For historical reasons, the TYPE_FLOATFORMAT element is still set to hold
an array of two floatformat structs, one for big-endian and the other for
little-endian. When accessing the element via floatformat_from_type,
the code would check the type's byte order and return the appropriate
floatformat.
However, these days this is quite unnecessary, since the type's byte order
is already known at the time the type is allocated and the floatformat is
installed into TYPE_FLOATFORMAT. Therefore, we can just install the correct
version here.
Also, moves the (now trivially simple) floatformat_from_type accessor to
gdbtypes.{c,h}, since it doesn't really need to be in doublest.c now.
gdb/ChangeLog
2017-09-27 Ulrich Weigand <uweigand@de.ibm.com>
* doublest.h (floatformat_from_type): Move to gdbtypes.h.
* doublest.c (floatformat_from_type): Move to gdbtypes.c.
* gdbtypes.h (union type_specific): Make field floatformat hold
just a single struct floatformat, not an array.
(floatformat_from_type): Move here.
* gdbtypes.c (floatformat_from_type): Move here. Update to
changed TYPE_FLOATFORMAT definition.
(verify_floatformat): Update to changed TYPE_FLOATFORMAT.
(recursive_dump_type): Likewise.
(init_float_type): Install correct floatformat for byte order.
(arch_float_type): Likewise.

/* * \page gdbtypes GDB Types
|
|
|
|
GDB represents all the different kinds of types in programming
|
|
languages using a common representation defined in gdbtypes.h.
|
|
|
|
The main data structure is main_type; it consists of a code (such
|
|
as #TYPE_CODE_ENUM for enumeration types), a number of
|
|
generally-useful fields such as the printable name, and finally a
|
|
field main_type::type_specific that is a union of info specific to
|
|
particular languages or other special cases (such as calling
|
|
convention).
|
|
|
|
The available type codes are defined in enum #type_code. The enum
|
|
includes codes both for types that are common across a variety
|
|
of languages, and for types that are language-specific.
|
|
|
|
Most accesses to type fields go through macros such as
|
|
#TYPE_CODE(thistype) and #TYPE_FN_FIELD_CONST(thisfn, n). These are
|
|
written such that they can be used as both rvalues and lvalues.

Regardless of the language, GDB represents multidimensional
|
|
array types the way C does: as arrays of arrays. So an
|
|
instance of a GDB array type T can always be seen as a series
|
|
of instances of TYPE_TARGET_TYPE (T) laid out sequentially in
|
|
memory.
|
|
|
|
Row-major languages like C lay out multi-dimensional arrays so
|
|
that incrementing the rightmost index in a subscripting
|
|
expression results in the smallest change in the address of the
|
|
element referred to. Column-major languages like Fortran lay
|
|
them out so that incrementing the leftmost index results in the
|
|
smallest change.
|
|
|
|
This means that, in column-major languages, working our way
|
|
from type to target type corresponds to working through indices
|
|
from right to left, not left to right. */
