re PR middle-end/81502 (In some cases the data is moved to memory unnecessarily [partial regression])
2017-07-28 Richard Biener <rguenther@suse.de>
PR tree-optimization/81502
* match.pd: Add pattern combining BIT_INSERT_EXPR with
BIT_FIELD_REF.
* tree-cfg.c (verify_expr): Verify types of BIT_FIELD_REF
size/pos operands.
(verify_gimple_assign_ternary): Likewise for BIT_INSERT_EXPR pos.
* gimple-fold.c (maybe_canonicalize_mem_ref_addr): Use bitsizetype
for BIT_FIELD_REF args.
* fold-const.c (make_bit_field_ref): Likewise.
* tree-vect-stmts.c (vectorizable_simd_clone_call): Likewise.
* gcc.target/i386/pr81502.c: New testcase.
