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.

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

782 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
783 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
