[MLIR][NVVM] Update mbarrier.arrive.* Op (#168758) This patch updates the mbarrier.arrive.* family of Ops to include all features added up-to Blackwell. * Update the `mbarrier.arrive` Op to include shared_cluster memory space, cta/cluster scope and an option to lower using relaxed semantics. * An `arrive_drop` variant is added for both the `arrive` and `arrive.nocomplete` operations. * Updates for expect_tx and complete_tx operations. * Verifier checks are added wherever appropriate. * lit tests are added to verify the lowering to the intrinsics. TODO: * Updates for the remaining mbarrier family will be done in subsequent PRs. (mainly, arrive.expect-tx, test_wait and try_waits) Signed-off-by: Durgadoss R <durgadossr@nvidia.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.
