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

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
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

699 a derived class) plus one field for each class data member. Member
700 functions are recorded elsewhere.

756 For TYPE_CODE_TYPEDEF the flags of the typedef type should be

759 not specify any new qualifiers, TYPE_INSTANCE_FLAGS is 0 and the

765 /* * Length of storage for a value of this type. This is what
766 sizeof(type) would return; use it for address arithmetic, memory
767 reads and writes, etc. This size includes padding. For example,
768 an i386 extended-precision floating point value really only
769 occupies ten bytes, but most ABI's declare its size to be 12
770 bytes, to preserve alignment. A `struct type' representing such
771 a floating-point type would have a `length' value of 12, even
772 though the last two bytes are unused.
774 There's a bit of a host/target mess here, if you're concerned
775 about machines whose bytes aren't eight bits long, or who don't
776 have byte-addressed memory. Various places pass this to memcpy
777 and such, meaning it must be in units of host bytes. Various
778 other places expect they can calculate addresses by adding it
779 and such, meaning it must be in units of target bytes. For
780 some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
781 and TARGET_CHAR_BIT will be (say) 32, this is a problem.
783 One fix would be to make this field in bits (requiring that it
784 always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
785 the other choice would be to make it consistently in units of
786 HOST_CHAR_BIT. However, this would still fail to address
