Everytime you call recompileAndRelinkFunction. It calls runJITOnFunction without specifying the MCI argument, which get defaulted to NULL. Gianluca -- It was a

Please add a test to http://llvm.org/viewvc/llvm-project/llvm/trunk/unittests/ExecutionEngine/JIT/JITTest.cpp?view=markup verifying that recompileAndRelinkFunction() keeps working. Then this fix will look fine to me. On Tue, Dec 22, 2009 at 12:23 AM, Gianluca Guida <glguida at gmail.com> wrote: > On Tue, Dec 22, 2009 at 6:14 AM, Chris Lattner <clattner at apple.com> wrote: >>

Dear all, I have a question on the runJITOnFunction() function in JIT.cpp. The second argument MCI must be used to create a MCIListener in the runJITOnFunction() function. However, the JIT::recompileAndRelinkFunction() just calls the runJITOnFunction() like this: " runJITOnFunction(F);", leaving the second argument, the MCI, empty. As a result, if the call the

Dear All: I am pretty new to xen-devel, please correct me in the following. Assume we have the following terms GPT: guest page table SPT: shadow page table (Question a) When guest OS is running, is it always using SPT for address translation? If it is the case, how does guest OS refer and modify its own GPT content? It seems that there is a page table entry in SPT for the GPT page. (Question

Hi Bill, I'm coincidently planning right now on doing exactly the same things as you. I haven't yet had a chance to implement the code, but I can point you to how I currently believe you can get access to what you need. If you take a look at the code for the implementation of lvm::JIT::runJITOnFunction(Function *, MachineCodeInfo *), you'll see that if a MachineCodeInfo parameter is

Hi, I am trying to recompile a function during runtime, using JIT compilation (not MCJIT). I choose JIT over MCJIT, because I only want to modify a single function and not the whole module. I am successfully able to recompile the function, but after that, the original function definition is lost. And if I try to recompile, it recompiles with the new function definition. I figured out two

Dear All, "recompileAndRelinkFunction" found in Interpreter and previously in JIT, is not found in MCJIT. Can I just implement it in MCJIT like its old definition in JIT, or it contradicts with some design issue in MCJIT?

Thanks for all the hints everyone. Based on your suggestion, O.J., I've added code to toy.cpp from the tutorial to disassemble. ready> 1+1; ready> movabsq $140737353367568, %rax movsd (%rax), %xmm0 ret Evaluated to 2.000000 ready> Which looks correct by inspection - printing the byte array to stdout and feeding it to llvm-mc offline produces the same code as one would also

Hi, I am starting to poke at the LLVM JIT, which seems to be in need of some TLC. If you are a "sophisticated" JIT user and are using either internal APIs (either by integrating with LLVM, or by other C++ tricks), or are using obscure or poorly documented public APIs (e.g., why is runJITOnFunction exposed?) please make me aware of it! I reserve the right to break anything which

Will this poking include converting the JIT to use the MC framework? I've added an MC based asm parser, disassembler, and code emitter recently to the MBlaze backend and it would be nice to get JIT support automatically :) -- Wesley Peck On Nov 12, 2010, at 7:42 PM, Daniel Dunbar wrote: > Hi, > > I am starting to poke at the LLVM JIT, which seems to be in need of some TLC. >

Hi I hope this is a proper place to put my question. I've compiled Kaleidoscope from "Adding JIT and Optimizer Support" tutorial. Basically it works just fine but when I try to run extern'ed putchard function it aborts. Please, tell me what am I doing wrong? Here is more information: My PC runs FreeBSD. I've copied the toy source code exactly and didn't change it.

Hello, In processors supporting VPID I think we should invalidate the VPID mapping in the TLB after a shadow invlpg (in case EPT is turned off).

Hello, The fast emulation path patch introduced a bug when we have an event injection during a write to a pagetable: after removing shadows we still jump to the done label, releasing the lock even if we aren''t grabbing it.

Hi I am very new to R and statistical programming in general. I am trying to reorder data from a .csv file. I have managed to import the data and create a zero matrix. I am now trying to fill the matrix. There seems to be some problem with this section of my code. I have highlighted the dodgy code in red.

Hello All, Anyone out there using ISDN PRI from either MCI or XO/Allegiance? Gotta make the choice today and the difference per month is only about $25 in favor of MCI. Billing is pretty much the same between the two so I have pretty much no point of reference on which to choose. Any thoughts from anyone experienced with these two compnies would be greatly appreciated! Thanks, Wiley
