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

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
