26 | /* * \page gdbtypes GDB Types |
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. | |

101 | Regardless of the language, GDB represents multidimensional | |
102 | array types the way C does: as arrays of arrays. So an | |
103 | instance of a GDB array type T can always be seen as a series | |
104 | of instances of TYPE_TARGET_TYPE (T) laid out sequentially in | |
105 | memory. | |
106 | ||
107 | Row-major languages like C lay out multi-dimensional arrays so | |
108 | that incrementing the rightmost index in a subscripting | |
109 | expression results in the smallest change in the address of the | |
110 | element referred to. Column-major languages like Fortran lay | |
111 | them out so that incrementing the leftmost index results in the | |
112 | smallest change. | |
113 | ||
114 | This means that, in column-major languages, working our way | |
115 | from type to target type corresponds to working through indices | |
116 | from right to left, not left to right. */ | |
