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. From-SVN: r191302
