- 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 disagreement 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.
