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

734 an i386 extended-precision floating point value really only
735 occupies ten bytes, but most ABI's declare its size to be 12
736 bytes, to preserve alignment. A `struct type' representing such
737 a floating-point type would have a `length' value of 12, even
738 though the last two bytes are unused.

741 about machines whose bytes aren't eight bits long, or who don't
742 have byte-addressed memory. Various places pass this to memcpy
743 and such, meaning it must be in units of host bytes. Various
744 other places expect they can calculate addresses by adding it
745 and such, meaning it must be in units of target bytes. For
746 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
747 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
749 One fix would be to make this field in bits (requiring that it
750 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
751 the other choice would be to make it consistently in units of
752 HOST_CHAR_BIT. However, this would still fail to address
