NoQ added a comment.
Had a fresh look on the C++ part, it is super clean now, i'm very impressed :)
================
Comment at: lib/StaticAnalyzer/Core/CallEvent.cpp:373-374
- return RuntimeDefinition();
+ auto Engine = static_cast<ExprEngine *>(
+ getState()->getStateManager().getOwningEngine());
+
----------------
*Humbly suggests to refactor whatever we need here into `SubEngine`'s virtual
method(s).
`getAnalysisManager()` is already there, so i guess we only need to expose
`getCrossTranslationUnitContext()`.
================
Comment at: lib/StaticAnalyzer/Core/CallEvent.cpp:385
+ FD, Engine->getAnalysisManager().options.getCTUDir(),
+ "externalFnMap.txt");
+
----------------
I think `CallEvent` is the last place where i'd prefer to hardcode this
filename. Maybe hardcode it in `CrossTranslationUnitContext` or get from
`AnalyzerOptions`? (the former, i guess, because i doubt anybody would ever
want to change it).
================
Comment at: lib/StaticAnalyzer/Core/PathDiagnostic.cpp:418-423
SourceLocation XDL = XD->getLocation();
SourceLocation YDL = YD->getLocation();
if (XDL != YDL) {
const SourceManager &SM = XL.getManager();
- return SM.isBeforeInTranslationUnit(XDL, YDL);
+ return compareCrossTUSourceLocs(FullSourceLoc(XDL, SM),
+ FullSourceLoc(YDL, SM));
----------------
It seems to me that `XDL` and `YDL` are exactly the same as `XL` and `YL` we've
seen at the beginning of the function.
...we still have only one `SourceManager`, right?
