912 Some object file formats (ELF, COFF, etc) do not define fundamental
913 types such as "int" or "double". Others (stabs for example), do
914 define fundamental types.
916 For the formats which don't provide fundamental types, gdb can create
917 such types, using defaults reasonable for the current target machine.
919 FIXME: Some compilers distinguish explicitly signed integral types
920 (signed short, signed int, signed long) from "regular" integral types
921 (short, int, long) in the debugging information. There is some dis-
922 agreement as to how useful this feature is. In particular, gcc does
923 not support this. Also, only some debugging formats allow the
924 distinction to be passed on to a debugger. For now, we always just
925 use "short", "int", or "long" as the type name, for both the implicit
926 and explicitly signed types. This also makes life easier for the
927 gdb test suite since we don't have to account for the differences
928 in output depending upon what the compiler and debugging format
929 support. We will probably have to re-examine the issue when gdb
