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 main_type::type_specific that is a union of info specific to
35 particular languages or other special cases (such as calling
38 The available type codes are defined in enum #type_code. The enum
39 includes codes both for types that are common across a variety
40 of languages, and for types that are language-specific.
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

96 of instances of TYPE_TARGET_TYPE (T) laid out sequentially in
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

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