* Reapply [VFS] Add 'overlay-relative' field to YAML filesBruno Cardoso Lopes2016-03-173-20/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reapplies r261552. 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" }, ... Here, a file manager request for virtual "/usr/include/stdio.h", that will map into real path "/<absolute_path_to>/<name>.cache/vfs/usr/include/stdio.h. This is a useful feature for debugging module crashes in machines other than the one where the error happened.

* Reapply [2]: [VFS] Add support for handling path traversalsBruno Cardoso Lopes2016-03-172-24/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix destructor definition of invalid classesOlivier Goffart2016-03-161-8/+10
| | | | | | | | | | | | The declaration of the destructor of an invalid class was not properly marked as noexcept.

* Convert some ObjC msgSends to runtime calls.Pete Cooper2016-03-165-18/+121
| | | | | | | | | | | | | | It is faster to directly call the ObjC runtime for methods such as retain/release instead of sending a message to those functions. This patch adds support for converting messages to retain/release/alloc/autorelease to their equivalent runtime calls. Tests included for the positive case of applying this transformation, negative tests that we ensure we only convert "alloc" to objc_alloc, not "alloc2", and also a driver test to ensure we enable this only for supported runtime versions.

* [cfi] Don't emit checks for disabled CFI kinds.Evgeniy Stepanov2016-03-151-8/+7
| | | | | | | | | | | | | | In the cross-DSO CFI mode clang emits __cfi_check_fail that handles errors triggered from other modules with targets in the current module. With this change, __cfi_check_fail will handle errors for CFI kinds that are not enabled in the current module as if they have the trapping behaviour (-fsanitize-trap=...). This fixes a bug where some combinations of -fsanitize* flags may result in a link failure due to a missing sanitizer runtime library for the diagnostic calls in __cfi_check_fail. llvm-svn: 263578

* CodeGen: Use 32-bit gep offsets to address vtable address points.Peter Collingbourne2016-03-142-5/+5
| | | | | | | | | | | | | | | | | The relative vtable ABI will use a struct rather than an array as the type of a vtable. LLVM only allows 32-bit integers as struct indices, so we need to use 32-bit integers to get addresses of address points. In order to keep the code simple, we might as well do that unconditionally. It's probably a reasonable implementation limit to support no more than 2 billion virtual functions per class. This change causes quite a bit of churn in the test suite, so I'm making it separately.
