Hi, Sorry for bothering you guys again. I got problem when I am trying to recover the Global Variable Initial value. What I did is like the following ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); // the above instruction enable me to get the content of initial string of global variable, like char a[10] ="test global"; And then I make some change for

Hi, I got a problem when I am trying to insert a call function with pointer arguments. The function C proto-type is the following, void stat_func(char *); >ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); ...... >Function *exFunc = M->getOrInsertFunction("stat_func", Type::VoidTy, PointerType::get(Type::SByteTy),0); >std::vector<Value*>

Hi, We noticed a dramatic slowness when writing to a gluster disk when compared to writing to an NFS disk. Specifically when using dd (data duplicator) to write a 4.3 GB file of zeros: * on NFS disk (/home): 9.5 Gb/s * on gluster disk (/gdata): 508 Mb/s The gluser disk is 2 bricks joined together, no replication or anything else. The hardware is (literally) the same: * one server with

Howdy, I am having a problem with a library compiled from some legacy fortran code. I can call the library, it runs as it should, returns a list, and gives a ">" prompt, but then locks up the R session. Functions typed in return nothing. ctrl-c results in a new prompt that is still locked up, and R overwhelms the processor. This happens on Mac, Windows, and Linux exactly the same. I

Hello, I have a problem of generating a load instruction. The LLVM bytecode is: ------------------------ entry: ... %2 = call i32 (...)* @atoi(i8*%1) nounwind /*<- Insertpos*/ ... -- bb1: .. %5 = icmp sgt i32 %2, %i.0 ... ----------------- Now I have pb: pointer to the Value object of *%2* of bb1. Here, I want to generate a load instruction and I did it as: new LoadInst(pb,

Andy, I've described that issue (see below) when you were out of town... I think I am getting more context on it. Please take a look... So, in short, when the new MI scheduler performs move of an instruction, it does something like this: // Move the instruction to its new location in the instruction stream. MachineInstr *MI = SU->getInstr(); if (IsTopNode) {

Hi , I am using LLVM for my Post Graduate course project on Optimization. I am trying to do some insrtumentation to the bytecode.I 've been going through your Instrumentation code for the past few days in /llvm/lib/Transforms/Instrumentation folder and finally found two ways of instrumentation : 1) injecting LLVM bytecode instructions 2) calling an external C function. I am trying both and

I have been pondering what the right representation should be and what kind of impact it might have on the LLVM code generator.

Andy, Lang, Thanks for the suggestion. I have spent more time with it today, and I do see some strange things in liveness update. I am not at the actual cause yet, but here is what I got so far: I have the following live ranges when I start scheduling a region: R2 = [0B,48r:0)[352r,416r:5)... R3 = [0B,48r:0)[368r,416r:5)... R4 = [0B,32r:0)[384r,416r:4)... R5 = [0B,32r:0)[400r,416r:4)...

Hi, I want to access an array in my instrumentation code. For example: GlobalVariable: int *counter; //counter the number of load/store operations in run-time int *counterArray; //record the load/store addresses //increase the counter if a load/store is performed std::vector<Constant *>index(2); index[0] = Constant::getNullvalue(Type:getInt32Ty(Context)); index[1] =

Hi Sergei, Andy, Sorry - I got distracted with some other work. I'm looking into this and PR13719 now. I'll let you know what I find out. Sergei - thanks very much for the investigation. That should help me pin this down. Cheers, Lang. On Tue, Aug 28, 2012 at 2:33 PM, Sergei Larin <slarin at codeaurora.org> wrote: > Andy, Lang, > > Thanks for the suggestion. >

Hi Lang, Just one more quick question. in LiveIntervalAnalysis.cpp In SlotIndex findLastUseBefore(unsigned Reg, SlotIndex OldIdx) Did you really mean to use for (MachineRegisterInfo::use_nodbg_iterator UI = MRI.use_nodbg_begin(Reg), UE = MRI.use_nodbg_end(); UI != UE; UI.skipInstruction()) {} Aren't we currently dealing with units,

Also, you have written them in some kind of C-style idiom. What are the declarations

Volodya, I think you may need to update your CFE and rebuild. I compiled the test using my local build and I didn't get the results you see below. I'm also very surprised to see this output. The first %tmp.11 should have been %tmp.1 .. not sure how it got corrupted. In any event, the attachment is obviously generated by code that runs quite differently because the virtual register names

FYI, I am building on alpine 3.10 and 3.11 I am getting this build[1] error. I think these header files of dovecot are not correct. Or are they?

Hi, Thank Brian Gaeke so much. Following TraceBasicBlocks.cpp, I modified the code as below and could insert instruction or function I need into anywhere in Module. But it works well without BB->getInstList().push_back(InstrCall), and if I add the BB->getInstList().push_back() following new CallInst(), I got error information when runing opt. What is the reason for it? And is it necessary
