27
28 GDB represents all the different kinds of types in programming
29 languages using a common representation defined in gdbtypes.h.
30
31 The main data structure is main_type; it consists of a code (such
71e50e83 32 as #TYPE_CODE_ENUM for enumeration types), a number of
5e3a2c38 33 generally-useful fields such as the printable name, and finally a
71e50e83
YQ
34 field main_type::type_specific that is a union of info specific to
35 particular languages or other special cases (such as calling
36 convention).
5e3a2c38 37
71e50e83 38 The available type codes are defined in enum #type_code. The enum
5e3a2c38
SS
39 includes codes both for types that are common across a variety
40 of languages, and for types that are language-specific.
41
71e50e83
YQ
42 Most accesses to type fields go through macros such as
43 #TYPE_CODE(thistype) and #TYPE_FN_FIELD_CONST(thisfn, n). These are
44 written such that they can be used as both rvalues and lvalues.

93 Regardless of the language, GDB represents multidimensional
94 array types the way C does: as arrays of arrays. So an
95 instance of a GDB array type T can always be seen as a series
96 of instances of TYPE_TARGET_TYPE (T) laid out sequentially in
97 memory.
98
99 Row-major languages like C lay out multi-dimensional arrays so
100 that incrementing the rightmost index in a subscripting
101 expression results in the smallest change in the address of the
102 element referred to. Column-major languages like Fortran lay
103 them out so that incrementing the leftmost index results in the
104 smallest change.
105
106 This means that, in column-major languages, working our way
107 from type to target type corresponds to working through indices
108 from right to left, not left to right. */
