similar to: Computing loop trip counts with Scalar evolution

In https://bugs.llvm.org/show_bug.cgi?id=38011 (see also https://reviews.llvm.org/D48721) a problem was revealed related to llvm.loop metadata. The fault was that clang added the !llvm.loop metadata to branches outside of the loop (not only the loop latch). That was not handled properly by some opt passes (simplifying cfg) since it ended up merging branch instructions with different !llvm.loop

Hi all, Looking for tips on how I might more optimally solve this. I have time series data (samples from a force sensor) that are not guaranteed to be sampled at the same time values across trials. ex. trial time x 1 1 1 1 5 4 1 7 9 1 12 20 2 1 0 2 3 5 2 9 10 2 13 14 2 19 22 2 24 32 Within each trial I'd like to use linear interpolation between each successive time sample to fill in

Hi, When I test "matmul" in the polly directory, I get the following performance data: //=============================== --> 12. Compare the runtime of the executables time ./matmul.normalopt.exe 0:23.53 real, 23.48 user, 0.00 sys time ./matmul.polly.interchanged.exe 0:22.86 real, 22.82 user, 0.01 sys time ./matmul.polly.interchanged+tiled.exe 0:22.87 real, 22.83 user, 0.00 sys

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 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

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'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.

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

Dear r-help list members, I am quite new to R, and hope to seek advice from you about a problem I have been cracking my head over. Apologies if this seems like a simple problem. I have essentially two tables. The first (Table A) is a standard patient clinicopathological data table, where rows correspond to patient IDs and columns correspond to clinical features. Records in this table are stored

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 \

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.

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 <-

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 ::

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

I have tried multiple different methods to figure out how to get a date axis of my preference (start date of each month). Any assistance would be appreciated. The below section is not producing a date axis: plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Emax),xaxt="n") *xlabels<-(strptime(totaldays$totaldays,"%Y-%m-%d",tz=""))
