* Validate user headers even if -fmodules-validate-once-per-build-sessionBen Langmuir2014-11-101-3/+2

* AArch64: set all processor features from -arch if nothing else presentTim Northover2014-11-101-0/+6
| | | | | | | | | | Darwin's "-arch arm64" option implies full Cyclone CPU, for both architectural and tuning purposes. So if neither of the explicit options have been given, forward that on to the proper invocation. rdar://problem/18906227 llvm-svn: 221631

* clang-format: [Java] Never treat @interface as annotation.Nico Weber2014-11-102-1/+5
| | | | | | | | | '@' followed by any keyword can't be an annotation, but @interface is currently the only combination of '@' and a keyword that's allowed, so limit it to this case. `@interface Foo` without a leading `public` was misformatted prior to this patch. llvm-svn: 221607
* [Tooling] Restore current directory after processing each file.Alexander Kornienko2014-11-101-2/+17

* [c++1z] Implement nested-namespace-definitions.Richard Smith2014-11-081-19/+18
| | | | | | | | | | | | | This allows 'namespace A::B { ... }' as a shorthand for 'namespace A { namespace B { ... } }'. We already supported this correctly for error recovery; promote that support to a full implementation. This is not the right implementation: we do not maintain source fidelity because we desugar the nested namespace definition in the parser. This is tricky to avoid, since the definition genuinely does inject one named entity per level in the namespace name. llvm-svn: 221574
* [c++1z] N4295: fold-expressions.Richard Smith2014-11-0814-7/+405
| | | | | | | | | | | | | | | | This is a new form of expression of the form: (expr op ... op expr) where one of the exprs is a parameter pack. It expands into (expr1 op (expr2onwards op ... op expr)) (and likewise if the pack is on the right). The non-pack operand can be omitted; in that case, an empty pack gives a fallback value or an error, depending on the operator. llvm-svn: 221573

* ARM ABI: simplify decisions on whether args can be expanded.Tim Northover2014-11-071-35/+21
| | | | | | | | | | | | Homogeneous aggregates on AAPCS_VFP ARM need to be passed *without* being flattened (e.g. [2 x float] rather than "float, float") for various weird ABI reasons. However, this isn't the case for anything else; further, we know at the ABIArgInfo::getDirect callsites whether this flattening is allowed. So, we can get more unified ARM code, with a simpler Clang, by just using that knowledge directly. llvm-svn: 221559
* Introduce a SanitizerKind enum to LangOptions.Alexey Samsonov2014-11-0718-237/+241
| | | | | | | | | | | | | Use the bitmask to store the set of enabled sanitizers instead of a bitfield. On the negative side, it makes syntax for querying the set of enabled sanitizers a bit more clunky. On the positive side, we will be able to use SanitizerKind to eventually implement the new semantics for -fsanitize-recover= flag, that would allow us to make some sanitizers recoverable, and some non-recoverable. No functionality change. llvm-svn: 221558

* Fix clash of gcc toolchains in hexagon driver regression tests.Samuel Antao2014-11-073-10/+15
| | | | | | If clang was configured with a custom gcc toolchain (either by using GCC_INSTALL_PREFIX in cmake or the equivalent configure command), the path to the custom gcc toolchain path takes precedence to the one specified by -ccc-install-dir. This causes several regression tests to fail as they will be using an unexpected path. Adding the switch --gcc-toolchain="" in each test command is not enough as the hexagon toolchain implementation in the driver is not evaluating this argument. This commit modifies the hexagon toolchain to take the --gcc-toolchain="" argument into account when deciding the toolchain path, similarly to what is already done for other targets toolchains. Additionally, the faulty regression tests are modified in order to --gcc-toolchain="" be passed to the commands. llvm-svn: 221535

* [X86] Slightly refactor default features for AMD bdver cpus (NFC). Also add ↵Andrea Di Biagio2014-11-061-12/+7
| | | | | | | | | | | | | | | | | | | missing checks to test for target features. This patch simplifies how default target features are set for AMD bdver2 and bdver1. In particular, method 'getDefaultFeatures' now implements a fallthrough from case 'CK_BDVER2' to case 'CK_BDVER1'. That is because 'bdver2' has the same features available in bdver1 plus BMI, FMA, F16C and TBM. This patch also adds missing checks for predefined macros in test predefined-arch-macros.c. In the case of BTVER2, the test now also checks for F16C, BMI and PCLMUL. In the case of BDVER3 and BDVER4, the test now also checks for the presence of FSGSBASE.

However, FunctionDecl as rebuilt in RebuildUnknownAnyExpr::resolveDecl is bogus and results in crash when accessing its params later on.

* [DebugInfo] Do not record artificial global initializer functions in the ↵Frederic Riss2014-11-051-1/+4

When we are generating the global initializer functions, we call CGDebugInfo::EmitFunctionStart() with a valid decl which is describing the initialized global variable. Do not update the DeclCache with this key as it will overwrite the the cached variable DIGlobalVariable with the newly created artificial DISubprogram. One could wonder if we should put artificial subprograms in the DIE tree at all (there are vaild uses for them carrying line information though). llvm-svn: 221385

* Use @rpath as LC_ID_DYLIB for ASan dylib on OS XKuba Brecka2014-11-042-7/+30
| | | | | | | | Change the LC_ID_DYLIB of ASan's dynamic libraries on OS X to be set to "@rpath/libclang_rt.asan_osx_dynamic.dylib" and similarly for iossim. Clang driver then sets the "-rpath" to be the real path to where clang currently has the dylib (because clang uses the relative path to its current executable). This means if you move the compiler or install the binary release, -fsanitize=address will link to the proper library. Reviewed at http://reviews.llvm.org/D6018 llvm-svn: 221279
