268: llvm::Constant* FindMetadata(const
llvm::Function&): Assertion `0 && "Should have found a JavaMethod"' failed.

Stack dump:
0. Program arguments: llc
-load=<...>/Release+Asserts/lib/StaticGCPrinter.so helloworld.bc -o
helloworld.s
1. Running pass 'Function Pass Manager' on module 'helloworld.bc'.

Thanks,
Tim
