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.
/* { dg-do compile } */
-/* { dg-options "-O3 -mlasx" } */
+/* { dg-options "-O3 -mlasx -fno-vect-cost-model" } */
/* { dg-final { scan-assembler-times "xvstelm.w" 8} } */
