From 49b2387b7d746d23b791f4daeb755bf1e35abe3e Mon Sep 17 00:00:00 2001 From: chenxiaolong Date: Fri, 29 Dec 2023 09:45:15 +0800 Subject: [PATCH] LoongArch: testsuite:Fix FAIL in lasx-xvstelm.c file. After implementing the cost model on the LoongArch architecture, the GCC compiler code has this feature turned on by default, which causes the lasx-xvstelm.c file test to fail. Through analysis, this test case can generate vectorization instructions required for detection only after disabling the functionality of the cost model with the "-fno-vect-cost-model" compilation option. gcc/testsuite/ChangeLog: * gcc.target/loongarch/vector/lasx/lasx-xvstelm.c:Add compile option "-fno-vect-cost-model" to dg-options. --- gcc/testsuite/gcc.target/loongarch/vector/lasx/lasx-xvstelm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/testsuite/gcc.target/loongarch/vector/lasx/lasx-xvstelm.c b/gcc/testsuite/gcc.target/loongarch/vector/lasx/lasx-xvstelm.c index 1a7b0e86f8ba..4b846204a657 100644 --- a/gcc/testsuite/gcc.target/loongarch/vector/lasx/lasx-xvstelm.c +++ b/gcc/testsuite/gcc.target/loongarch/vector/lasx/lasx-xvstelm.c @@ -1,5 +1,5 @@ /* { dg-do compile } */ -/* { dg-options "-O3 -mlasx" } */ +/* { dg-options "-O3 -mlasx -fno-vect-cost-model" } */ /* { dg-final { scan-assembler-times "xvstelm.w" 8} } */ #define LEN 256 -- 2.47.2
