Previously, since response (.rsp) files weren't expanded at the very beginning of clang-scan-deps, we only parsed the command-line as provided in the Clang .cdb file. Unfortunately, when using Unreal Engine, arguments are always generated in a .rsp file (ie. `/path/to/clang-cl.exe @/path/to/filename_args.rsp`). After this patch, `/Fo` can be parsed and added to the final command-line. Without this option, the make targets that are emitted are made up from the input file name alone. We have some cases where the same input in the project generates several output files, so we end up with duplicate make targets in the scan-deps emitted dependency file.
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.
