From 247cacc9e381d666a492dfa4ed61b7b19e2d008f Mon Sep 17 00:00:00 2001 From: Pan Li Date: Tue, 7 Mar 2023 20:05:15 +0800 Subject: [PATCH] RISC-V: Bugfix for rvv bool mode precision adjustment Fix the bug of the rvv bool mode precision with the adjustment. The bits size of vbool*_t will be adjusted to [1, 2, 4, 8, 16, 32, 64] according to the rvv spec 1.0 isa. The adjusted mode precison of vbool*_t will help underlying pass to make the right decision for both the correctness and optimization. Given below sample code: void test_1(int8_t * restrict in, int8_t * restrict out) { vbool8_t v2 = *(vbool8_t*)in; vbool16_t v5 = *(vbool16_t*)in; *(vbool16_t*)(out + 200) = v5; *(vbool8_t*)(out + 100) = v2; } Before the precision adjustment: addi a4,a1,100 vsetvli a5,zero,e8,m1,ta,ma addi a1,a1,200 vlm.v v24,0(a0) vsm.v v24,0(a4) // Need one vsetvli and vlm.v for correctness here. vsm.v v24,0(a1) After the precision adjustment: csrr t0,vlenb slli t1,t0,1 csrr a3,vlenb sub sp,sp,t1 slli a4,a3,1 add a4,a4,sp sub a3,a4,a3 vsetvli a5,zero,e8,m1,ta,ma addi a2,a1,200 vlm.v v24,0(a0) vsm.v v24,0(a3) addi a1,a1,100 vsetvli a4,zero,e8,mf2,ta,ma csrr t0,vlenb vlm.v v25,0(a3) vsm.v v25,0(a2) slli t1,t0,1 vsetvli a5,zero,e8,m1,ta,ma vsm.v v24,0(a1) add sp,sp,t1 jr ra However, there may be some optimization opportunates after the mode precision adjustment. It can be token care of in the RISC-V backend in the underlying separted PR(s). gcc/ChangeLog: PR target/108185 PR target/108654 * config/riscv/riscv-modes.def (ADJUST_PRECISION): Adjust VNx*BI modes. * config/riscv/riscv.cc (riscv_v_adjust_precision): New. * config/riscv/riscv.h (riscv_v_adjust_precision): New. * genmodes.cc (adj_precision): New.
