I've added a link to the new page where it used to say "it's out of the scope of this document [ProgrammersManual.html] to describe how to do this". Is that close enough? When I get around to Sphinxifying ProgrammersManual.html, I think the general approach is g...

http://llvm.org/docs/ProgrammersManual.html#BasicBlock "This class represents a single entry multiple exit section of the code, commonly known as a basic block by the compiler community." This should perhaps read 'single entry single exit'?

Hi, Is there any description of the type system of LLVM more detailed than ProgrammersManual.html ? I am a newbie to LLVM and I spent quite some time browsering the source code trying to truly understand the type resolution example in the ProgrammersManual.html (e.g. Why "NewSTy" is potentially invalidated, how StrutTy is updated,etc). So I think a documentation on the overall...

Hi. I need to write a function pass that insert nop instruction in function. Examples of these instructions are: %nop = add i1 0, 0 or %nop = alloca i1, i1 0. This link couldn't help me: http://llvm.org/docs/ProgrammersManual.html#creating-and-inserting-new-instructions I need a clear example about inserting new instruction. Anyone can help me?

Hello all, I am new to the llvm infrastructure so if this question is already resolved please redirect me to that link. I am writing a pass for flow sensitive and context sensitive alias analysis.for that i require the previous and next instruction of all the instructions.Is there an intrinsic that can help me getting the instruction numbers directly because i read at the llvm.org website making

...n the patch is to use this "on the stack, where a "small" number of elements are expected". Vec<T> is a convenience alias for SmallVector<T, 0>. It lets us get the (little-known?) benefits of SmallVector even when it has no inline elements (see https://llvm.org/docs/ProgrammersManual.html#llvm-adt-smallvector-h). The recommendation in the patch is to use this when the SmallVector is on the heap. A lot of this is boiled out from the discussion in https://groups.google.com/g/llvm-dev/c/q1OyHZy8KVc/m/1l_AasOLBAAJ?pli=1 The goals here are twofold: 1. convenience: not having to r...

Hi, I'm trying to speed up the JIT time with llvm (3.9.1). So far i've implemented the object cache, used FastISel and disabled optimizations. Jit time is still too slow for my purpose (I do have a lot of code to Jit). http://llvm.org/docs/ProgrammersManual.html#threads-and-the-jit states that we can invoke ExecutionEngine::getPointerToFunction() concurrently. This function was replaced by ExecutionEngine::getFunctionAddress(). Is this function also thread safe? I want to speed up codegen by invoking parallel calls to getfunctionaddress(). Currently...

Hi, I need to find out all the places where the value of a variable is being used. For this I have to implement reaching definitions(def-use chains). When I searched for its implementation I found Iterating over def-use & use-def chains <http://llvm.org/docs/ProgrammersManual.html#iterate_chains>. will this work for finding the places where a variable is reaching? I tried to use "use_iterator", but couldn't make it out. Is it a must to write LLVM Pass to use op_iterator and use_iterator? please give me any references or examples to understand more abou...

Does inst_iterator (http://llvm.org/docs/ProgrammersManual.html#iterating-over-the-instruction-in-a-function) guarantee that the iterated instructions are in program order: the order of instructions printed by llvm-dis? Thanks in advance, Anirudh

I'm not sure whether i should add it to set like containers, or add a section about bitsets that talks about bitvector and sparsebitvector. In either case, I think this...
