Gordon reminded me that most people seem to generate code using code, whereas it has become natural for me to use templates to generate code. Let me include an example from an article I'm working on (Java centric). The same argument goes for LLVM IR templates versus using the C++ interface. Generating LLVM IR for me is super simple. Here are a few of my templates for generating IR

Hi Terence, The reason I remarked, actually, is that for LLVM in particular the C+ + API offers more safety, and emitting .ll generally requires at least partially reimplementing the IR object model. I think this is a topic in the FAQ. But both are perfectly valid approaches! - Gordon On Apr 23, 2008, at 14:04, Terence Parr <parrt at cs.usfca.edu> wrote: > Gordon reminded me that

Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to

I ran into an LLVM/Clang crash when attempting to do the following: 1. Build Clang from the release/9.x branch source. 2. Use the Clang from (1) to build clangd on the release/9.x branch, with LLVM_ENABLE_MODULES=On. I wrote a script to reproduce the crash: https://gist.github.com/modocache/ac366ca9673b93bb21e75d3e72162608 At the above URL, you'll find a script `repro.sh` that reproduces

Dear all, In the process of trying to add optimization for better layout of global variables, I have run up against a roadblock: I don`t seem to be able to sort the contents of a "SymbolTableListTraits<GlobalVariable>" -- or even swap two elements in that list -- without causing LLVM to crash. I have tried writing a comparator class and then using "llvm::iplist<

I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to
