From 44f244e4672578be6cc513104473981790a1c164 Mon Sep 17 00:00:00 2001 From: Juzhe-Zhong Date: Wed, 12 Jul 2023 23:24:38 +0800 Subject: [PATCH] RISC-V: Support COND_LEN_* patterns This middle-end has been merged: https://github.com/gcc-mirror/gcc/commit/0d4dd7e07a879d6c07a33edb2799710faa95651e With this patch, we can handle operations may trap on elements outside the loop. These 2 following cases will be addressed by this patch: 1. integer division: #define TEST_TYPE(TYPE) \ __attribute__((noipa)) \ void vrem_##TYPE (TYPE * __restrict dst, TYPE * __restrict a, TYPE * __restrict b, int n) \ { \ for (int i = 0; i < n; i++) \ dst[i] = a[i] % b[i]; \ } #define TEST_ALL() \ TEST_TYPE(int8_t) \ TEST_ALL() Before this patch: vrem_int8_t: ble a3,zero,.L14 csrr t4,vlenb addiw a5,a3,-1 addiw a4,t4,-1 sext.w t5,a3 bltu a5,a4,.L10 csrr t3,vlenb subw t3,t5,t3 li a5,0 vsetvli t6,zero,e8,m1,ta,ma .L4: add a6,a2,a5 add a7,a0,a5 add t1,a1,a5 mv a4,a5 add a5,a5,t4 vl1re8.v v2,0(a6) vl1re8.v v1,0(t1) sext.w a6,a5 vrem.vv v1,v1,v2 vs1r.v v1,0(a7) bleu a6,t3,.L4 csrr a5,vlenb addw a4,a4,a5 sext.w a5,a4 beq t5,a4,.L16 .L3: csrr a6,vlenb subw t5,t5,a4 srli a6,a6,1 addiw t1,t5,-1 addiw a7,a6,-1 bltu t1,a7,.L9 slli a4,a4,32 srli a4,a4,32 add t0,a1,a4 add t6,a2,a4 add a4,a0,a4 vsetvli a7,zero,e8,mf2,ta,ma sext.w t3,a6 vle8.v v1,0(t0) vle8.v v2,0(t6) subw t4,t5,a6 vrem.vv v1,v1,v2 vse8.v v1,0(a4) mv t1,t3 bltu t4,t3,.L7 csrr t1,vlenb add a4,a4,a6 add t0,t0,a6 add t6,t6,a6 sext.w t1,t1 vle8.v v1,0(t0) vle8.v v2,0(t6) vrem.vv v1,v1,v2 vse8.v v1,0(a4) .L7: addw a5,t1,a5 beq t5,t1,.L14 .L9: add a4,a1,a5 add a6,a2,a5 lb a6,0(a6) lb a4,0(a4) add a7,a0,a5 addi a5,a5,1 remw a4,a4,a6 sext.w a6,a5 sb a4,0(a7) bgt a3,a6,.L9 .L14: ret .L10: li a4,0 li a5,0 j .L3 .L16: ret After this patch: vrem_int8_t: ble a3,zero,.L5 .L3: vsetvli a5,a3,e8,m1,tu,ma vle8.v v1,0(a1) vle8.v v2,0(a2) sub a3,a3,a5 vrem.vv v1,v1,v2 vse8.v v1,0(a0) add a1,a1,a5 add a2,a2,a5 add a0,a0,a5 bne a3,zero,.L3 .L5: ret 2.
