* [OPENMP] Set '_OPENMP' macro to '201511' value to reflect support forAlexey Bataev2016-05-261-1/+1
| | | | | | | | OpenMP 4.5. According to OpenMP 4.5 the _OPENMP macro name is defined to have the decimal value yyyymm where yyyy and mm are the year and month designations of the version of the OpenMP API that the implementation supports. Clang supports OpenMP 4.5 so updated value of _OPENMP macro to 201511. llvm-svn: 270822
* [Driver] Add support for -finline-functions and /Ob2 flagsHans Wennborg2016-05-241-2/+6
| | | | | | | | | | | | | | | | | | -finline-functions and /Ob2 are currently ignored by Clang. The only way to enable inlining is to use the global O flags, which also enable other options, or to emit LLVM bitcode using Clang, then running opt by hand with the inline pass. This patch allows to simply use the -finline-functions flag (same as GCC) or /Ob2 in clang-cl mode to enable inlining without other optimizations. This is the first patch of a serie to improve support for the /Ob flags. Patch by Rudy Pons <rudy.pons@ilod.org>! Differential Revision: http://reviews.llvm.org/D20576 llvm-svn: 270609

* [PCH] Fixed bug with preamble invalidation when overridden files changeCameron Desrochers2016-05-171-13/+23
| | | | | | | | When remapped files were changed, they would not always cause the preamble's PCH to be invalidated, because the remapped path didn't necessarily match the include path (e.g. slash direction -- this happens a lot on Windows). I fixed this by moving to a llvm::sys::fs::UniqueID-based map instead of comparing paths stringwise. Differential Revision: http://reviews.llvm.org/D20137 llvm-svn: 269769

* [Modules] Use vfs for (recursive) directory iterationBruno Cardoso Lopes2016-05-161-6/+7
| | | | | | | | | | | | | | | | Clang performs directory walk while searching headers inside modules by using the ::sys::fs instead of ::vfs. This prevents any code that uses the VFS (e.g, reproducer scripts) to actually find such headers, since the VFS will never be searched for those. Change these places to use vfs::recursive_directory_iterator and vfs::directory_iterator instead. Differential Revision: http://reviews.llvm.org/D20266 rdar://problem/25880368 llvm-svn: 269661

* [ModuleMap][CrashReproducer] Collect headers from inner frameworksBruno Cardoso Lopes2016-05-131-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (1) Collect headers under inner frameworks (frameworks inside other other frameworks). (2) Make sure we also collect the right header files inside them. More info on (2): Consider a dummy framework module B, with header Frameworks/B/B.h. Now consider that another framework A, with header Frameworks/A/A.h, has a layout with a inner framework Frameworks/A/Frameworks/B/B.h, where the "B/B.h" part is a symlink for Frameworks/B/B.h. Also assume that Frameworks/A/A.h includes <B/B.h>. When parsing header Frameworks/A/A.h, framework module lookup is performed in search for B, and it happens that "Frameworks/A/Frameworks/B/B.h" path is registered in the module instead of real "Frameworks/B/B.h". This occurs because "Frameworks/A/Frameworks/B/B.h" is scanned first by the FileManager, when looking for inner framework modules under Frameworks/A/Frameworks. This makes Frameworks/A/Frameworks/B/B.h the default cached named inside the FileManager for the B.h file UID. This leads to modules being built without consistent paths to underlying header files. This is usually not a problem in regular compilation flow, but it's an issue when running the crash reproducer. The issue is that clangs collect "Frameworks/A/Frameworks/B/B.h" but not "Frameworks/B/B.h" into the VFS, leading to err_mmap_umbrella_clash. So make sure we also collect the original header.

* Embed bitcode in object file (clang cc1 part)Steven Wu2016-05-111-0/+39
| | | | | | | | | | | | | | | | | | | Summary: Teach clang to embed bitcode inside bitcode. When -fembed-bitcode cc1 option is used, clang will embed both the input bitcode and cc1 commandline into the bitcode in special sections before compiling to the object file. Using -fembed-bitcode-marker will only introduce a marker in both sections.

* [CrashReproducer] Always use realpath for destinationBruno Cardoso Lopes2016-05-061-20/+13
| | | | | | | | | | When running reproducer scripts we need that original symlinks from the source filesystem are reproduced in the VFS so that different virtual paths can map to the same file, allowing the FileManager to share the same UID between these virtual entries. This avoids all sorts of module redefinition errors when using frameworks. llvm-svn: 268825

* Frontend: support -I=path for sysroot expansionSaleem Abdulrasool2016-05-061-2/+14
| | | | | | | | | | | | | | | | | | From the GCC manpage: -I dir ... If dir begins with =, then the = will be replaced by the sysroot prefix; see --sysroot and -isysroot. Add support to expand the `=` as a prefix of the include path with the sysroot if specified. `-isysroot` takes precedence over `--sysroot` as the normal argument behaviour occurs. The ordering of the `-isysroot` is relevant to the path substituted. If no `--sysroot=` or `-isysroot` option is present, the = is not expanded. Resolves PR26965! llvm-svn: 268777

* 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

* Move EABIVersion from CodeGenOptions to TargetOptionsSaleem Abdulrasool2016-04-081-16/+17
| | | | | | | | | 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

* Replace Sema-level implementation of -fassume-sane-operator-new with aRichard Smith2016-04-071-1/+1
| | | | | | | | | | | | | | 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
| | | | | | | | This is a mechanical move of CodeGenOptions from libFrontend to libBasic. This fixes the layering violation introduced earlier by threading CodeGenOptions into TargetInfo. It should also fix the modules based self-hosting builds. NFC. llvm-svn: 265702
