@section Configuring the current ABI
|
||||
|
||||
@value{GDBN} can determine the @dfn{ABI} (Application Binary Interface) of your
|
||||
application automatically. However, sometimes you need to override its
|
||||
conclusions. Use these commands to manage @value{GDBN}'s view of the

current ABI.

@cindex float promotion
|
||||
@kindex set coerce-float-to-double
|
||||
|
||||
Generally, the way that an argument of type @code{float} is passed to a
|
||||
function depends on whether the function is prototyped. For a prototyped
|
||||
(i.e.@: ANSI/ISO style) function, @code{float} arguments are passed unchanged,
|
||||
according to the architecture's convention for @code{float}. For unprototyped
|
||||
(i.e.@: K&R style) functions, @code{float} arguments are first promoted to type
|
||||
@code{double} and then passed.
|
||||
|
||||
Unfortunately, some forms of debug information do not reliably indicate whether
|
||||
a function is prototyped. If @value{GDBN} calls a function that is not marked
|
||||
as prototyped, it consults @kbd{set coerce-float-to-double}.
|
||||
|
||||
@table @code
|
||||
@item set coerce-float-to-double
|
||||
@itemx set coerce-float-to-double on
|
||||
Arguments of type @code{float} will be promoted to @code{double} when passed
|
||||
to an unprototyped function. This is the default setting.
|
||||
|
||||
@item set coerce-float-to-double off
|
||||
Arguments of type @code{float} will be passed directly to unprototyped

functions.

@cindex passing arguments to prototyped functions

Return non-zero if GDB should promote @code{float} values to
|
||||
@code{double} when calling a non-prototyped function. The argument
|
||||
@var{actual} is the type of the value we want to pass to the function.
|
||||
The argument @var{formal} is the type of this argument, as it appears in
|
||||
the function's definition. Note that @var{formal} may be zero if we
|
||||
have no debugging information for the function, or if we're passing more
|
||||
arguments than are officially declared (for example, varargs). This
|
||||
macro is never invoked if the function definitely has a prototype.
|
||||
|
||||
How you should pass arguments to a function depends on whether it was
|
||||
defined in K&R style or prototype style. If you define a function using
|
||||
the K&R syntax that takes a @code{float} argument, then callers must
|
||||
pass that argument as a @code{double}. If you define the function using
|
||||
the prototype syntax, then you must pass the argument as a @code{float},
|
||||
with no promotion.
|
||||
|
||||
Unfortunately, on certain older platforms, the debug info doesn't
|
||||
indicate reliably how each function was defined. A function type's
|
||||
@code{TYPE_FLAG_PROTOTYPED} flag may be unset, even if the function was
|
||||
defined in prototype style. When calling a function whose
|
||||
@code{TYPE_FLAG_PROTOTYPED} flag is unset, GDB consults the
|
||||
@code{COERCE_FLOAT_TO_DOUBLE} macro to decide what to do.
|
||||
|
||||
@findex standard_coerce_float_to_double
|
||||
For modern targets, it is proper to assume that, if the prototype flag
|
||||
is unset, that can be trusted: @code{float} arguments should be promoted
|
||||
to @code{double}. You should use the function
|
||||
@code{standard_coerce_float_to_double} to get this behavior.
|
||||
|
||||
@findex default_coerce_float_to_double
|
||||
For some older targets, if the prototype flag is unset, that doesn't
|
||||
tell us anything. So we guess that, if we don't have a type for the
|
||||
formal parameter (@i{i.e.}, the first argument to
|
||||
@code{COERCE_FLOAT_TO_DOUBLE} is null), then we should promote it;
|
||||
otherwise, we should leave it alone. The function
|
||||
@code{default_coerce_float_to_double} provides this behavior; it is the
|
||||
default value, for compatibility with older configurations.

/* Functions to use for the COERCE_FLOAT_TO_DOUBLE gdbarch method.
|
||||
|
||||
How you should pass arguments to a function depends on whether it
|
||||
was defined in K&R style or prototype style. If you define a
|
||||
function using the K&R syntax that takes a `float' argument, then
|
||||
callers must pass that argument as a `double'. If you define the
|
||||
function using the prototype syntax, then you must pass the
|
||||
argument as a `float', with no promotion.
|
||||
|
||||
Unfortunately, on certain older platforms, the debug info doesn't
|
||||
indicate reliably how each function was defined. A function type's
|
||||
TYPE_FLAG_PROTOTYPED flag may be clear, even if the function was
|
||||
defined in prototype style. When calling a function whose
|
||||
TYPE_FLAG_PROTOTYPED flag is clear, GDB consults the
|
||||
COERCE_FLOAT_TO_DOUBLE gdbarch method to decide what to do.
|
||||
|
||||
For modern targets, it is proper to assume that, if the prototype
|
||||
flag is clear, that can be trusted: `float' arguments should be
|
||||
promoted to `double'. You should register the function
|
||||
`standard_coerce_float_to_double' to get this behavior.
|
||||
|
||||
For some older targets, if the prototype flag is clear, that
|
||||
doesn't tell us anything. So we guess that, if we don't have a
|
||||
type for the formal parameter (i.e., the first argument to
|
||||
COERCE_FLOAT_TO_DOUBLE is null), then we should promote it;
|
||||
otherwise, we should leave it alone. The function
|
||||
`default_coerce_float_to_double' provides this behavior; it is the
|
||||
default value, for compatibility with older configurations. */
