* exceptions.h (NOT_AVAILABLE_ERROR): New error. * value.c: Include "exceptions.h". (require_available): Throw NOT_AVAILABLE_ERROR instead of a generic error. * cp-abi.c: Include gdb_assert.h. (baseclass_offset): Add `embedded_offset' and `val' parameters. Assert the method is implemented. Wrap NOT_AVAILABLE_ERROR errors. * cp-abi.h (baseclass_offset): Add `embedded_offset' and `val' parameters. No longer returns -1 on error. (struct cp_abi_ops) <baseclass_offset>: Add `embedded_offset' and `val' parameters. * cp-valprint.c: Include exceptions.h. (cp_print_value): Handle NOT_AVAILABLE_ERROR errors when fetching the baseclass_offset. Handle unavailable base classes. Use val_print_invalid_address. * p-valprint.c: Include exceptions.h. (pascal_object_print_value): Handle NOT_AVAILABLE_ERROR errors when fetching the baseclass_offset. No longer expect baseclass_offset returning -1. Handle unavailable base classes. Use val_print_invalid_address. * valops.c (dynamic_cast_check_1): Rename `contents' parameter to `valaddr' parameter, and change its type to gdb_byte pointer. Add `embedded_offset' and `val' parameters. Adjust. (dynamic_cast_check_2): Rename `contents' parameter to `valaddr' parameter, and change its type to gdb_byte pointer. Add `embedded_offset' and `val' parameters. Adjust. No longer expect baseclass_offset returning -1. (value_dynamic_cast): Use value_contents_for_printing rather than value_contents. Adjust. (search_struct_field): No longer expect baseclass_offset returning -1. (search_struct_method): If reading memory from the target is necessary, wrap it in a new value to pass to baseclass_offset. No longer expect baseclass_offset returning -1. (find_method_list): No longer expect baseclass_offset returning -1. Use value_contents_for_printing rather than value_contents. * valprint.c (val_print_invalid_address): New function. * valprint.h (val_print_invalid_address): Declare. * gdbtypes.c (is_unique_ancestor_worker): New `embedded_offset' and `val' parameters. No longer expect baseclass_offset returning -1. Adjust. * gnu-v2-abi.c: Include "exceptions.h". (gnuv2_baseclass_offset): Add `embedded_offset' and `val' parameters. Handle unavailable memory. Recurse through gnuv2_baseclass_offset directly, rather than through baseclass_offset. No longer returns -1 on not found, instead throw an error. * gnu-v3-abi.c (gnuv3_baseclass_offset): Add `embedded_offset' and `val' parameters. Adjust. gdb/testsuite/ * gdb.trace/unavailable.cc (class Base, class Middle, class Derived): New types. (derived_unavail, derived_partial, derived_whole): New globals. (virtual_partial): New global. (virtualp): Point at virtual_partial. * gdb.trace/unavailable.exp (gdb_collect_globals_test): Add tests related to unavailable vptr.
