Compiling C code for fox32

How does this work?

• GCC compiles your C code with riscv*-gcc -S hello.c -march=rv32im -mabi=ilp32 -O2
• rv2fox converts the generated RISC-V assembly to fox32 assembly
• fox32asm makes an FXF binary

TODO:

• commandline argument passing
• calls out of C, into the ROM
• testcase sha256 program that hashes the ROM
• rust support: rustc --emit asm --target riscv32im-unknown-none-elf test.rs -O
