Hi Juzhe,
Thanks for taking the time to review the code. I will address comments 1, 2, 3.
For comment 4, it is necessary to implement these hooks. The purpose is to

that they can be recognized by the linker. Send the V

Hi, this patch is to add LEN_MASK_STORE into SCCVN.
LEN_MASK_STORE is predicated by both len and mask together.
My understanding is that LEN_MASK_STORE has same rhs_off and offset as

The size = MIN (length (deduced from mask), (len + bias)).

Hi, previous I made a mistake on GIMPLE_FOLD of LEN_MASK_{LOAD,STORE}.
We should fold LEN_MASK_{LOAD,STORE} (bias+len) == vf (nunits instead of

into:
MEM_REF [...].
This patch added testcase to test gimple fold of LEN_MASK_{LOAD,STORE}.

When there're multiple operands in vec_oprnds0, vec_dest will be
overwrited to vectype_out, but in multi_step_cvt case, cvt_type is
expected. It caused an ICE when verify_gimple_in_cfg.
