[clang-sycl-linker] Remove dead and unnecessary check for no symbols image (#197596) The `if (SI.Symbols.empty()) continue;` guard in `runSYCLLink` was unreachable: `collectEntryPoints` always calls `llvm::offloading::sycl::writeSymbolTable`, which emits at least a 4-byte `SymbolTableHeader` (`Count=0`) even when the input has no entry points. The check could never fire and was misleading suggesting that modules without kernels would be dropped. I checked other similar tools and did not find logic to filter out images, if there are no entry points. This doesn't look like responsibility of clang-sycl-linker. If this scenario is required, we can consider adding it later with a proper check. --------- Co-authored-by: Alexey Bader <alexey.bader@intel.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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
