gcc/ChangeLog:

instruction template corresponding to the __builtin_thread_pointer
function.

In simd_correctness_check.h, the role of the macro ASSERTEQ_64 is to check the
result of the passed vector values for the 64-bit data of each array element.
It turns out that it uses the abs() function to check only the lower 32 bits
of the data at a time, so it replaces abs() with the llabs() func
The function of this test is to check that the compiler supports vectorization
using SLP and vec_{load/store/*}_lanes. However, vec_{load/store/*}_lanes are
not supported on LoongArch, such as the corresponding "st4/ld4" directives on
aarch64.

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 f
for instruction set differences and test behavior for program Settings,
etc. For details, see the following patches:
chenxiaolong (8):
LoongArch: testsuite:Add detection procedures supported by the target.
LoongArch: testsuite:Modify the test behavior of the
vect-bic-bitmask-{12,23}.c file
In order to improve and check the function of vector quantization in
LoongArch architecture, tests on vector instruction set are provided
in target-support.exp.

In the GCC code of LoongArch architecture, IFN_STORE_LANES optimization

On the LoongArch architecture, the above four test cases need to be waived
during testing. There are two situations:

is to find the value of -(a*b -
In the GCC of LoongArch architecture, the detection function of common
vectorization test cases is enabled. The following detection procedure
is added to the target-supports.exp file:

2.check_effective_target_vect_int
3.check_effective_target_vect_intfloat_c

In the LoongArch architecture, the reason for not adding the 128-bit
vector-width-*hi* instruction template in the GCC back end is that it causes
program performance loss, so we can only add the "-mlasx" compilation option
to use 256-bit vectorization functions in test files.
gcc/testsuite/ChangeL
- Change the default vectorization "-mlasx" option to "-mlsx" because there
are many non-aligned memory accesses when using 256-bit vectorization.

1.check_effective_target_scalar_all_fma
2.check_effective_target_vect_in
