/* Create a fundamental C type using default reasonable for the current
target machine.
Some object/debugging file formats (DWARF version 1, COFF, etc) do not
define fundamental types such as "int" or "double". Others (stabs or
DWARF version 2, etc) do define fundamental types. For the formats which
don't provide fundamental types, gdb can create such types using this
function.
FIXME: Some compilers distinguish explicitly signed integral types
(signed short, signed int, signed long) from "regular" integral types
(short, int, long) in the debugging information. There is some dis-
agreement as to how useful this feature is. In particular, gcc does
not support this. Also, only some debugging formats allow the
distinction to be passed on to a debugger. For now, we always just
use "short", "int", or "long" as the type name, for both the implicit
and explicitly signed types. This also makes life easier for the
gdb test suite since we don't have to account for the differences
in output depending upon what the compiler and debugging format
support. We will probably have to re-examine the issue when gdb
starts taking it's fundamental type information directly from the
debugging information supplied by the compiler. fnf@cygnus.com */
