similar to: [LLVMdev] llvm::DenseSet with reverse iterator

Something that might interest you is the SetVector, which as its name implies is both a set and a vector paired together. You get the advantage of doing set-like operations (search) on the set and vector-like operations (iteration, random access) on the vector, but at the cost of paying the price for both data structures when modifying the structure (and double the memory). This seems like it

Reverse iteration doesn't really make sense for DenseSet, since its iteration order isn't meaningful to begin with... --Owen On Jul 12, 2012, at 8:20 AM, Vassil Vassilev wrote: > Hi, > I need a data structure which has fast search and I can walk it > forward and backward.

Hi, Thanks a lot for the help! It seems that the SmallSetVector is the ADT I need (interface-wise). Is more efficient than llvm::UniqueVector? In my use case I have to insert a new element in the structure only if the element is unique. I hardly expect more than 32 elements. Do you think I gain a lot if I use the SmallSetVector instead of using SmallVector + slow searching on every

UniqueVector is an stl map coupled with an stl vector[1], which seems very undesirable for you. As far as SmallVector + slow search, I believe that is precisely what the implementation of SmallSet does until it has to grow, after which it uses an stl set[2]. If you're always staying within your small number, SmallSetVector would be wasteful as the SmallSet would itself also have a SmallVector.

+Easily, some of the code snippets end up being copied dozens of +times, which leads to worse maintainability, understandability and logical +design. The project description stresses code maintainability and logical design more than bug finding due to omissions in copy and pasted code. Reading this made me think of a check that would suggest people to replace copy and pasted code with a function

The list can't ommit clang-tidy.

Hi folks, Happy new year! Last LLVM Developers' Meeting I had a BoF: 'Raising Next Generation LLVM Developers'. It was suggested that we should update our open projects page and possibly restructure it a little bit. I volunteered to do this work and I need your help. Chandler and I started working on a google doc [1]. We pinged few code owners asking them to list of

Hi Matthias, Thanks a lot for the project. Could you put it in the google doc below? I'd appreciate if you could follow more-or-less the format. Are you going to be the mentor.

Dear community, We are trying to setup a BoF ( Raising Next Generation of LLVM Developers, http://sched.co/8Yzs). In our academic-oriented environments the main work force is students: undergrads, grads or PhD (rarely postdocs). Often we have limited time to bring somebody up to speed and we have to it in a productive and motivating for both parties way. I believe most of you had

Hi, Isn't clang::CodeGenOptions::EmitDeclMetadata what you need?

Here are two minor patches. The first adds an insert method to DenseSet that takes two iterators representing the beginning and ending of a range of items to insert. I lifted the code verbatim from DenseMap.h. The second patch defines DenseMapInfo for chars. This is useful because DenseSet is implemented as a DenseMap of (Type, char), so anyone who uses DenseSet has to define DenseMapInfo for

Dear All, On Wednesday, October 23 at 5 pm we will have a roundtable about LLVM's participation in GSoC and similar programs: http://llvm.org/devmtg/2019-10/#round The list of topics includes: - Overall organization of the project (timeline, ideas, etc) - Ideas lists - Lessons learned from past projects More topics for discussion are welcome! -- With best regards, Anton Korobeynikov
