re PR tree-optimization/78675 (ICE: verify_gimple failed (error: integral result type precision does not match field size of BIT_FIELD_REF))
2016-12-06 Jakub Jelinek <jakub@redhat.com>
PR tree-optimization/78675
* tree-vect-loop.c (vectorizable_live_operation): For
VECTOR_BOOLEAN_TYPE_P vectype use integral type with bitsize precision
instead of TREE_TYPE (vectype) for the BIT_FIELD_REF.
* gcc.c-torture/execute/pr78675.c: New test.
* gcc.target/i386/pr78675-1.c: New test.
* gcc.target/i386/pr78675-2.c: New test.
