1934 Some object file formats (ELF, COFF, etc) do not define fundamental
1935 types such as "int" or "double". Others (stabs for example), do
1936 define fundamental types.
1937
1938 For the formats which don't provide fundamental types, gdb can create
1939 such types, using defaults reasonable for the current language and
1940 the current target machine.
1941
1942 NOTE: This routine is obsolescent. Each debugging format reader
1943 should manage it's own fundamental types, either creating them from
1944 suitable defaults or reading them from the debugging information,
1945 whichever is appropriate. The DWARF reader has already been
1946 fixed to do this. Once the other readers are fixed, this routine
1947 will go away. Also note that fundamental types should be managed
1948 on a compilation unit basis in a multi-language environment, not

3463 /* NOTE: on some targets, addresses and pointers are not necessarily
3464 the same --- for example, on the D10V, pointers are 16 bits long,
3465 but addresses are 32 bits long. See doc/gdbint.texinfo,
3466 ``Pointers Are Not Always Addresses''.
3467
3468 The upshot is:
3469 - gdb's `struct type' always describes the target's
3470 representation.
3471 - gdb's `struct value' objects should always hold values in
3472 target form.
3473 - gdb's CORE_ADDR values are addresses in the unified virtual
3474 address space that the assembler and linker work with. Thus,
3475 since target_read_memory takes a CORE_ADDR as an argument, it
3476 can access any memory on the target, even if the processor has
3477 separate code and data address spaces.
3478
3479 So, for example:
3480 - If v is a value holding a D10V code pointer, its contents are
3481 in target form: a big-endian address left-shifted two bits.
3482 - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as
3483 sizeof (void *) == 2 on the target.
3484
3485 In this context, builtin_type_CORE_ADDR is a bit odd: it's a
3486 target type for a value the target will never see. It's only
3487 used to hold the values of (typeless) linker symbols, which are
3488 indeed in the unified virtual address space. */
