Many apps fail to build under LLVM toolchain #15
Description
I've been working on adding LLVM toolchain support to the RISC-V build system.
However, many applications currently fail to build under LLVM due to code issues such as:
- unused variables (e.g. in malloc.c)
- incompatible attributes like __maybe_unused (e.g. in pipe.c)
- general incompatibility with Clang (e.g. cpubench.c)
In #14 I have addressed some minor issues to make the build system itself functional under LLVM.
However, resolving all code-level incompatibilities across applications is beyond my current scope, as it involves modifying application logic and behavior.
Therefore, I kindly request to ensure LLVM compatibility across all applications once the LLVM build system support is complete.
