[OpenMP] Remove NVPTX local addrspace on parameters (#183195) In CGOpenMPRuntimeGPU::translateParameter, reference-type captured variables were translated to pointer parameters with two address-space annotations: 1. LangAS::opencl_global on the pointee (for map'd variables), which correctly produces ptr addrspace(1) in NVPTX IR. 2. getLangASFromTargetAS(NVPTX_local_addr=5) on the pointer itself, annotating the parameter as living in NVPTX local (stack) memory. The second annotation is incorrect at the Clang type-system level: EmitParmDecl only supports parameters to be in LangAS::Default (or the special cases for OpenCL). Temporarily add an assert in EmitParmDecl that catches parameters with non-default address spaces in non-OpenCL compilations, and fix the violation by dropping the NVPTX_local_addr addAddressSpace call. Should fix the issue noticed in https://github.com/llvm/llvm-project/pull/181256#discussion_r2821894122, allowing removing that special case there for OpenMP, though I haven't tested the combination yet. That PR would fix EmitParmDecl to actually support non-default address spaces from Sema, and will remove this assert again. Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
