Subject: [PATCH 095/188] 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.
