Looks reasonable. Have you tried on any large codebases? You relax two guards,
so I would be wary of explosion in false positives.
================
Comment at: lib/StaticAnalyzer/Checkers/ConversionChecker.cpp:77
if (Opc == BO_Assign) {
- LossOfSign = isLossOfSign(Cast, C);
- LossOfPrecision = isLossOfPrecision(Cast, Cast->getType(), C);
+ if (!B->getRHS()->isIntegerConstantExpr(C.getASTContext())) {
+ LossOfSign = isLossOfSign(Cast, C);
----------------
Sorry, I don't quite follow: why we don't want to warn when RHS is an integer
constant?
