* [CodeComplete] Clearly distinguish signature help and code completion.Ilya Biryukov2018-09-075-50/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Code completion in clang is actually a mix of two features: - Code completion is a familiar feature. Results are exposed via the CodeCompleteConsumer::ProcessCodeCompleteResults callback. - Signature help figures out if the current expression is an argument of some function call and shows corresponding signatures if so. Results are exposed via CodeCompleteConsumer::ProcessOverloadCandidates. This patch refactors the implementation to untangle those two from each other and makes some naming tweaks to avoid confusion when reading the code. The refactoring is required for signature help fixes, see D51038. The only intended behavior change is the order of callbacks. ProcessOverloadCandidates is now called before ProcessCodeCompleteResults.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Negative arguments in kernel attributes are silently bitcast'ed to unsigned, for example: __attribute__((reqd_work_group_size(1, -1, 1))) __kernel void k() {} is a complete equivalent of: __attribute__((reqd_work_group_size(1, 4294967294, 1))) __kernel void k() {} This is likely an error, so the patch forbids negative arguments in several OpenCL attributes. Users who really want 4294967294 can still use it as an unsigned representation.

* PR38627: Fix handling of exception specification adjustment forRichard Smith2018-09-057-45/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | destructors. We previously tried to patch up the exception specification after completing the class, which went wrong when the exception specification was needed within the class body (in particular, by a friend redeclaration of the destructor in a nested class). We now mark the destructor as having a not-yet-computed exception specification immediately after creating it. This requires delaying various checks against the exception specification (where we'd previously have just got the wrong exception specification, and now find we have an exception specification that we can't compute yet) when those checks fire while the class is being defined. This also exposed an issue that we were missing a CodeSynthesisContext for computation of exception specifications (otherwise we'd fail to make the module containing the definition of the class visible when computing its members' exception specs). Adding that incidentally also gives us a diagnostic quality improvement. This has also exposed an pre-existing problem: making the exception specification evaluation context a non-SFINAE context (as it should be) results in a bootstrap failure; PR38850 filed for this. llvm-svn: 341499

* [x86/SLH] Add a real Clang flag and LLVM IR attribute for SpeculativeChandler Carruth2018-09-044-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Load Hardening. Wires up the existing pass to work with a proper IR attribute rather than just a hidden/internal flag. The internal flag continues to work for now, but I'll likely remove it soon. Most of the churn here is adding the IR attribute. I talked about this Kristof Beyls and he seemed at least initially OK with this direction. The idea of using a full attribute here is that we *do* expect at least some forms of this for other architectures. There isn't anything *inherently* x86-specific about this technique, just that we only have an implementation for x86 at the moment. While we could potentially expose this as a Clang-level attribute as well, that seems like a good question to defer for the moment as it isn't 100% clear whether that or some other programmer interface (or both?) would be best. We'll defer the programmer interface side of this for now, but at least get to the point where the feature can be enabled without relying on implementation details. This also allows us to do something that was really hard before: we can enable *just* the indirect call retpolines when using SLH. For x86, we don't have any other way to mitigate indirect calls. Other architectures may take a different approach of course, and none of this is surfaced to user-level flags. Differential Revision: https://reviews.llvm.org/D51157 llvm-svn: 341363
