cfgloop.h (struct loop): Add simdlen member.
* cfgloop.h (struct loop): Add simdlen member.
* cfgloopmanip.c (copy_loop_info): Copy simdlen as well.
* omp-expand.c (expand_omp_simd): Set it if simdlen clause is present.
* tree-vect-loop.c (vect_analyze_loop): Pass loop->simdlen != 0
as new argument to autovectorize_vector_sizes target hook. If
loop->simdlen, pick up vector size where the vectorization factor
is equal to loop->simd, and if there is none, fall back to the first
successful one.
(vect_transform_loop): Adjust autovectorize_vector_sizes target hook
caller.
* omp-low.c (omp_clause_aligned_alignment): Likewise.
* omp-general.c (omp_max_vf): Likewise.
* optabs-query.c (can_vec_mask_load_store_p): Likewise.
* tree-vect-slp.c (vect_slp_bb): Likewise.
* target.def (autovectorize_vector_sizes): Add ALL argument and
document it.
* doc/tm.texi: Adjust documentation.
* targhooks.c (default_autovectorize_vector_sizes): Add bool argument.
* targhooks.h (default_autovectorize_vector_sizes): Likewise.
* config/aarch64/aarch64.c (aarch64_autovectorize_vector_sizes): Add
bool argument.
* config/arc/arc.c (arc_autovectorize_vector_sizes): Likewise.
* config/arm/arm.c (arm_autovectorize_vector_sizes): Likewise.
* config/mips/mips.c (mips_autovectorize_vector_sizes): Likewise.
* config/i386/i386.c (ix86_autovectorize_vector_sizes): Likewise. If
true and TARGET_AVX512F or TARGET_AVX, push 3 or 2 sizes even if
preferred vector size is not 512-bit or 256-bit, just put those
unpreferred ones last.
* gcc.target/i386/avx512f-simd-1.c: New test.
