* Class Property: class property and instance property can have the same name.Manman Ren2016-01-2812-55/+127
| | | | | | | | | | | | | | | | | | | Add "enum ObjCPropertyQueryKind" to a few APIs that used to only take the name of the property: ObjCPropertyDecl::findPropertyDecl, ObjCContainerDecl::FindPropertyDeclaration, ObjCInterfaceDecl::FindPropertyVisibleInPrimaryClass, ObjCImplDecl::FindPropertyImplDecl, and Sema::ActOnPropertyImplDecl. ObjCPropertyQueryKind currently has 3 values: OBJC_PR_query_unknown, OBJC_PR_query_instance, OBJC_PR_query_class This extra parameter specifies that we are looking for an instance property with the given name, or a class property with the given name, or any property with the given name (if both exist, the instance property will be returned). rdar://23891898 llvm-svn: 259070

| | | | | | | | | | | | | | | | | | Re-commit of r258950 after fixing layering violation. Add backend dignostic printer for unsupported features The related LLVM patch adds a backend diagnostic type for reporting unsupported features, this adds a printer for them to clang. In the case where debug location information is not available, I've changed the printer to report the location as the first line of the function, rather than the closing brace, as the latter does not give the user any information. This also affects optimisation remarks. Differential Revision: http://reviews.llvm.org/D16591 llvm-svn: 259036

* [Sema] Make extended vectors of `bool` an error.George Burgess IV2016-01-281-4/+10
| | | | | | | | | | | | | | In OpenCL, `bool` vectors are a reserved type, and are therefore illegal. Outside of OpenCL, if we try to make an extended vector of N `bool`s, Clang will lower it to an `[N x i1]`. LLVM has no ABI for bitvectors, so lots of operations on such vectors are thoroughly broken. As a result, this patch makes them illegal in everything else, as well. :) Differential Revision: http://reviews.llvm.org/D15721 llvm-svn: 259011

| | | | | | | | Various bits we'd like to use the new ABI actually compile with "-arch armv7k -miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how slices work. llvm-svn: 258976
* Emit calls to objc_unsafeClaimAutoreleasedReturnValue whenJohn McCall2016-01-275-171/+454
| | | | | | | | | | | | | | | | | reclaiming a call result in order to ignore it or assign it to an __unsafe_unretained variable. This avoids adding an unwanted retain/release pair when the return value is not actually returned autoreleased (e.g. when it is returned from a nonatomic getter or a typical collection accessor). This runtime function is only available on the latest Apple OS releases; the backwards-compatibility story is that you don't get the optimization unless your deployment target is recent enough.

* [analyzer] ObjCDeallocChecker: Only operate on classes with retained properties.Devin Coughlin2016-01-271-50/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the ObjC Dealloc Checker only checked classes with ivars, not retained properties, which caused three bugs: - False positive warnings about a missing -dealloc method in classes with only ivars. - Missing warnings about a missing -dealloc method on classes with only properties. - Missing warnings about an over-released or under-released ivar associated with a retained property in classes with only properties. The fix is to check only classes with at least one retained synthesized property. This also exposed a bug when reporting an over-released or under-released property that did not contain a synthesize statement. The checker tried to associate the warning with an @synthesize statement that did not exist, which caused an assertion failure in debug builds. The fix is to fall back to the @property statement in this case. A patch by David Kilzer! Part of rdar://problem/6927496 Differential Revision: http://reviews.llvm.org/D5023 llvm-svn: 258896
* Revert "Change of UserLabelPrefix default value from "_" to """James Y Knight2016-01-272-23/+32
| | | | | | | | | | | | | This reverts commit r258504. This commit breaks (at least) sparc-rtems -- the OS (RTEMS) used to override UserLabelPrefix to "", despite the arch (SPARC) having set it to "_". Now, the OS doesn't override anymore, but the arch sets it to "_", resulting in the wrong value. I expect this probably breaks other OSes that overrode to "" before, as well. (Clearly we have some missing test cases, here...) llvm-svn: 258894
* [analyzer] Body farm: Look for property ivar in shadowing readwrite property.Devin Coughlin2016-01-261-1/+40
| | | | | | | | | | | | After r251874, readonly properties that are shadowed by a readwrite property in a class extension no longer have an instance variable, which caused the body farm to not synthesize getters. Now, if a readonly property does not have an instance variable look for a shadowing property and try to get the instance variable from there. rdar://problem/24060091 llvm-svn: 258886
* [CUDA] Implemented device-side support functions in <cmath>.Artem Belevich2016-01-263-1/+228
| | | | | | | | | | | | | | | | CUDA expects math functions in std:: namespace to work on device side. In order to make it work with clang without allowing device-side code generation for functions w/o appropriate target attributes, this patch provides device-side implementations for <cmath> functions. Most of them call global-scope math functions provided by CUDA headers. In few cases we use clang builtins. Tested out-of tree by compiling and running thrust's unit_tests. https://github.com/thrust/thrust/tree/master/testing Differential Revision: http://reviews.llvm.org/D16593 llvm-svn: 258880
* [WinEH] Annotate calls to __RTtypeid with a funclet bundleDavid Majnemer2016-01-261-2/+5
| | | | | | | | | | Clang's CodeGen has several paths which end up invoking or calling a function. The one that we used for calls to __RTtypeid did not appropriately annotate the call with a funclet bundle. This fixes PR26329. llvm-svn: 258877

* [MS ABI] Allow a member pointers' converted type to changeDavid Majnemer2016-01-2610-5/+54
| | | | | | | | | | | | | | | | | | | | | | | | Member pointers in the MS ABI are tricky for a variety of reasons. The size of a member pointer is indeterminate until the program reaches a point where the representation is required to be known. However, *pointers* to member pointers may exist without knowing the pointee type's representation. In these cases, we synthesize an opaque LLVM type for the pointee type. However, we can be in a situation where the underlying member pointer's representation became known mid-way through the program. To account for this, we attempted to manicure CodeGen's type-cache so that we can replace the opaque member pointer type with the real deal while leaving the pointer types unperturbed. This, unfortunately, is a problematic approach to take as we will violate CodeGen's invariants. These violations are mostly harmless but let's do the right thing instead: invalidate the type-cache if a member pointer's LLVM representation changes. This fixes PR26313. llvm-svn: 258839

When -fcuda-allow-variadic-functions is passed, the front-end makes no attempt to disallow C-style variadic functions. Calls to va_arg are still not allowed.
