[Flang] Repair intrinsic CUBLAS USE association (#217455) This is a fix targeted at the specific code berkeleygw. It adds a general extension by which imports of intrinsic functions can shadow imported user functions and adds a single exception for CUBLAS `zgemm` USE-association collision with an equivalent user external interface. When the intrinsic CUBLAS generic and an equivalent external interface are USE-associated under the same name, Flang now selects the CUBLAS generic via a default-on compatibility extension. This preserves the CUBLAS CUDA-specific overloads instead of creating an unusable local association. The repair warns by default under `-Wintrinsic-module-use-association-extension`; `-fno-intrinsic-module-use-association` retains the prior semantic error, and `-Wno-intrinsic-module-use-association-extension` suppresses the warning.
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.
