Actually what I meant in my original loop, that there is a dependency between every two consecutive iterations. So, how the loop vectorizer says 'we can vectorize this loop'? for(int k=20;k<50;k++) dataY[k] = dataY[k-1]; From: Henrique Santos [mailto:henrique.nazare.santos at gmail.com] Sent: Sunday, November 03, 2013 4:28 PM To: Sara Elshobaky Cc: <llvmdev at

Hello, I was trying to trace the Loop vectorizer of the LLVM, I wrote a simple loop with a clear dependency. But found that the debug shows that 'we can vectorize this loop' Here you are my loop with dependency: for(int k=20;k<50;k++) dataY[k] = dataY[k-1]; And the debug prints: LV: Checking a loop in "main" LV: Found a loop: for.body4 LV: Found an

Hi Sarah, the loop vectorizer runs not on the C code but on LLVM IR this c code was lowered to. Before the loop vectorizer runs many other optimization change the shape of this IR. You can see in the LLVM IR you referenced below, a preceding LLVM IR transformation has change your loop from: > for(int k=20;k<50;k++) > dataY[k] = dataY[k-1]; to > int a = d[19]; >

Notice that the code you provided, for globals and stack allocations, at least, is semantically equivalent to: int a = d[19]; for(int k = 20; k < 50; k++) dataY[k] = a; Like so, the load you see missing was redundant, probably hoisted by GVN/PRE and replaced with "%.pre".

So, what is the use of the profile passes in LLVM? Also, does llvm detect hot blocks of code for recompilation?

Hello, I'm using MCJIT to run some loops on my ARM processor. I was trying to perform some runtime optimizations on some function, and this requires recompiling the function at runtime. I know that this feature is not available yet in MCJIT , and to modify a function I have to create a new module with the newly optimized code. My questions are: - The newly created module can be

Hello, Please, I need more information on the runtime optimizer used in the LLVM JIT. - Where can I find it in the LLVM source code? - Are those runtime optimizations done on the LLVM representation code or on the machine code?

Hello, I'm executing my byte code program by the lli tool using mcjit. I need a way to find statistics about the number of instructions executed for my program. The -stats option does not include this value, are there any other way to know? I need this information to compare different versions of my bytecode program. Please advice Thanks in advance Sara Elsohbaky --------------

hello, I have a question about the llvm jit. Does it use the profile information generated during runtime to enhance the generated code for arm processor? according to 'LLVM: A Compilation Framework for Lifelong Program Analysis **<http://llvm.org/pubs/2004-01-30-CGO-LLVM.html>' it is available but can't find it in the current source code. I really appreciate any help. Thanks in

Hi, I was interested in telling the compiler not to inline a given function, and discovered that the __attribute__((noinline)) implements this using a global variable @llvm.noinline. It did not work for me initially. I noticed that @ llvm.noinline was being internalized by -internalize, dead-code-eliminated by -constmerge, causing this information not to reach the -inline pass. I am not sure if

Hi, I would like to know if there is any plan in the next future to support The GCC noinline attribute? Since LLVM does quiet a lot of inlining, these feature is interesting for us to do some function profiling. Thanks, Lionel. -------------- next part -------------- An HTML attachment was scrubbed...

The problem is that I am used to see/interpret diagrams in which all the autocorrelation Lags, except lag-1, are inside the

Dear All, I have to enter many lines of data in the same object. I usually use copy-paste to transfer data from an Word file to R. But, for large lines of data, R gets "confused" and gives an error message, i.e. it breaks one line somewhere, and lines get no meaning at all. Some times I solve that problem adding "enters" and making each line shorter, before I do
