Fix up NOP_EXPR operand. (vectorizable_store): Handle masked scatters with decl and integral mask type. (permute_vec_elements): Allow scalar_dest to be NULL. * config/i386/i386.c (ix86_get_builtin) <case IX86_BUILTIN_GATHER3ALTDIV16SF>: Use lowpart_subreg for masks. <case IX86_BUILTIN_GATHER3ALTDIV8SF>: Don't assume mask and src have to be the same. * gcc.target/i386/avx512f-pr88462-1.c: Rename to ... * gcc.target/i386/avx512f-pr88464-1.c: ... this. Fix up PR number. Expect 4 vectorized loops instead of 3. (f4): New function. * gcc.target/i386/avx512f-pr88462-2.c: Rename to ... * gcc.target/i386/avx512f-pr88464-2.c: ... this. Fix up PR number and #include. (avx512f_test): Prepare arguments for f4 and check the results. * gcc.target/i386/avx512f-pr88464-3.c: New test. * gcc.target/i386/avx512f-pr88464-4.c: New test.
