* Rename register FP to S0.Andreas Fried2021-04-06
| | | | | | S0 is the name preferred by GNU tools, and the only name accepted by the bare-metal assembler (riscv{32,64}-unknown-elf-as). This gives us less descriptive register names, but more portability.
* riscv: add support for variadic functionsJohannes Bucher2019-10-24
| | | | | | lowering of builtin va_arg still uses the be_default_lower_va_arg function which is not correct due to the alignment requirements of variadic arguments; a RISC-V specific implementation is needed

| | | | fp is an alternative ABI name for register s0
