clang: <root>/clang/lib/StaticAnalyzer/Core/SimpleSValBuilder.cpp:727: void assertEqualBitWidths(clang::ento::ProgramStateRef, clang::ento::Loc, clang::ento::Loc): Assertion `RhsBitwidth == LhsBitwidth && "RhsLoc and LhsLoc bitwidth must be same!"' This change adjusts the bitwidth of the smaller operand for an evalBinOp as a result of a comparison operation. This can occur in the specific case represented by the test cases for a target with different pointer sizes. Reviewed By: NoQ Differential Revision: https://reviews.llvm.org/D122513
