Hi Duncan, A DragonEgg/GCC-related question: do you know where these strange FRAME tokens originate from (e.g. %struct.FRAME.matmul)? Compiling simple Fortran code with DragonEgg: > cat matmul.f90 subroutine matmul(nx, ny, nz) implicit none integer :: nx, ny, nz real, dimension(nx, ny) :: A real, dimension(ny, nz) :: B real, dimension(nx, nz) :: C integer :: i, j, k real,

Hi everyone, I'll be very thankful if anyone can help me. I want to extract the dependences details by using polly. I followed the following steps on example code matmul.c: 1. clang -S -emit-llvm matmul.c -o matmul.s 2. opt -S -polly-canonicalize matmul.s > matmul.preopt.ll 3. opt -basicaa -polly-dependences -analyze matmul.preopt.ll But it doesn't show me the dependences. I

Dear All, I've had trouble compiling DPpackage as a user in one system. It works fine as root in other machines. I can see any clues in error messages My guess is that it is a permissions matter. Any help is appreciated. OS: Linux Kernel: 2.6.27 SMP Arch: Intel 64 bits gfortran not available Thank you. ----------------------><8------------------------------------- g77 ? -fpic ?-g

What version of LLVM are you using? The profiling framework is completely messed up in the newer versions of LLVM.. I used to work with profiling in 2.5 some time ago, and it seemed to work fine.. If you really need this to work quickly, you might want to just get the old version and get on with it.. The newer versions of LLVM need to get the profiling part fixed soon..It is messing up my work as

Dear all, I have already checked some related posted messages, such as: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-January/012315.html and http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-February/012466.html After getting rid of some error messages, I was able to run the following commands: 1) opt -insert-path-profiling matmul.bc -o matmul.pp.bc 2) lli -load

Hi, I have a problem - looking for advice. I have a source code file with two functions which are compiled into a .bc file. When the bitcode file is loaded, I can dump the module and see the two functions: ... ; Materializable ; Function Attrs: noinline nounwind uwtable define void @matmul(double*, double*, double*, i32, i32, i32) #0 {} ; Materializable ; Function Attrs: noinline nounwind

I am writing a function in fortran 95, but the intrinsic function MATMUL is not working properly. Here's an example. SUBROUTINE mymult(x,y,res,m,n) IMPLICIT NONE INTEGER :: m,n REAL :: x, y, res DIMENSION :: x(m,n), y(n,m), res(m,m) res = MATMUL(x,y) END SUBROUTINE mymult R CMD SHLIB mat.f95 In R: dyn.load("mat.so") x <-

I just checkout release_38 branches of llvm, clang and polly and built it on and x86 Ubuntu with cmake: CMAKE_BUILD_TYPE="Debug" CMAKE_INSTALL_PREFIX="$HOME/toolchain/install/llvm-3.8" LLVM_TARGETS_TO_BUILD="X86" cmake -G "Unix Makefiles" \ -DBUILD_SHARED_LIBS="ON" \ -DCMAKE_BUILD_TYPE=$CMAKE_BUILD_TYPE \

Hello. I tried to get the trip count of a loop with Scalar evolution. I got inspired from http://stackoverflow.com/questions/13834364/how-to-get-loop-bounds-in-llvm . However the analysis described there doesn't work well for the second inner loop of thes function below (although if we declare Bcols a short it works well): void MatMul(int Arows, int Acols, int Brows, int

Hi, I am trying to use GDB for debugging my llvm pass. I am following the documentation http://llvm.org/docs/WritingAnLLVMPass.html. When i am doing this the following error and warning messages I am getting. I tried to remove the warning by apt-get install libc6-dbg:i386 command for updating the libc6 but still getting the same.

Hi, all I tried Polly installation on Ubuntu. On its building, it returned no errors. But when I run "make polly-test", it returns 11 unexpected failures as follows. ----------------------------------- ******************** Testing Time: 19.77s ******************** Failing Tests (11): Polly :: CodeGen/do_pluto_matmult.ll Polly :: CodeGen/loop_with_condition.ll Polly ::

According to comment in tree-nested.c, these frames should be only introduced in case of debug or OpenMP lowering: /* A subroutine of convert_nonlocal_reference_op. Create a local variable in the nested function with DECL_VALUE_EXPR set to reference the true variable in the parent function. This is used both for debug info and in OpenMP lowering. */ However, in this code example we

After a lot of testing and help from Duncan, Benjamin, Joerg and others, I think the new SROA is ready for some broader testing. I've fixed all the crashers and miscompiles that Duncan and Joerg have been able to find (although I'm sure there are a few left I'll tackle when there are reports), and the LNT numbers look *really* good. Here is the latest LNT run we got by flipping it on

When running irlba on a big.matrix as in the example from the vignette (on Windows R 2.15.2 64 bit) it returns with an error (see below). irlba works fine on a regular R matrix > library(bigalgebra) > library(irlba) Loading required package: Matrix Loading required package: lattice > matmul <- function(A, x, transpose=FALSE) + { + if(transpose) {return(t( t(x) %*% A))}# i.e.,

I know that there is one serious bug that would impact in BE system. I should have that fixed today, along with a crasher. I would appreciate help tracking down any issues once the one I
