re PR debug/77589 (fortran: Missing DW_AT_byte_stride for an array record field selection)
PR debug/77589
include/
* dwarf2.def (DW_OP_GNU_variable_value): New opcode.
gcc/
* dwarf2out.c (struct dw_loc_list_struct): Add noted_variable_value
bitfield.
(size_of_loc_descr): Handle DW_OP_GNU_variable_value.
(output_loc_operands): Handle DW_OP_call_ref and
DW_OP_GNU_variable_value.
(struct variable_value_struct): New type.
(struct variable_value_hasher): Likewise.
(variable_value_hash): New variable.
(string_types): Remove.
(copy_loc_descr): New function.
(add_loc_descr_to_each): Clarify comment. Use copy_loc_descr.
(prepend_loc_descr_to_each): New function.
(add_loc_list): Fix comment typo. Use prepend_loc_descr_to_each
instead of add_loc_descr_to_each if the first argument is single
location list and the second has multiple.
(resolve_args_picking_1): Handle DW_OP_GNU_variable_value.
(loc_list_from_tree_1): For early_dwarf, emit DW_OP_GNU_variable_value
when looking for variable value which doesn't have other location info.
(loc_list_from_tree): Formatting fix.
(gen_array_type_die): Simplify DW_AT_string_length handling.
(adjust_string_types): Remove.
(gen_subprogram_die): Don't call adjust_string_types nor test/set
string_types. Call resolve_variable_values.
(prune_unused_types_walk_loc_descr): Handle DW_OP_GNU_variable_value.
(resolve_addr_in_expr): Likewise. Add A argument.
(copy_deref_exprloc): Remove deref argument. Adjust for the
original expression being DW_OP_GNU_variable_value with optionally
DW_OP_stack_value after it instead of DW_OP_call4 with DW_OP_deref
optionally after it.
(optimize_string_length): Rework for DW_OP_GNU_variable_value.
(resolve_addr): Adjust optimize_string_length and resolve_addr_in_expr
callers. Set remove_AT_byte_size if removing DW_AT_string_length.
(variable_value_hasher::hash, variable_value_hasher::equal): New
methods.
(resolve_variable_value_in_expr, resolve_variable_value,
resolve_variable_values, note_variable_value_in_expr,
note_variable_value): New functions.
(dwarf2out_early_finish): Call note_variable_value on all toplevel
DIEs.
