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 */
