In each case, the + change is because the new calls provide enough information to do + the appropriate address / pointer conversions, where the old calls + did not, or because the new functions are more appropriately named + for the operation being performed. + + * ax-gdb.c (const_var_ref): Use value_from_pointer, not + value_from_longest. + * blockframe.c (generic_push_dummy_frame): Use read_pc and + read_sp, not read_register. + * c-valprint.c (c_val_print): Use extract_typed_address instead of + extract_address to extract vtable entries and references. + * cp-valprint.c (cp_print_value_fields): Use value_from_pointer + instead of value_from_longest to extract the vtable's address. + * eval.c (evaluate_subexp_standard): Use value_from_pointer + instead of value_from_longest to compute `this', and for doing + pointer-to-member dereferencing. + * findvar.c (read_register): Use extract_unsigned_integer, not + extract_address. + (read_var_value): Use store_typed_address instead of store_address + for building label values. + (locate_var_value): Use value_from_pointer instead of + value_from_longest. + * hppa-tdep.c (find_stub_with_shl_get): Use value_from_pointer, + instead of value_from_longest, to build arguments to __d_shl_get. + * printcmd.c (set_next_address): Use value_from_pointer, not + value_from_longest. + (x_command): Use value_from_pointer, not value_from_longest. + * tracepoint.c (set_traceframe_context): Use value_from_pointer, + not value_from_longest. + * valarith.c (value_add, value_sub): Use value_from_pointer, not + value_from_longest. + * valops.c (find_function_in_inferior, value_coerce_array, + value_coerce_function, value_addr, hand_function_call): Same. + * value.h (COERCE_REF): Use unpack_pointer, not unpack_long. + * values.c (unpack_long): Use extract_typed_address to produce + addresses from pointers and references, not extract_address. + (value_from_longest): Use store_typed_address instead of + store_address to produce pointer and reference values. + 2000-04-13 Mark Kettenis <kettenis@gnu.org> * acconfig.h (HAVE_PRGREGSET_T, HAVE_PRFPREGSET_T, HAVE_LWPID_T, |
