* dwarf2.h (DW_OP_GNU_const_type, DW_OP_GNU_regval_type,
DW_OP_GNU_deref_type, DW_OP_GNU_convert, DW_OP_GNU_reinterpret): New.
* dwarf2out.c (get_address_mode): New inline.
(mem_loc_descriptor): Add MEM_MODE parameter, adjust recursive calls,
if not dwarf_strict emit
DW_OP_GNU_{{const,regval,deref}_type,convert,reinterpret} when
desirable. Handle FLOAT_EXTEND, FLOAT_TRUNCATE, FLOAT,
UNSIGNED_FLOAT, FIX and UNSIGNED_FIX. Just return NULL for
FMA, STRICT_LOW_PART, CONST_VECTOR and CONST_FIXED.
(dwarf2out_frame_debug_cfa_expression, reg_loc_descriptor,
dw_loc_list_1, cst_pool_loc_descr, loc_list_from_tree): Adjust
mem_loc_descriptor callers.
(dwarf_stack_op_name, size_of_loc_descr, output_loc_operands,
output_loc_operands_raw, hash_loc_operands, compare_loc_operands):
Handle DW_OP_GNU_const_type, DW_OP_GNU_regval_type,
DW_OP_GNU_deref_type, DW_OP_GNU_convert and DW_OP_GNU_reinterpret.
(base_types): New variable.
(get_base_type_offset, calc_base_type_die_sizes,
base_type_for_mode, mark_base_types, base_type_cmp,
move_marked_base_types): New functions.
(calc_die_sizes): Assert that die_offset is 0 or equal to
next_die_offset.
(loc_descriptor): Only handle here lowpart SUBREGs of REG, for
others defer to mem_loc_descriptor. Adjust mem_loc_descriptor
callers. If not dwarf_strict, call mem_loc_descriptor even for
non-MODE_INT modes or MODE_INT modes larger than DWARF2_ADDR_SIZE.
(gen_subprogram_die): Don't give up on call site parameters
with non-integral or large integral modes. Adjust
mem_loc_descriptor callers.
(prune_unused_types): Call prune_unused_types_mark on base_types
vector entries.
(resolve_addr): Call mark_base_types.
(dwarf2out_finish): Call move_marked_base_types.
