`global_load_lds` and `buffer_load to lds` do only increment `vmcnt` and not touch `lgkmcnt`. This causes invalid `waitcnts` for some Triton kernels, similar to the added lit tests. Note that the change for buffer ops is not necesssary, i.e. the lit test passes even before this PR, because it seems like `SIInsertWaitcnts` does not use `LGKM_CNT` for buffer ops. But this change might prevent a bug in the future.
The LLVM Compiler Infrastructure
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.
