185 | Some object/debugging file formats (DWARF version 1, COFF, etc) do not | |
186 | define fundamental types such as "int" or "double". Others (stabs or | |
187 | DWARF version 2, etc) do define fundamental types. For the formats which | |

191 | FIXME: Some compilers distinguish explicitly signed integral types | |
192 | (signed short, signed int, signed long) from "regular" integral types | |
193 | (short, int, long) in the debugging information. There is some dis- | |
194 | agreement as to how useful this feature is. In particular, gcc does | |
195 | not support this. Also, only some debugging formats allow the | |
196 | distinction to be passed on to a debugger. For now, we always just | |
197 | use "short", "int", or "long" as the type name, for both the implicit | |
198 | and explicitly signed types. This also makes life easier for the | |
199 | gdb test suite since we don't have to account for the differences | |
200 | in output depending upon what the compiler and debugging format | |
201 | support. We will probably have to re-examine the issue when gdb | |
202 | starts taking it's fundamental type information directly from the | |
203 | debugging information supplied by the compiler. fnf@cygnus.com */ | |
