Rémi Denis-Courmont	f59a767ccd	lavu/riscv: helper macro for VTYPE encoding ... On most cases, the vector type (VTYPE) for the RISC-V Vector extension is supplied as an immediate value, with either of the VSETVLI or VSETIVLI instructions. There is however a third instruction VSETVL which takes the vector type from a general purpose register. That is so the type can be selected at run-time. This introduces a macro to load a (valid) vector type into a register. The syntax follows that of VSETVLI and VSETIVLI, with element size, group multiplier, then tail and mask policies.	2022-10-10 02:22:12 +02:00
