re PR rtl-optimization/44194 (struct returned by value generates useless stores)
PR rtl-optimization/44194
* calls.c (expand_call): In the PARALLEL case, copy the return value
into pseudos instead of spilling it onto the stack.
* emit-rtl.c (adjust_address_1): Rename ADJUST into ADJUST_ADDRESS and
add new ADJUST_OBJECT parameter.
If ADJUST_OBJECT is set, drop the underlying object if it cannot be
proved that the adjusted memory access is still within its bounds.
(adjust_automodify_address_1): Adjust call to adjust_address_1.
(widen_memory_access): Likewise.
* expmed.c (store_bit_field_1): Call adjust_bitfield_address instead
of adjust_address. Do not drop the underlying object of a MEM.
(store_fixed_bit_field): Likewise.
(extract_bit_field_1): Likewise. Fix oversight in recursion.
(extract_fixed_bit_field): Likewise.
* expr.h (adjust_address_1): Adjust prototype.
(adjust_address): Adjust call to adjust_address_1.
(adjust_address_nv): Likewise.
(adjust_bitfield_address): New macro.
(adjust_bitfield_address_nv): Likewise.
* expr.c (expand_assignment): Handle a PARALLEL in more cases.
(store_expr): Likewise.
(store_field): Likewise.
* dse.c: Fix typos in the head comment.
