And that is why I used the same compiler for all ISA's: gcc 12.2.0. The GIMPLE IR intermediate product is the same for all architectures; however, the ISA backend is specific to each ISA, so code generation peculiarities might or might not be an issue. GCC code output quality is above the average or high for all active mainstream architectures. Also, RISC-V compressed instructions are RISC-V 32-bit, therefore a comparison with 64-bit architectures is not applicable.
