[PATCH V2 0/3] RISC-V: Add an experimental vector calling convention

2023-08-10 Thread Lehua Ding
Hi RISC-V folks, This patch implement the proposal of RISC-V vector calling convention[1] and this feature can be enabled by `--param=riscv-vector-abi` option. Currently, all vector type arguments and return values are pass by reference. With this patch, these arguments and return values can pass
