* [CUDA] Copy host builtin types to NVPTXTargetInfo.Justin Lebar2016-04-292-1/+8
| | | | | | | | | | | | | | | | | Summary: Host and device types must match, otherwise when we pass values back and forth between the host and device, we will get the wrong result. This patch makes NVPTXTargetInfo inherit most of its type information from the host's target info.

* Rework interface for bitset-using features to use a notion of LTO visibility.Peter Collingbourne2016-04-271-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bitsets, and the compiler features they rely on (vtable opt, CFI), only have visibility within the LTO'd part of the linkage unit. Therefore, only enable these features for classes with hidden LTO visibility. This notion is based on object file visibility or (on Windows) dllimport/dllexport attributes. We provide the [[clang::lto_visibility_public]] attribute to override the compiler's LTO visibility inference in cases where the class is defined in the non-LTO'd part of the linkage unit, or where the ABI supports calling classes derived from abstract base classes with hidden visibility in other linkage units (e.g. COM on Windows). If the cross-DSO CFI mode is enabled, bitset checks are emitted even for classes with public LTO visibility, as that mode uses a separate mechanism to cause bitsets to be exported. This mechanism replaces the whole-program-vtables blacklist, so remove the -fwhole-program-vtables-blacklist flag. Because __declspec(uuid()) now implies [[clang::lto_visibility_public]], the support for the special attr:uuid blacklist entry is removed.

* [CrashReproducer] Setup 'use-external-names' in YAML files.Bruno Cardoso Lopes2016-04-131-0/+4
| | | | | | | | | | | | | | Hide the real paths when rebuilding from VFS by setting up the crash reproducer to use 'use-external-names' = false. This way we avoid module redifinition errors and consistently use the same paths against all modules. With this change on Darwin we are able to simulate a crash for a simple application using "Foundation/Foundation.h" (which relies on a bunch of different frameworks and headers) and successfully rebuild all the modules by relying solely at the VFS overlay. llvm-svn: 266234

| | | | | | | | | It is possible to argue that the EABIVersion field is similar in spirit to the ABI field in TargetOptions. It represents the embedded ABI that the target follows. This will allow us to thread this information into the target information construction. llvm-svn: 265807

| | | | | | | | | | | | | | CodeGen-level implementation. Instead of adding an attribute to clang's FunctionDecl, add the IR attribute directly. This means a module built with this flag is now compatible with code built without it and vice versa. This change also results in the 'noalias' attribute no longer being added to calls to operator new in the IR; it's now only added to the declaration. It also fixes a bug where we failed to add the attribute to the 'nothrow' versions (because we didn't implicitly declare them, there was no good time to inject a fake attribute). llvm-svn: 265728
* Basic: move CodeGenOptions from FrontendSaleem Abdulrasool2016-04-072-33/+0

* [OPENMP] Parsing and Sema support for 'omp declare target' directiveDmitry Polukhin2016-04-061-0/+6
| | | | | | | | | | | | | | | | | | | | 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.

* [CrashReproducer] Add a module map callback for added headersBruno Cardoso Lopes2016-03-301-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ModuleDependencyCollector has a AST listener to collect header files present in loaded modules, but this isn't enough to collect all headers needed in the crash reproducer. One of the reasons is that the AST writer doesn't write symbolic link header paths in the pcm modules, this makes the listeners on the reader only able to collect the real files. Since the module maps could contain submodules that use headers which are symbolic links, not collecting those forbid the reproducer scripts to regen the modules. For instance: usr/include/module.map: ... module pthread { header "pthread.h" export * module impl { header "pthread_impl.h" export * } } ... usr/include/pthread/pthread_impl.h usr/include/pthread_impl.h -> pthread/pthread_impl.h The AST dump for the module above: <SUBMODULE_HEADER abbrevid=6/> blob data = 'pthread_impl.h' <SUBMODULE_TOPHEADER abbrevid=7/> blob data = '/<path_to_sdk>/usr/include/pthread/pthread_impl.h' Note that we don't have "usr/include/pthread_impl.h" which is requested by the module.map in case we want to reconstruct the module in the reproducer. The reason the original symbolic link path isn't used is because the headers are kept by name and requested through the FileManager, which unique files and returns the real path only. To fix that, add a callback to be invoked everytime a header is added while parsing module maps and hook that up to the module dependecy collector. This callback is only registered when generating the reproducer. Differential Revision: http://reviews.llvm.org/D18585 rdar://problem/24499339 llvm-svn: 264971
* [CUDA] Make unattributed constexpr functions implicitly host+device.Justin Lebar2016-03-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | With this patch, by a constexpr function is implicitly host+device unless: a) it's a variadic function (variadic functions are not allowed on the device side), or b) it's preceeded by a __device__ overload in a system header. The restriction on overloading __host__ __device__ functions on the basis of their CUDA attributes remains in place, but we use (b) to allow us to define __device__ overloads for constexpr functions in cmath, which would otherwise be __host__ __device__ and thus not overloadable. You can disable this behavior with -fno-cuda-host-device-constexpr. Reviewers: tra, rnk, rsmith Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D18380 llvm-svn: 264964

The original version had erroneously emitted functions that are defined in class templates, too (see the updated "Handle friend functions" code in EmitDeferredDecls, lib/CodeGen/ModuleBuilder.cpp). (The updated tests needed to be split out into their own dllexport-ms-friend.cpp because of the CHECK-NOTs which would have interfered with subsequent CHECK-DAGs in dllexport.cpp.) Differential Revision: http://reviews.llvm.org/D18430 llvm-svn: 264841

* clang-cl: Include /FI headers in /showIncludes output.Nico Weber2016-03-233-9/+16
| | | | | | | | | | | | | | | | | -H in gcc mode doesn't print -include headers, but they are included in depfiles written by MMD and friends. Since /showIncludes is what's used instead of depfiles, printing /FI there seems important (and matches cl.exe). Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders in clang-cl mode and let clang::InitializePreprocessor() not put -include flags in the <command line> block. This changes the behavior of -E slightly, and it removes the <command line> flag from the output triggered by setting the obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these seem ok to change. http://reviews.llvm.org/D18401 llvm-svn: 264174

* Reapply [2] [VFS] Add 'overlay-relative' field to YAML filesBruno Cardoso Lopes2016-03-202-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reapplies r261552 and r263748. Fixed testcase to reapply. The VFS overlay mapping between virtual paths and real paths is done through the 'external-contents' entries in YAML files, which contains hardcoded paths to the real files. When a module compilation crashes, headers are dumped into <name>.cache/vfs directory and are mapped via the <name>.cache/vfs/vfs.yaml. The script generated for reproduction uses -ivfsoverlay pointing to file to gather the mapping between virtual paths and files inside <name>.cache/vfs. Currently, we are only capable of reproducing such crashes in the same machine as they happen, because of the hardcoded paths in 'external-contents'. To be able to reproduce a crash in another machine, this patch introduces a new option in the VFS yaml file called 'overlay-relative'. When it's equal to 'true' it means that the provided path to the YAML file through the -ivfsoverlay option should also be used to prefix the final path for every 'external-contents'. Example, given the invocation snippet "... -ivfsoverlay <name>.cache/vfs/vfs.yaml" and the following entry in the yaml file: "overlay-relative": "true", "roots": [ ... "type": "directory", "name": "/usr/include", "contents": [ { "type": "file", "name": "stdio.h", "external-contents": "/usr/include/stdio.h" }, ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was applied twice r261551 and 263617 and later reverted because: (1) Windows bot failing on unittests. Change the current behavior to do not handle path traversals on windows. (2) Windows bot failed to include llvm/Config/config.h in order to use HAVE_REALPATH. Use LLVM_ON_UNIX instead, as done in lib/Basic/FileManager.cpp. Handle ".", ".." and "./" with trailing slashes while collecting files to be dumped into the vfs overlay directory. Include the support for symlinks into components. Given the path: /install-dir/bin/../lib/clang/3.8.0/include/altivec.h, if "bin" component is a symlink, it's not safe to use `path::remove_dots` here, and `realpath` is used to get the right answer. Since `realpath` is expensive, we only do it at collecting time (which only happens during the crash reproducer) and cache the base directory for fast lookups. Overall, this makes the input to the VFS YAML file to be canonicalized to never contain traversal components.
