* Create a redeclaration when an elaborated type specifierJohn McCall2014-05-141-3/+6
| | | | | | | | | resolves to an existing declaration if there are attributes present. This gives us something to apply the attributes to. llvm-svn: 208756
* DebugInfo: Avoid creating DILexicalScopeFiles when the filename in the ↵David Blaikie2014-05-141-7/+11
| | | | | | | | | | | | | | | | | | | current scope has not changed. This looks like the right way for this check to work, but there is another semi-obvious bug, I would think: why is CurLoc not zero'd out between functions? The possibility for it to bleed between them seems problematic. (& indeed I caused tests to fail when I fixed this a different way, by setting CurLoc to SourceLocation() and the end of EmitFunctionEnd... ) The changes to debug-info-blocks.m are due to a mismatch between the source manager's file naming and CGDebugInfo's default handling when no -main-file-name is specified. This actually reveals somewhat of a bug in the debug info when using source files from standard in, too. See the comment in CGDebugInfo::CreateCompileUnit for more details. llvm-svn: 208742
* Push record return type classification into CGCXXABIReid Kleckner2014-05-134-113/+84
| | | | | | | | | | | | In the Microsoft C++ ABI, instance methods always return records indirectly via the second hidden parameter. This was implemented in X86_32ABIInfo, but not WinX86_64ABIInfo. Rather than exposing a handful of boolean methods in the CGCXXABI interface, we can expose a single method that applies C++ ABI return value classification rules. llvm-svn: 208733
* PR19729: Delete a bunch of bogus code in Sema::FindAllocationOverload. ThisRichard Smith2014-05-132-48/+28
| | | | | | | | | caused us to perform copy-initialization for the parameters of an allocation function called by a new-expression multiple times, resulting in us rejecting allocations that passed non-copyable parameters (and much worse things in MSVC compat mode, where we potentially called this function multiple times). llvm-svn: 208724

* Support -masm= flag for x86 targets.Nico Weber2014-05-131-0/+11
| | | | | | | `clang -S -o - file.c -masm=att` will write assembly to stdout in at&t syntax (the default), `-masm=intel` will instead output intel style asm. llvm-svn: 208683

* MS ABI: Tighten RTTI manglingDavid Majnemer2014-05-131-21/+21
| | | | | | r208661 contained WIP code, commit the *actual* manglings. llvm-svn: 208668
* Patched clang to emit x86 blends as shufflevectors.Filipe Cabecinhas2014-05-133-8/+62
| | | | | | | | | | | | | | | | | Summary: Most of the clang header patch by Simon Pilgrim @ SCEE. Also fixed (or added) clang tests for these intrinsics. LLVM tests to make sure we get the blend instruction out of these shufflevectors are at http://reviews.llvm.org/D3600 Reviewers: eli.friedman, craig.topper, rafael Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D3601 llvm-svn: 208664
* Refactor to avoid explicitly listing all the different flavours of redeclarableRichard Smith2014-05-131-56/+43

* MS ABI: Preliminary RTTI manglingDavid Majnemer2014-05-131-14/+69
| | | | | | | | Implement what we currently believe is the mangling scheme for RTTI data. Tests will be added in a later commit which actually generate RTTI data. llvm-svn: 208661
* Refactor and fix a latent bug (found by inspection) where an external ASTRichard Smith2014-05-131-21/+18
| | | | | | | | | source that provides a declaration from a hidden module would not have the visibility of the produced definition checked. This might matter if an external source chose to import a new module to provide an extra definition, but is not observable with our current external sources. llvm-svn: 208659
* [ASan] Fixup for r208610: link in asan_cxx library on WindowsAlexey Samsonov2014-05-121-6/+14

* [ASan] Split static ASan runtime in two parts: asan and asan_cxx.Alexey Samsonov2014-05-121-6/+11
| | | | | | | | | | | asan_cxx containts replacements for new/delete operators, and should only be linked in C++ mode. We plan to start building this part with exception support to make new more standard-compliant. See https://code.google.com/p/address-sanitizer/issues/detail?id=295 for more details. llvm-svn: 208610
* clang-format: [JS] Basic support for escape sequences in regex literals.Daniel Jasper2014-05-121-1/+21
| | | | | | | | | | Before: var regex = /\\/ g; // This isn't even recognized as regex. After: var regex = /\\/g; // It now is. llvm-svn: 208539
* [Driver] Do not lose already detected set of toolchain's multilibs whileSimon Atanasyan2014-05-122-33/+41
| | | | | | | | | | | | | | | | | iterating over different library path suffixes and different library versions. To find the most appropriate library for the given command line flags we iterate over a set of disk paths. Before probe each path the already detected set of multilibs are cleared. If the set of paths contains existing paths which do not satisfy command line flags or do not contain necessary libraries and object files at all we might lose found multilibs. The patch updates variables which hold detected multilibs if we really find a new multilib matches command line flags. The patch reviewed by Jon Roelofs. llvm-svn: 208523

* Driver: Don't leak the -Xarch argument when its use is incorrect.Nico Weber2014-05-111-2/+2
| | | | | | | (LLVM's lib/Option looks like it might appreciate being hit with the std::unique_ptr stick.) llvm-svn: 208505

* Add FIXME describing the limitation of using column info to disambiguate ↵David Blaikie2014-05-101-0/+8
| | | | | | | | | | | | | | | | | | | | inlining. Also tidy up, simplify, and extend the test coverage to demonstrate the limitations. This test should now fail if the bugs are fixed (& hopefully whoever ends up in this situation sees the FIXMEs and realizes that the test needs to be updated to positively test their change that has fixed some or all of these issues). I do wonder whether I could demonstrate breakage without a macro here, but any way I slice it I can't think of a way to get two calls to the same function on the same line/column in non-macro C++ - implicit conversions happen at the same location as an explicit function, but you'd never get an implicit conversion on the result of an explicit call to the same implicit conversion operator (since the value is already converted to the desired result)... llvm-svn: 208468

* MS ABI: Pass 'sret' as the second parameter of instance methodsReid Kleckner2014-05-095-20/+76
| | | | | | | | | | | | | | | | | Summary: MSVC always passes 'sret' after 'this', unlike GCC. This required changing a number of places in Clang that assumed the sret parameter was always first in LLVM IR. This fixes win64 MSVC ABI compatibility for methods returning structs. Reviewers: rsmith, majnemer Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D3618 llvm-svn: 208458
* Don't emit -Wnon-virtual-dtor on final classes, since it's not a problem there.David Blaikie2014-05-091-1/+2
| | | | | | | | | The base class is the culprit/risk here - a sealed/final derived class with virtual functions and a non-virtual dtor can't accidentally be polymorphically destroyed (if the base class's dtor is protected - which also suppresses this warning). llvm-svn: 208449
* PR19698, PR19674: enable __has_feature checks for cxx_generic_lambdas andRichard Smith2014-05-091-3/+8

* Add the ability to use logical expressions for capability attributes. This ↵Aaron Ballman2014-05-093-1/+161
| | | | | | | | | | is to allow requirements to be expressed not just in terms of lists, but in terms of logical expressions. Eg) void foo(void) __attribute__((requires_capability((FlightControl || Worker) && !Logger))); This is WIP code. llvm-svn: 208439
* Don't leak MacroArgs when using code completion, PR19688.Nico Weber2014-05-091-1/+4
| | | | | | | | | | | | | | | | | | | | | | | MacroArgs are owned by TokenLexer, and when a TokenLexer is destroyed, it'll call its MacroArgs's destroy() method. destroy() only appends the MacroArg to Preprocessor's MacroArgCache list, and Preprocessor's destructor then calls deallocate() on all MacroArgs in that list. This method then ends up freeing the MacroArgs's memory. In a code completion context, Parser::cutOffParsing() gets called when a code completion token is hit, which changes the type of the current token to tok::eof. eof tokens aren't always ConsumeToken()ed, so Preprocessor::HandleEndOfFile() isn't always called, and that function is responsible for popping the macro stack. Due to this, Preprocessor::CurTokenLexer can be non-NULL when ~Preprocessor runs. It's a unique_ptr, so it ended up being destructed after ~Preprocessor completed, and its MacroArgs thus got added to the freelist after the code freeing things on the freelist had already completed. The fix is to explicitly call reset() before the freelist processing happens. (See the bug for more notes.) llvm-svn: 208438
* ThreadSafetyAnalysis: Don't crash when trying to analyze objc methods.Benjamin Kramer2014-05-091-4/+6
| | | | | | | | | | | The thread safety analysis isn't very useful in ObjC (you can't annotate ObjC classes or methods) but we can still analyze the actual code and show violations in usage of C/C++ functions. Fixes PR19541, which does not use thread safety attributes but crashes with -Weverything. llvm-svn: 208436
