void*.
From Philippe De Muyter <phdm@macqel.be>:
* printcmd.c (print_address_symbolic): Call `make_cleanup' with
`(free_current_contents, &x)', not `(free, x)'.
* utils.c (free_current_contents): Do not `free (NULL)'.
* printcmd.c (print_address_symbolic): Cleanup after a failed
call to build_address_symbolic.
functions which architectures can redefine, defaulting to
generic_pointer_to_address and generic_address_to_pointer.
* findvar.c (extract_typed_address, store_typed_address,
generic_pointer_to_address, generic_address_to_pointer): New
functions.
(POINTER_TO_ADDRESS, ADDRESS_TO_POINTER): Provide default
definitions.
(extract_address, store_address): Doc fixes.
* values.c (value_as_pointer): Doc fix.
(value_from_pointer): New function.
* defs.h (extract_typed_address, store_typed_address): New
declarations.
* inferior.h (generic_address_to_pointer,
generic_pointer_to_address): New declarations.
* value.h (value_from_pointer): New declaration.
* 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.
* defs.h (struct continuation_arg): make 'data' a union, to avoid
casting problems when int and pointer are not the same size.
* event-top.c (command_handler): use data as a union.
(command_line_handler_continuation): ditto.
* infcmd.c (step_1_continuation): use data as a union. Re-indent.
(step_once): ditto. (finish_command_continuation): ditto.
(finish_command): ditto.
* breakpoint.c (until_break_command): use data as a union.
(until_break_command_continuation): ditto.
* utils.c (add_intermediate_continuation): fix typo in comment.
* defs.h (struct continuation_arg): Change type of field 'data'
from PTR to void *.
* event-loop.h: Eliminate uses of PTR, use 'void *' instead.
* event-top.c: Ditto.
(error_return, quit_return): Merge into catch_return pointer.
(return_to_top_level): Update comment. Longjmp to *catch_errors,
and communicate reason to catch_errors via setjmp return value.
(catch_errors): Always catch both quit and error, and if a catch
wasn't requested by caller, throw it to the next catch_error.
Replace dual longjmp buffer memcpy with single pointer change.
Add FIXME for possibly adding new interface to tell caller what
event was caught. Add extensive comments.
* defs.h (enum return_reason): Reserve 0 for use as initial
setjmp() return value.
(RETURN_MASK): New public macro to generate RETURN_MASK_* from
enum return_reason.
(RETURN_MASK_QUIT, RETURN_MASK_ERROR): Define using RETURN_MASK.
