* [analyzer] Improve VirtualCallChecker and enable parts of it by default.Artem Dergachev2019-08-208-260/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling a pure virtual method during construction or destruction is undefined behavior. It's worth it to warn about it by default. That part is now known as the cplusplus.PureVirtualCall checker. Calling a normal virtual method during construction or destruction may be fine, but does behave unexpectedly, as it skips virtual dispatch. Do not warn about this by default, but let projects opt in into it by enabling the optin.cplusplus.VirtualCall checker manually. Give the two parts differentiated warning text: Before: Call to virtual function during construction or destruction: Call to pure virtual function during construction Call to virtual function during construction or destruction: Call to virtual function during destruction After: Pure virtual method call: Call to pure virtual method 'X::foo' during construction has undefined behavior Unexpected loss of virtual dispatch: Call to virtual method 'Y::bar' during construction bypasses virtual dispatch Also fix checker names in consumers that support them (eg., clang-tidy) because we now have different checker names for pure virtual calls and regular virtual calls. Also fix capitalization in the bug category. Differential Revision: https://reviews.llvm.org/D64274 llvm-svn: 369449

* [Sema][Typo] Fix assertion failure for expressions with multiple typosDavid Goldman2019-08-204-42/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: As Typo Resolution can create new TypoExprs while resolving typos, it is necessary to recurse through the expression to search for more typos. This should fix the assertion failure in `clang::Sema::~Sema()`: `DelayedTypos.empty() && "Uncorrected typos!"` Notes: - In case some TypoExprs are created but thrown away, Sema now has a Vector that is used to keep track of newly created typos. - For expressions with multiple typos, we only give suggestions if we are able to resolve all typos in the expression - This patch is similar to D37521 except that it does not eagerly commit to a correction for the first typo in the expression. Instead, it will search for corrections which fix all of the typos in the expression. Subscribers: cfe-commits Tags: #clang Differential Revision: https://reviews.llvm.org/D62648 llvm-svn: 369427

* win: Enable /Zc:twoPhase by default if targeting MSVC 2017 update 3 or newerNico Weber2019-08-204-13/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | MSVC 2017 update 3 (_MSC_VER 1911) enables /Zc:twoPhase by default, and so should clang-cl: https://docs.microsoft.com/en-us/cpp/build/reference/zc-twophase clang-cl takes the MSVC version it emulates from the -fmsc-version flag, or if that's not passed it tries to check what the installed version of MSVC is and uses that, and failing that it uses a default version that's currently 1911. So this changes the default if no -fmsc-version flag is passed and no installed MSVC is detected. (It also changes the default if -fmsc-version is passed or MSVC is detected, and either indicates _MSC_VER >= 1911.) As mentioned in the MSDN article, the Windows SDK header files in version 10.0.15063.0 (Creators Update or Redstone 2) and earlier versions do not work correctly with /Zc:twoPhase. If you need to use these old SDKs with a new clang-cl, explicitly pass /Zc:twoPhase- to get the old behavior. Fixes PR43032. Differential Revision: https://reviews.llvm.org/D66394 llvm-svn: 369402

* Removed the 'id' AST matcher, which is superseded by '.bind()'Dmitri Gribenko2019-08-202-31/+22
| | | | | | | | | | | | | | | | | Summary: The 'id' matcher is not even included in the AST Matchers Reference document, so I don't expect there to be a significant number of users. There's no reason to provide two ways to do the exact same thing that only have a minor syntactic difference.

| | | | | | | | CGLoopInfo was keeping pointers to parent loop LoopInfos, but when the loop info vector grew, it reallocated the storage and invalidated all of the parent pointers, causing use-after-free.

* [OpenCL] Add generic type handling for builtin functionsSven van Haastregt2019-08-194-257/+613
| | | | | | | | | | | | | | | | | | Generic types are an abstraction of type sets. It mimics the way functions are defined in the OpenCL specification. For example, floatN can abstract all the vector sizes of the float type. This allows to * stick more closely to the specification, which uses generic types; * factorize definitions of functions with numerous prototypes in the tablegen file; and * reduce the memory impact of functions with many overloads.
