This changes the GDB compile code to use std::vector<bool> when computing which registers are used. This is a bit more idiomatic, but the main benefit is that it also adds some checking when the libstd++ debug mode is enabled. 2021-01-23 Tom Tromey <tom@tromey.com> * symtab.h (struct symbol_computed_ops) <generate_c_location>: Change type of "registers_used". * dwarf2/loc.h (dwarf2_compile_property_to_c): Update. * dwarf2/loc.c (dwarf2_compile_property_to_c) (locexpr_generate_c_location, loclist_generate_c_location): Change type of "registers_used". * compile/compile.h (compile_dwarf_expr_to_c) (compile_dwarf_bounds_to_c): Update. * compile/compile-loc2c.c (pushf_register_address) (pushf_register, do_compile_dwarf_expr_to_c) (compile_dwarf_expr_to_c, compile_dwarf_bounds_to_c): Change type of "registers_used". * compile/compile-c.h (generate_c_for_variable_locations): Update. * compile/compile-c-symbols.c (generate_vla_size) (generate_c_for_for_one_variable): Change type of "registers_used". (generate_c_for_variable_locations): Return std::vector. * compile/compile-c-support.c (generate_register_struct): Change type of "registers_used". (compute): Update.
