These are a set of macros that allow the addition of additional command

line options to GDB. They are currently used only for the unsupported

i960 Nindy target, and should not be used in any other configuration.

@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)}.

|

Define this to expand into any code that you want to execute before the

main loop starts. Although this is not, strictly speaking, a target
|
|
conditional, that is how it is currently being used. Note that if a
|
|
configuration were to define it one way for a host and a different way
|
|
for the target, GDB will probably not compile, let alone run correctly.

This is currently used only for the unsupported i960 Nindy target, and

@item USE_STRUCT_CONVENTION (gcc_p, type)
|
|
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.

@item VARIABLES_INSIDE_BLOCK (desc, gcc_p)
|
|
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.
