similar to: LLVM possible projects

@Vivek, thanks for your answer and especially these links! I just want to add two more though I am not sure if they are useful here: - Some slides [0] that explain the general structure of LLVM and LLVM-IR I used in our compiler class last year [0]. - Examples that build LLVM-IR "from scratch". These were designed to help students to build an LLVM-IR frontend for their AST.

Thank you vivek pandya. I will try my best to do things as you mentioned.

Hello, I want to know does LLVM has support for MPI Programming Model? Can we do LLVM optimizations in MPI Programs? Regards -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20161017/dd645f09/attachment.html>

Hi all, How can one evaluate NAs in a numeric dataframe column? For example, I have a dataframe (demo) with a column of numbers and several NAs. If I write demo.df >= 10, numerals will return TRUE or FALSE, but if the value is "NA", "NA" is returned. But if I write demo.df == "NA", it returns as "NA" also. I know that I can remove NAs, but would like

Hello, Is there a analysis pass which calculates the ModRefBehaviours OnlyReadsPointerArguments and OnlyAccessesPointerArguments? I tried to find one but so far I only saw that different AA's return OnlyReadsMemory and DoesNotAccessMemory if the readonly and readnone attributes are set.

We are happy to announce that the list of accepted sessions is available online [0]. The hacker's lab will be organized similar to the one at the US 2016 meeting [1]. To this end, we rely on you to send us topics via mail: eurollvm17-orga at cs.uni-saarland.de We will then look for knowledgeable volunteers and have a selection process to determine which are most interesting for the

Hi Johannes, Actually, I'm working in the same scenario, i.e. configure + make of a benchmark/program/library like you said. I've got your point of using this script as a replacement to generate .bc files instead of a executable. That's truly helpful and has already answered my original question. Now I'm actually moving a step further. Take the same example in your reply, say, if

".... the problem Mehdi pointed out regarding the missed initializations of array elements, did you comment on that one yet?" What is the initializations of array elements question? I don't remember this question. Please refresh my memory. Thanks. I thought Mehdi's question is more about what are attributes needed for these IR-annotation for other LLVM pass to understand and

Hi Johannes, By following your directions, I can use your script as is to produce the .bc file now. Here's my command line for compiling s_sin.c into s_sin.bc file and the output: command line: ~/Downloads/newlib-2.1.0/newlib/libm/mathfp » python ~/llvm_link.py s_sin.c -I../common/ -I../../libc/include/ -o s_sin.bc output: Initiate CLANG (/path-to-clang): Options: 's_sin.c

Hal, Johannes, Thanks for the feedback. I have been digging into this a little bit more and was able to have some of this metadata being generated. Nevertheless, I am confused about the semantics of this metadata. Let me explain: I was expecting the alias metadata to complement the information that alias analysis passes compute. However, it seems that the alias information of the pointers used

Hey, I was just informed that my ScalarEvolution patch failed the lld tests on x86_64-freebsd, however on my machine x86_64-linux all tests (llvm+lld) pass for a debug as well as a release build. Furthermore, I'm a bit confused about the error message just before the segfault happens: "Unable to find lib.exe in PATH" Could somebody help me track down the problem? Thanks in

Hi, There is now an RFC for a roadmap to native vector predication support in LLVM and a prototype implementation:   https://reviews.llvm.org/D57504 The prototype demonstrates: -  Predicated vector intrinsics with an explicit mask and vector length parameter on IR level. -  First-class predicated SDNodes on ISel level. Mask and vector length are value operands. -  An incremental strategy

Hi! There are a lot of accepted but not closed revisions in Differential. Many of them were actually committed, but without Differential revision link or when it was specified in wrong way. I think will be good idea to create script which will match committed revisions with those in Differential: file list should be same and hashes of changed line could be calculated for each file. In case of
