* test/CodeGen/builtins.c: reinstate #ifdef __x86_64__ around __builtin_longjmpMehdi Amini2016-10-241-0/+5

* Fix test on non-X86 platformsMehdi Amini2016-10-241-0/+5
| | | | | | | This is a fixup for r285019, adding an `#ifdef __x86_64__` since the os_log builtin is platform specific. llvm-svn: 285027
* CodeGen: centralise label construction for method listsSaleem Abdulrasool2016-10-241-59/+107
| | | | | | | | | | | Move all the label construction for the various method list emission into EmitMethodList. Rather than have all the names be constructed in pieces in all of the callers of EmitMethodList, have this occur in one site. This also makes the calls much easier to understand as we simplify identify the type of the method list being emitted and the interface name for which it is being emitted. NFC. llvm-svn: 285023

* Add support for __builtin_os_log_format[_buffer_size]Mehdi Amini2016-10-2415-95/+995
| | | | | | | | | | | | | | | | | This reverts commit r285007 and reapply r284990, with a fix for the opencl test that I broke. Original commit message follows: These new builtins support a mechanism for logging OS events, using a printf-like format string to specify the layout of data in a buffer. The _buffer_size version of the builtin can be used to determine the size of the buffer to allocate to hold the data, and then __builtin_os_log_format can write data into that buffer. This implements format checking to report mismatches between the format string and the data arguments. Most of this code was written by Chris Willmore.

The particular test case added here is actually being mishandled: the implicit member access should not be type-dependent (because it's accessing a non-type-dependent member of the current instantiation), but calls to a type-dependent operator-> that is a member of the current instantiation would be liable to hit the same codepath. llvm-svn: 284999

* [analyzer] Add StdLibraryFunctions checker.Artem Dergachev2016-10-245-0/+1146
| | | | | | | | | | | | | | | This checker does not emit reports, however it influences the analysis by providing complete summaries for, or otherwise improving modeling of, various standard library functions. This should reduce the number of infeasible paths explored during analysis. The custom function summary format used in this checker is superior to body farms by causing less unnecessary state splits, which would result in better analysis performance.

* [Sema][TreeTransform] Re-create DesignatedInitExpr when a field designatorAlex Lorenz2016-10-242-0/+44
| | | | | | | | | | | | | | | | | | has no field declaration. This commit fixes an invalid Winitializer-overrides warning that's shown when analyzing a second (or any after the first) instantiation of a designated initializer. This invalid warning is fixed by making sure that a DesignatedInitExpr is rebuilt by the tree transformer when it has a field designator whose FieldDecl* hasn't been yet initialized. This ensures that a different DesignatedInitExpr is processed by Sema for every instantiation, and thus the invalid warning is avoided. rdar://28768441 Differential Revision: https://reviews.llvm.org/D25777 llvm-svn: 284959

Allow reference binding of a reference-to-non-noexcept function to a noexcept function lvalue.

* DR583, DR1512: Implement a rewrite to C++'s 'composite pointer type' rules.Richard Smith2016-10-2129-216/+574
| | | | | | | | | | | | | | | | | | | | | | | | | | This has two significant effects: 1) Direct relational comparisons between null pointer constants (0 and nullopt) and pointers are now ill-formed. This was always the case for C, and it appears that C++ only ever permitted by accident. For instance, cases like nullptr < &a are now rejected. 2) Comparisons and conditional operators between differently-cv-qualified pointer types now work, and produce a composite type that both source pointer types can convert to (when possible). For instance, comparison between 'int **' and 'const int **' is now valid, and uses an intermediate type of 'const int *const *'. Clang previously supported #2 as an extension. We do not accept the cases in #1 as an extension. I've tested a fair amount of code to check that this doesn't break it, but if it turns out that someone is relying on this, we can easily add it back as an extension. This is a re-commit of r284800. llvm-svn: 284890
* Switch SmallSetVector to use DenseSet when it overflows its inline space.Justin Lebar2016-10-214-7/+12
| | | | | | | | | | | | | | | | | | | | Summary: SetVector already used DenseSet, but SmallSetVector used std::set. This leads to surprising performance differences. Moreover, it means that the set of key types accepted by SetVector and SmallSetVector are quite different! In order to make this change, we had to convert some callsites that used SmallSetVector<std::string, N> to use SmallSetVector<CachedHashString, N> instead.
