This patch introduces enhancements to the Baremetal toolchain to support GCC toolchain detection. - If the --gcc-install-dir or --gcc-toolchain options are provided and point to valid paths, the sysroot is derived from those locations. - If not, the logic falls back to the existing sysroot inference mechanism already present in the Baremetal toolchain. - Support for adding include paths for the libstdc++ library has also been added. Additionally, the restriction to always use the integrated assembler has been removed. With a valid GCC installation, the GNU assembler can now be used as well. This patch currently updates and adds tests for the ARM target only. RISC-V-specific tests will be introduced in a later patch, once the RISCVToolChain is fully merged into the Baremetal toolchain. At this stage, there is no way to test the RISC-V target within this PR. RFC: https://discourse.llvm.org/t/merging-riscvtoolchain-and-baremetal-toolchains/75524
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:
