[OFFLOAD][L0] Expose native ELF to upper layers (#172819) This PR refactors how the device image is built so we can expose the native ELF of the device to DeviceImageTy which solves several issues regarding symbol look up (as DeviceImageTy expects an ELF). It also simplifies the module linking code taking into account the latest changes in the driver (which adds "-library-compilation when necessary). --------- Co-authored-by: Alexey Sachkov <alexey.sachkov@intel.com> Co-authored-by: Nick Sarnie <nick.sarnie@intel.com> Co-authored-by: Joseph Huber <huberjn@outlook.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.
