Hi, I am trying to build clang, however the build size is quite large. As clang supports non-C family languages as well ( e.g. Java, Fortran ), is there a way to turn that off during the build. I just want to have support for C and C++ and don't care about other languages. Is there a CMake option that needs to be set to do that?? Thanks a lot! Best Regards, Nitish ‌ -------------- next

Hi everyone, I wanted to assign a new pragma for loops in clang. Let's call it "#pragma XXX" which can be applied to any loop in the entire loop hierarchy. I added the support for my pragma by following the same steps as were being used in the default implementation of "unroll" pragma. But now, when I compile any program using clang to llvm IR it attaches the pragma

hi R help group, I have installed PLS package in R and use it for princomp & prcomp commands for calculating PCA using its example file(USArrests example). But How I can use PLS for Partial least square, R square, mvrCv one more think how i can import external file in R. When I use plsr, R2, RMSEP it show error could not find function plsr, RMSEP etc. How I can calculate PLS, R2, RMSEP, PCR,

Hi, I want to calculate PLS package in R. Now I want to calculate R, MSEP, RMSEP and R2 of PLSR and PCR using this. I also add this in library of R. How I can calculate R, MSEP, RMSEP and R2 of PLSR and PCR in R. I s any other method then please also suggest me. Simply I want to calculate these value. Thanking you. -- Nitish Kumar Mishra Junior Research Fellow BIC, IMTECH, Chandigarh, India

Hi, Transform/LoopStrengthReduction/post-inc-icmpzero.ll was failing for clang-native-arm-cortex-a9 build-bot configuration. The reason for the failure was the test was using hardcoded names. The attached patch fixes this failure by replacing the hard-coded variables names with pattern-matched variable names. I have checked that the test pass after applying the patch. Could somebody please

Hi Manish, Thanks for the patch, I'll check and commit. cheers, --renato PS: Patches are normally sent to llvm-commit list, unless they require a lot of discussion.

Dear all, Hi! Recently, I try to combine the passes SeparateConstOffsetFromGEP and LoopStrengthReduction to transform the multiplication in the lowered GEP IRs into addition. However, it seems LoopStrengthReduction is unable to remove all the multiplications for the element offset calculation. My test code is shown below and thanks a lot in advance for your time and suggestion!

Hi Renato, Thanks! I will make sure the patches are posted to the correct mailing list.

Hi, I did the Pass ID workaround by providing Passes.h in the include/llvm/Machine. But the question which is holding me up is that, as Ken Dyck was kind enough to point out, what should be done to the dependency on libAnalysis? The Machine passes are not only dependent on Passes class but also on others such as the ConstantFolding.h. Is it a possible solution to break this dependency or carry

Hello Sir/Mam I am Nitish Kumar Mishra from IMTECH, Chandigarh, India. I want to calculate the Principal Component Analysis(PCA), PLS of the input file and find top 30 PCAs of this file using PLS in R. I am asking regarding Linux(Red Hat 9) operating system. I have downloaded PLS from Crains site and try to installed it, but don't installed it. How I can download and installed PLS(for PCA and

Hi, I've prototyped a pair of passes which 1) add synthetic debug info to a Module and 2) determine how much of that info is lost. The idea is to make it easier to write targeted test cases for debug info preservation. For example, here is a quick way to test that Mem2Reg doesn't drop debug info from one test input: > ; RUN: opt < %s -debugify -mem2reg -check-debugify -S

Hi, I would like to propose, based on a previous discussion on llvm-dev, the following change. https://reviews.llvm.org/D56337 The main motivation for annotating member functions of ADT clases with LLVM_ALWAYS_INLINE was that of speeding up `check-llvm` at `-O0`. Turns out this significantly degrades the debuggability of fundamental classes in llvm itself, e.g. StringRef or SmallVector. After
