* Enable PIE for CloudABI.Ed Schouten2016-04-062-1/+7
| | | | | | | | | | | | | | | | | | As we're currently working on making CloudABI executables easier to emulate in userspace (e.g., on OS X and Windows), it makes a whole lot of sense to build these using PIE. By using PIE, they can simply be loaded into the existing process address space without clashes. PIE support got added to CloudABI's C library and seems to work pretty well. CloudABI does not make use of an ld.so, so the binary's _start() has all the logic in it to do the relocations. Now that all but one bug in LLD relating to PIE support have been squashed (and a patch for that is already in code review), I'd like to go ahead and force the use of PIE for Clang 3.9. When released, we'll also switch over to using LLD exclusively. llvm-svn: 265546

* [OPENMP] Parsing and Sema support for 'omp declare target' directiveDmitry Polukhin2016-04-0612-2/+248
| | | | | | | | | | | | | | | | | | | | Add parsing, sema analysis for 'declare target' construct for OpenMP 4.0 (4.5 support will be added in separate patch). The declare target directive specifies that variables, functions (C, C++ and Fortran), and subroutines (Fortran) are mapped to a device. The declare target directive is a declarative directive. In Clang declare target is implemented as implicit attribute for the declaration. The syntax of the declare target directive is as follows: #pragma omp declare target declarations-definition-seq #pragma omp end declare target Based on patch from Michael Wong http://reviews.llvm.org/D15321 llvm-svn: 265530

| | | | | | | | This is a fix for https://llvm.org/bugs/show_bug.cgi?id=25561 which was a crash on invalid. Change the handling of invalid decls to have a catch-all case to prevent unexpecting decls from triggering an assertion. llvm-svn: 265467
* [CUDA] Add -fcuda-flush-denormals-to-zero.Justin Lebar2016-04-054-0/+19
| | | | | | | | | | | | | | | | | | Summary: Setting this flag causes all functions are annotated with the "nvvm-f32ftz" = "true" attribute. In addition, we annotate the module with "nvvm-reflect-ftz" set to 0 or 1, depending on whether -cuda-flush-denormals-to-zero is set. This is read by the NVVMReflect pass.

* [OPENMP] Codegen for teams directive for NVPTXCarlo Bertolli2016-04-045-21/+104
| | | | | | | | | | | | This patch implements the teams directive for the NVPTX backend. It is different from the host code generation path as it: Does not call kmpc_fork_teams. All necessary teams and threads are started upon touching the target region, when launching a CUDA kernel, and their execution is coordinated through sequential and parallel regions within the target region. Does not call kmpc_push_num_teams even if a num_teams of thread_limit clause is present. Setting the number of teams and the thread limit is implemented by the nvptx-related runtime. Please note that I am now passing a Clang Expr * to emitPushNumTeams instead of the originally chosen llvm::Value * type. The reason for that is that I want to avoid emitting expressions for num_teams and thread_limit if they are not needed in the target region. http://reviews.llvm.org/D17963 llvm-svn: 265304

* [Objective-C] Introduce objc_runtime_visible attribute.Douglas Gregor2016-04-013-0/+69
| | | | | | | | | | | | | | | | | | | | The objc_runtime_visible attribute deals with an odd corner case where a particular Objective-C class is known to the Objective-C runtime (and, therefore, accessible by name) but its symbol has been hidden for some reason. For such classes, teach CodeGen to use objc_lookUpClass to retrieve the Class object, rather than referencing the class symbol directly. Classes annotated with objc_runtime_visible have two major limitations that fall out from places where Objective-C metadata needs to refer to the class (or metaclass) symbol directly: * One cannot implement a subclass of an objc_runtime_visible class. * One cannot implement a category on an objc_runtime_visible class. Implements rdar://problem/25494092. llvm-svn: 265201
* [CodeGen] Emit lifetime.end intrinsic after objects are destructed inAkira Hatanaka2016-04-013-4/+16

This prevented StackColoring from merging stack slots for objects that were destroyed on the exception handling control flow since it couldn't tell their lifetime ranges were disjoint. This patch fixes code-gen to emit the intrinsic on both control flows. rdar://problem/22181976 Differential Revision: http://reviews.llvm.org/D18196 llvm-svn: 265197

* [analyzer] Prefer accessor method in extension over category in CallEvent.Devin Coughlin2016-04-011-2/+24
| | | | | | | | | | | | | | In ObjCMethodCall:getRuntimeDefinition(), if the method is an accessor in a category, and it doesn't have a self declaration, first try to find the method in a class extension. This works around a bug in Sema where multiple accessors are synthesized for properties in class extensions that are redeclared in a category. The implicit parameters are not filled in for the method on the category, which causes a crash when trying to synthesize a getter for the property in BodyFarm. The Sema bug is tracked as rdar://problem/25481164. rdar://problem/25056531 llvm-svn: 265103

* [CodeGenCXX] Fix ItaniumCXXABI::getAlignmentOfExnObject to return 8-byteAkira Hatanaka2016-03-312-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alignment on Darwin. Itanium C++ ABI specifies that _Unwind_Exception should be double-word aligned (16B). To conform to the ABI, libraries implementing exception handling declare the struct with __attribute__((aligned)), which aligns the unwindHeader field (and the end of __cxa_exception) to the default target alignment (which is typically 16-bytes). struct __cxa_exception { ... // struct is declared with __attribute__((aligned)). _Unwind_Exception unwindHeader; }; Based on the assumption that _Unwind_Exception is declared with __attribute__((aligned)), ItaniumCXXABI::getAlignmentOfExnObject returns the target default alignment for __attribute__((aligned)). It turns out that libc++abi, which is used on Darwin, doesn't declare the struct with the attribute and therefore doesn't guarantee that unwindHeader is aligned to the alignment specified by the ABI, which in some cases causes the program to crash because of unaligned memory accesses. This commit avoids crashes due to unaligned memory accesses by having getAlignmentOfExnObject return an 8-byte alignment on Darwin. I've only fixed the problem for Darwin, but we should also figure out whether other platforms using libc++abi need similar fixes. rdar://problem/25314277 Differential revision: http://reviews.llvm.org/D18479 llvm-svn: 264998
