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

92 Regardless of the language, GDB represents multidimensional

94 instance of a GDB array type T can always be seen as a series
95 of instances of TYPE_TARGET_TYPE (T) laid out sequentially in
98 Row-major languages like C lay out multi-dimensional arrays so
99 that incrementing the rightmost index in a subscripting
100 expression results in the smallest change in the address of the
101 element referred to. Column-major languages like Fortran lay
102 them out so that incrementing the leftmost index results in the

764 an i386 extended-precision floating point value really only
765 occupies ten bytes, but most ABI's declare its size to be 12
766 bytes, to preserve alignment. A `struct type' representing such
767 a floating-point type would have a `length' value of 12, even

773 and such, meaning it must be in units of host bytes. Various
774 other places expect they can calculate addresses by adding it
775 and such, meaning it must be in units of target bytes. For
776 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
777 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
779 One fix would be to make this field in bits (requiring that it
780 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
781 the other choice would be to make it consistently in units of
