Quoted from gbenson:
"
LLVM generates all code into a buffer of fixed size, and once this buffer is
filled it simply exits with an abort(), taking out the VM. Clearly this needs
fixing for Shark.
There are two possible places a fix could occur:
1) In lib/ExecutionEngine/JIT/JITEmitter.cpp, in JITEmitter::finishFunction.
This is where the abort() is; there's a FIXME saying to allocate more space
and try again.
2) In lib/ExecutionEngine/JIT/JITMemoryManager.cpp, by extending the default
memory manager to be able to grow the block or something.
