| − | Some kernels are provided with the standard release of the NuPlus toolchain. We provide makefile to compile these kernels for NuPlus. In case you want to add a new kernel, it is suggested to copy a kernel folder and replace C/CPP files with your own source code. Then, remember to modify the makefile updating the SRCS variable with the current main C/CPP filename. When using these makefiles, different tools are called:
| |
| − | * Clang to emit the LLVM IR and the object files
| |
| − | * LLD/MCLINKER to handle the job of linking
| |
| − | * elf2hex to generate the HEX file from the ELF file
| |
| − | * llvm-objdump to generate the dump from the elf file
| |
| − | In order to change the optimization level of the compiler or any other flag, it is possible to modify the /misc/NuPlus.mk file.

| − | Adding a new target architecture, i.e. nu+, to llvm requires four steps:
| |
| − | * [[Backend|write all backend files and place them into the lib/Target/NuPlus folder]]
| |
| − | * [[Frontend|modify the Clang frontend]]
