[OpenMP] Update OpenMP runtime to adopt taskgraph clause from 6.0 Specs (#130751) Updating OpenMP runtime taskgraph support(record/replay mechanism): - Adds a `graph_reset` bit in `kmp_taskgraph_flags_t` to discard existing TDG records. - Switches from a strict index-based TDG ID/IDX to a more flexible integer-based, which can be any integer (e.g. hashed). - Adds helper functions like `__kmp_find_tdg`, `__kmp_alloc_tdg`, and `__kmp_free_tdg` to manage TDGs by their IDs. These changes pave the way for the integration of OpenMP taskgraph (spec 6.0). Taskgraphs are still recorded in an array with a lookup efficiency reduced to O(n), where n ≤ `__kmp_max_tdgs`. This can be optimized by moving the TDGs to a hashtable, making lookups more efficient. The provided helper routines facilitate easier future optimizations.
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.
