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

94 of instances of TYPE_TARGET_TYPE (T) laid out sequentially in
97 Row-major languages like C lay out multi-dimensional arrays so
98 that incrementing the rightmost index in a subscripting
99 expression results in the smallest change in the address of the
100 element referred to. Column-major languages like Fortran lay
101 them out so that incrementing the leftmost index results in the

754 occupies ten bytes, but most ABI's declare its size to be 12
755 bytes, to preserve alignment. A `struct type' representing such
756 a floating-point type would have a `length' value of 12, even

762 and such, meaning it must be in units of host bytes. Various
763 other places expect they can calculate addresses by adding it
764 and such, meaning it must be in units of target bytes. For
765 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
766 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
768 One fix would be to make this field in bits (requiring that it
769 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
770 the other choice would be to make it consistently in units of
