@item ADDR_BITS_REMOVE (addr)
If a raw machine address includes any bits that are not really part of
the address, then define this macro to expand into an expression that
zeros those bits in @var{addr}.  For example, the two low-order bits of
a Motorola 88K address may be used by some kernels for their own
purposes, since addresses must always be 4-byte aligned, and so are of
no use for addressing.  Those bits should be filtered out with an
expression such as @code{((addr) & ~3)}.

slot, GDB will single-step over that instruction before resuming

These change the behavior of @code{read_pc}, @code{write_pc},

For most targets, these may be left undefined.  GDB will call the read
and write register functions with the relevant @code{_REGNUM} argument.

These macros are useful when a target keeps one of these registers in a
hard to get at place; for example, part in a segment register and part
in an ordinary register.

If defined, this must be an expression that is nonzero if a value of the
given @var{type} being returned from a function must have space
allocated for it on the stack.  @var{gcc_p} is true if the function
being considered is known to have been compiled by GCC; this is helpful
for systems where GCC is known to use different calling convention than
other compilers.

For dbx-style debugging information, if the compiler puts variable
declarations inside LBRAC/RBRAC blocks, this should be defined to be
nonzero.  @var{desc} is the value of @code{n_desc} from the
@code{N_RBRAC} symbol, and @var{gcc_p} is true if GDB has noticed the
presence of either the @code{GCC_COMPILED_SYMBOL} or the
@code{GCC2_COMPILED_SYMBOL}.  By default, this is 0.
