| 219 | // macro. | |||

| 222 | // Decl::getLocation() returns the place where the macro is being called. | |||

| 224 | // then we want to map Decl::getLocation() into the macro to where the | |||
| 225 | // declaration and its attached comment (if any) were written. | |||
| 226 | // | |||
| 227 | // This mapping into the macro is done by mapping the location to its | |||
| 228 | // spelling location, however even if the declaration is inside a macro, | |||
| 229 | // the name's spelling can come from a macro argument (case 2 above). In | |||
| 230 | // this case mapping the location to the spelling location finds the | |||
| 231 | // argument's position (at `f` in MAKE_METHOD(`f`) above), which is not | |||
| 232 | // where the declaration and its comment are located. | |||
| 233 | // | |||
| 234 | // To avoid this issue, we make use of Decl::getBeginLocation() instead. | |||
| 235 | // While the declaration's position is where the name is written, the | |||
| 236 | // comment is always attached to the begining of the declaration, not to | |||
| 237 | // the name. | |||
| 238 | // | |||
| 239 | // In the first case, the begin location of the decl is outside the macro, | |||
| 240 | // at the location of `typedef`. This is where the comment is found as | |||
| 241 | // well. The begin location is not inside a macro, so it's spelling | |||
| 242 | // location is the same. | |||
| 243 | // | |||
| 244 | // In the second case, the begin location of the decl is the call to the | |||
| 245 | // macro, at `MAKE_METHOD`. However its spelling location is inside the | |||
| 246 | // the macro at the location of `void`. This is where the comment is found | |||
| 247 | // again. | |||
| 248 | // | |||
| 249 | // In the third case, there's no correct single behaviour. We want to use | |||
| 250 | // the comment outside the macro for the definition that's inside the macro. | |||
| 251 | // There is also a definition outside the macro, and we want the comment to | |||
| 252 | // apply to both. The cases we care about here is NS_ENUM() and | |||
| 253 | // NS_OPTIONS(). In general, if an enum is defined inside a macro, we should | |||
| 254 | // try to find the comment there. | |||
