r13-1764-g5f59d0f2d9fa92
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org

commit 5f59d0f2d9fa921c04d75c39592e603cfa2b1324

Improve SLP codegen, avoiding unnecessary TREE_ADDRESSABLE
The following adjusts vectorizer code generation to avoid splitting
out address increments for invariant addresses which causes objects
to get TREE_ADDRESSABLE when not necessary.
* tree-vect-data-refs.cc (bump_vector_ptr): Return an
invariant updated address when the input was invariant.

tree-optimization/106387 - properly create SSA name for realigned load
The following fixes an oversight triggering after the recent change
to bump_vector_ptr.
PR tree-optimization/106387
* tree-vect-stmts.cc (vectorizable_load): Use make_ssa_name
if ptr is not an SSA name.
