Hi, I've just installed llvm from trunk and lli seems to have lost the -fast option. Can we have it back please? Mark.

Hi, I'm slightly confused here. Not only, has -fast flag disappeared from lli, the ExecutionEngine:createJIT API has changed as well. I suspect these are related :) What will this do to the speed of JIT code generation? What effect do the new optimisation levels in ExecutionEngine:createJIT have? What lli flag (if any) corresponds to these optimisation levels? And is this documented anywhere? Mark.

According to the comments for the commit, this was done to fix the large code model on amd64, but this affects JITs which can guarantee that both the caller and callee have 32 bit addresses, since the code model is set uncoditionally to Large, even if another code model was passed to createJIT (): http://llvm.org/viewvc/llvm-project/llvm/trunk/lib/Target/X86/X86TargetMachine.cpp?r1=86251&r2=88984&pathrev=88984 Would it be possible to fix this or make it configurable ? thanks Zoltan -------------- next part ---...

...arth said: aph, you need to intercept the "endFunctionBody" call on the memory manager, it will tell you the start pointer and the end pointer But how can I do this? The obvious way would be for me to inherit from DefaultMemoryManager and pass an instance of my class to ExecutionEngine::createJIT. But DefaultMemoryManager isn't public so I can't inherit from it. It's not at all obvious to me how I'm supposed to intercept endFunctionBody. Thanks, Andrew.

The CodeModel is definitely intended to be configurable, specifically so that users can specify the guarantees their JITMemoryManager provides. Still, it's supposed to be an opt...

I don't know the MC-JIT you mentioned can be used as a JIT. Currently, a JIT is created by ExecutionEngine::createJIT. Can you give more information about the MC-JIT?

I can get into the JIT::createJIT function, but i then fail to find an appropriate JIT for my architecture (which is actually X86_64-win64, via visual c++ compilation.

I see two problems in your code 1) you need to #include "llvm/ExecutionEngine/JIT.h" 2) you must pass an empty string to EngineBuilder::setErrorStr. See JIT::createJIT for the reason.

Hi everyone ! If I call ExecutionEngine::createJIT (or EngineBuilder::create) more than one time, the second time fails on a assertion "Multiple JIT resolvers?". It seems that the JIT is designed to be a singleton in the process, and I was wondering if it was something mandatory. How hard will it be to make it a non-singleton object ? Is...

Hello, I am using Ubuntu 11.10 64-bit. Following the instructions on the VMKit website I grabbed llvm, clang, and vmkit via svn (and GNU Classpath via the link of the page). Compilation of llvm, clang and classpath went fine. I had problems compiling vmkit, which seem to be related to a TargetOptions being required as a parameter when creating a TargetMachine in LLVM. This led to a couple other
