After the detection procedure under the gcc.dg/vect directory was added to
GCC, FAIL entries of vector multiplication transformations of different types
appeared in the gcc regression test results. After debugging analysis, the main
problem is that the 128-bit vector of LoongArch architecture does not realize
this function. To solve this problem, the "-mlasx" option is used to enable the
256-bit vectorization implementation.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/bb-slp-pattern-1.c:If you are testing on the
LoongArch architecture, you need to add the "-mlasx" compilation
option to generate vectorized code.
* gcc.dg/vect/slp-widen-mult-half.c:Dito.
* gcc.dg/vect/vect-widen-mult-const-s16.c:Dito.
* gcc.dg/vect/vect-widen-mult-const-u16.c:Dito.
* gcc.dg/vect/vect-widen-mult-half-u8.c:Dito.
* gcc.dg/vect/vect-widen-mult-half.c:Dito.
* gcc.dg/vect/vect-widen-mult-u16.c:Dito.
* gcc.dg/vect/vect-widen-mult-u8-s16-s32.c:Dito.
* gcc.dg/vect/vect-widen-mult-u8-u32.c:Dito.
* gcc.dg/vect/vect-widen-mult-u8.c:Dito.
