Clang doesn't understand -march=riscv64imac and -mcmodel=medany, so don't use them when running the clang static analyzer. On the other hand, __riscv and __riscv_xlen need to be defined in order to select some macros in src/arch/riscv/include/arch/encoding.h. __riscv_flen selects the floating-point paths in src/arch/riscv/misaligned.c. -mabi is moved with -march for consistency. A complete list of preprocessor definitions on RISC-V can be found at https://github.com/riscv/riscv-toolchain-conventions#cc-preprocessor-definitions With this commit, scan-build produces a useful result on RISC-V.
