* PR19352 - getLocation() points to the wrong position for FriendDeclsNikola Smiljanic2014-05-231-1/+3
| | | | llvm-svn: 209511
* Implemented support for "pragma clang optimize on/off", based on attribute ↵Dario Domizioli2014-05-235-0/+110
| | | | | | | | | | | | | | | | 'optnone'. This patch implements support for selectively disabling optimizations on a range of function definitions through a pragma. The implementation is that all function definitions in the range are decorated with attribute 'optnone'. #pragma clang optimize off // All function definitions in here are decorated with 'optnone'. #pragma clang optimize on // Compilation resumes as normal. llvm-svn: 209510
* Fix '-main-file-name <name>' so that it is used for the ModuleID.Robert Lytton2014-05-231-1/+4
| | | | | | | | | Summary: Previously, you could not specify the original file name when passing a preprocessed file into the compiler Now you can use 'clang -Xclang -main-file-name -Xclang <original file name> ...' Or 'clang -cc1 -main-file-name <original file name> ...' llvm-svn: 209503
* Fix a bug in xmmintrin.h.Akira Hatanaka2014-05-231-1/+1
| | | | | | | | | | The last step of _mm_cvtps_pi16 should use _mm_packs_pi32, which is a function that reads two __m64 values and packs four 32-bit values into four 16-bit values. <rdar://problem/16873717> llvm-svn: 209489
* Don't set unnamed_addr in CreateRuntimeVariable.Rafael Espindola2014-05-222-9/+3
| | | | | | | | | | | | | This was fairly broken. For example, @__dso_handle would or would not get an unnamed_addr depending on how many global destructors were used in a translation unit. The consensus was that not every runtime variable is unnamed_addr and that __dso_handle handle should not be, so just don't add unnamed_addr in CreateRuntimeVariable. llvm-svn: 209484
* Avoid allocating extra memory to handle the lazy definition data pointer forRichard Smith2014-05-223-6/+6

* Don't reduce the stack protector level given -fstack-protector.Rafael Espindola2014-05-221-3/+4
| | | | | | | | | Before -fstack-protector would always force a level of 1, even if the default was 2. Patch by Brad Smith. llvm-svn: 209479

* Unify the name of compiler-rt builtins library on Linux.Alexey Samsonov2014-05-221-3/+4
| | | | | | | | | | Call it "libclang_rt.builtins-<arch>.a" to be consistent with sanitizers/profile libraries naming. Modify Makefile and CMake build systems and Clang driver accordingly. Fixes PR19822. llvm-svn: 209474
* If a class template specialization from one module has its definitionRichard Smith2014-05-222-0/+23

We'll need them if someone imports the second module and tries to instantiate a member of the template. llvm-svn: 209472

* Remove limits on the number of fix-it hints and ranges in the DiagnosticsEngine.Alexander Kornienko2014-05-225-31/+14
| | | | | | | | | | | | | | | | | | | Summary: The limits on the number of fix-it hints and ranges attached to a diagnostic are arbitrary and don't apply universally to all users of the DiagnosticsEngine. The way the limits are enforced may lead to diagnostics generating invalid sets of fixes. I suggest removing the limits, which will also simplify the implementation.

* clang-format: Introduce DisableFormat that prevents formatting.Daniel Jasper2014-05-221-0/+16
| | | | | | | | | | | | | | | | | And "none" pseudo-style indicating that formatting should be not applied. (1) Using .clang-format with "DisableFormat: true" effectively prevents formatting for all files within the folder containing such .clang-format file. (2) Using -fallback-style=none together with -style=file prevents formatting when .clang-format is not found, which can be used in on-save callback. Patch by Adam Strzelecki. Thank you! llvm-svn: 209446
* clang-format: Don't use Allman brace breaking for ObjC blocks.Daniel Jasper2014-05-221-1/+2

* MachO: look for nearby tools on all MachO platforms.Tim Northover2014-05-221-8/+8
| | | | | | | | | | | | | This brings "-arch armv7m" (etc) behaviour more in line with what's expected for developers on OS X, and allows Clang to find an "ld" (for example) in the same directory instead of using the default /usr/bin/ld. Unfortunately no test because it relies on the specific place Clang is running from. rdar://problem/16427320 llvm-svn: 209437

* clang-format: Store pointers to seen formatting states.Daniel Jasper2014-05-221-2/+8
| | | | | | | | | | | As the memory ownership is handled by the SpecificBumpPtrAllocator anyway, there is no need to duplicate states when inserting them into the Seen-set. This leads to an improvement of ~10% on the benchmark formatting file. No functional changes intended. llvm-svn: 209422

* clang-format: Correctly calculate line lenghts for nest blocks.Daniel Jasper2014-05-222-9/+17
| | | | | | | | | | | | | | | If simple (one-statement) blocks can be inlined, the length needs to be calculated correctly. Before (in JavaScript but this also affects lambdas, etc.): var x = { valueOf: function() { return 1; } }; After: var x = {valueOf: function() { return 1; }}; llvm-svn: 209410
* Frontend: Propagate ASTReaderListener API in ChainedASTReaderListenerJustin Bogner2014-05-221-2/+8
| | | | | | | | | | | | | | | | | ASTReaderListener's documentation states that visitInputFile will be called based on the return values of needsInputFileVisitation and needsSystemInputFileVisitation, but ChainedASTReaderListener may call these methods on a child listener based on the values returned by the other child. Even worse, the calls to visitInputFile may be short-circuited due to the use of the boolean or, so the calls to visit may not occur at all for the second listener. This updates ChainedASTReaderListener::visitInputFile to propagate the ASTReaderListener behaviour to both children. llvm-svn: 209394

* Make the parent-map use significantly less memory.Manuel Klimek2014-05-211-3/+37
| | | | | | | | | | | On test files I ran this on, memory consumption overall went down from 2.5G to 2G, without performance regressions. I also investigated making DynTypedNode by itself smaller (by pulling out pointers for everything that doesn't fit in 8 bytes). This led to another 200-300MB saved, but also introduced a significant regression in performance due to the memory management overhead. llvm-svn: 209297
