efriedma added a comment.
Given this is an on-by-default warning already, I don't expect changing it to
an error by default to have much impact in practice. Changing it fine.
================
Comment at: clang/lib/Sema/SemaExprCXX.cpp:8483
+ if ((SemaRef.getLangOpts().CPlusPlus && Trap.hasErrorOccurred()) ||
+ Res.isInvalid())
return ExprError();
----------------
I'd prefer not to introduce unnecessary differences in C vs. C++ handling like
this...
This seems weird for two reasons:
- We don't use ext_typecheck_convert_pointer_int in C++, so there's not really
any reason to mark it SFINAEFailure
- Whatever code is calling this probably doesn't want an SFINAE context. Is
this coming from TransformToPotentiallyEvaluated? We don't want SFINAE traps
from there, in C or C++.
