Hi, I am using LLVM for implementing LoopFission pass. I am using LoopPass. I know that for checking circular dependency in loop I have to use LoopDependenceAnalysis This is what i want to do. for(int i = 0; i< n ; i++){ s1 : a[i] = a[i] + x[i]; s2 : x[i] = x[i+1] + i*2 ; } /**there is no dependence from s2 to s1/ so after distribution(it

Hi,       I am trying to debug R on fedora9.0. When I use gdb to debug R-1.9.2, I am getting the error "R: error while loading shared libraries: libRblas.so: cannot open shared object file: No such file or directory" "Program exited with code 0177. Missing separate debuginfos, use: debuginfo-install glibc.i686" I have libRblas.so shared library in two paths, 1)

Hi, I am using "line" function to plot the line. And I would like to understand "Tukeyline" algorithm. Since, the line function is calling the Tukeyline algorithm(which is compiled code) using foreign function interface, I am not able to look into the source code of this algorithm. Can somebody help me out, so that I can refer the same. Thanks in advance!!! Thanks,

Are LoopPasses allowed to maintain state between runOnLoop invocations? The documentation is not clear on this point. -Dave

I now understand that IndVarSimplify.cpp is capable of reproducing array references when the pointer initialization from the array address is found inside the immediately enclosing loop, such that in the following code: int A[20000], B[100], Z; int main() { int i, j, *a, *b; for ( a = &A[0], i = 0; i != 200; i++ ) for ( b = &B[0], j = 0; j != 100; j++

hi all, I want access to all basic blocks of function in a loop, so I used the following code: *bool parallel::runOnLoop(Loop *L, LPPassManager &LPM) { for (Function::iterator bi= func->begin(); bi != func->end(); bi++){ // } }* First loop run without problem, but for second loop I get the following error: *0 libLLVM-2.9.so 0x0137d530 1 libLLVM-2.9.so 0x0137fa6c 2

Thank you for your reply Yes, I change them, so what should I do for another loops?

I don't really know what you should do since I don't know what your code does. All I know is that it's changing the function's control-flow graph. If you're not modifying the structure of the loops in the function, then you can

I am changing structure of loops, I used std::vector<> but i get same error, I can’t use FunctionPass :( On Mon, Dec 12, 2011 at 8:03 PM, John Criswell <criswell at illinois.edu>wrote: > On 12/12/11 10:25 AM, neda 8664 wrote: > > Thank you for your reply > Yes, I change them, so what should I do for another loops? > > > I don't really know what you should

I'm wondering if the documentation for LoopPass ( http://llvm.org/docs/WritingAnLLVMPass.html#LoopPass) is misleading or incorrect (or if I'm just missing something.) The documentation states: "The doFinalization method ... is called when the pass framework has finished calling runOnLoop<http://llvm.org/docs/WritingAnLLVMPass.html#runOnLoop> for every loop in the program being
