Hi Bekket, I don't see any use case in the codebase adding clEnumValEnd at the end of list (for example, [1]), I also don't see there is clEnumValEnd. Do I miss something here?

Hi, The argument list for cl::values in command line library should be end with null or clEnumValEnd. But the tutorial page(http://llvm.org/docs/CommandLine.html <http://llvm.org/docs/CommandLine.html>) doesn’t follow the rule, which would cause program crash during runtime. I’d send a code review: https://reviews.llvm.org/D33861 <https://reviews.llvm.org/D33861> Please cc other

To my knowledge that intrinsic IS generated by frontends like Clang when using _builtin_return_address(), i could be wrong though Zhang > 在 2018年9月5日，10:47，Bekket McClane via llvm-dev <llvm-dev at lists.llvm.org> 写道： > > and

Hi LLVM folks, As the sequel of my blog posts shared previously: Writing LLVM Pass in 2018 - [Part I](https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-i-531c700e85eb <https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-i-531c700e85eb> ) and [Part II](https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-ii-640f680978ec

Hi, I've been studying the global instruction selector introduced recently. One of the properties of global instruction selectors is that they select instructions across basic blocks such that they can get more information in order to choose optimal patterns. However, the current global isel implementation still iterates over BBs within functions, which is same as the original SelectionDAG

Hello With LLVM 4.0 my code is being compiled correctly. but with LLVM 7.0.1 I am getting following error; *llvm-7.0.1.src/include/llvm/IR/Module.h:356:43: error: no matching constructor for initialization of 'SmallVector<llvm::Type *, sizeof...(ArgsTy)>' SmallVector<Type*, sizeof...(ArgsTy)> ArgTys{Args...};* What is the reason? Please help. Thank You

Hi, I'm new to LLVM and I'm doing research on factors of compilation time, especially instruction selection and scheduling. One of the academic papers I read, https://llvm.org/svn/llvm-project/www-pubs/trunk/2008-CGO-DagISel.pdf (Koes, David Ryan, and Seth Copen Goldstein. "Near-optimal instruction selection on dags."), which is also said to be the algorithm LLVM currently

Hi, Though there exists lots of researches on parallelizing or scheduling optimization passes, If you open up the time matrices of codegen(llc -time-passes), you'll find that the most time consuming task is actually instruction selection(40~50% of time) instead of optimization passes(10~0%). That's why we're trying to parallelize the (target-independent) instruction selection process

Hi all, I have seen in multiple cases that, usually at the beginning of the function. if a BranchInst is encountered the next block might have %0 indicated as predecessor. I think it is a way to say "no predecessors found". Am I correct? Few examples just for clarifying what I mean: define noalias %struct.png_struct_def* @png_create_read_struct_2(i8* %user_png_ver, i8* %error_ptr, void

Hi, I am trying to figure out the best way to add some extra metadata to the store and load llvm-ir instructions: The metadata content is a 'Value*' expression representing a side channel, containing dependency information that is used to help the Scoped Alias Analysis. Optimizations that don't know about this side channel can safely drop it, where the only effect would be on the
