* [OPENMP] Fix for http://llvm.org/PR25878: Error compiling an OpenMP programAlexey Bataev2015-12-182-6/+80
| | | | | | OpenMP codegen tried to emit the code for its constructs even if it was detected as a dead-code. Added checks to ensure that the code is emitted if the code is not dead. llvm-svn: 255990

* Attach maximum function count to Module when using PGO mode.Easwaran Raman2015-12-171-2/+5
| | | | | | | | This sets the maximum entry count among all functions in the program to the module using module flags. This allows the optimizer to use this information. Differential Revision: http://reviews.llvm.org/D15163 llvm-svn: 255918
* [CUDA] Make vtable construction aware of host/device side of CUDA compilation.Artem Belevich2015-12-172-0/+33
| | | | | | | | | | | | | | | | | | | C++ emits vtables for classes that have key function present in the current TU. While we compile CUDA the fact that key function was found in this TU does not mean that we are going to generate code for it. E.g. vtable for a class with host-only methods should not (and can not) be generated on device side, because we'll never generate code for them during device-side compilation. This patch adds an extra CUDA-specific check during key method computation and filters out potential key methods that are not suitable for this side of CUDA compilation. When we codegen vtable, entries for unsuitable methods are set to null. Differential Revision: http://reviews.llvm.org/D15309 llvm-svn: 255911

* [analyzer] Better detect when C++ object was constructed into existing region.Devin Coughlin2015-12-173-38/+101
| | | | | | | | | | | | | | | | | | | | | | | | | When the analyzer evaluates a CXXConstructExpr, it looks ahead in the CFG for the current block to detect what region the object should be constructed into. If the constructor was directly constructed into a local variable or field region then there is no need to explicitly bind the constructed value to the local or field when analyzing the DeclStmt or CXXCtorInitializer that called the constructor. Unfortunately, there were situations in which the CXXConstructExpr was constructed into a temporary region but when evaluating the corresponding DeclStmt or CXXCtorInitializer the analyzer assumed the object was constructed into the local or field. This led to spurious warnings about uninitialized values (PR25777). To avoid these false positives, this commit factors out the logic for determining when a CXXConstructExpr will be directly constructed into existing storage, adds the inverse logic to detect when the corresponding later bind can be safely skipped, and adds assertions to make sure these two checks are in sync. rdar://problem/21947725 llvm-svn: 255859

* [CUDA] renamed cuda_runtime.h wrapper to __cuda_runtime.hArtem Belevich2015-12-163-11/+27
| | | | | | | | | | | | | | Currently it's easy to break CUDA compilation by passing "-isystem /path/to/cuda/include" to compiler which leads to compiler including real cuda_runtime.h from there instead of the wrapper we need. Renaming the wrapper ensures that we can include the wrapper regardless of user-specified include paths and files. Differential Revision: http://reviews.llvm.org/D15534 llvm-svn: 255802

| | | | | | | | | | Specifically, it is sometimes necessary to keep certain #includes as the first #include, even before the main #include for a .cc file.

| | | | | | | | | | | | | | | | | | | | | Clang doesn’t support a use of “this” pointer inside inline asm. When I tried to compile a class or a struct (see example) with an inline asm that contains "this" pointer. Clang returns with an error.

* [libclang] Add a flag to create the precompiled preamble on the first parse.Benjamin Kramer2015-12-151-16/+19
| | | | | | | | | | | | | | | | | | | | | Summary: The current default is to create the preamble on the first reparse, aka second parse. This is useful for clients that do not want to block when opening a file because serializing the preamble takes a bit of time. However, this makes the reparse much more expensive and that may be on the critical path as it's the first interaction a user has with the source code. YouCompleteMe currently optimizes for the first code interaction by parsing the file twice when loaded. That's just unnecessarily slow and this flag helps to avoid that.

* [Sema] Make nullness warnings appear in C++.George Burgess IV2015-12-142-12/+22
| | | | | | | | | | | | | | | | | | | Given the following code: int *_Nullable ptr; int *_Nonnull nn = ptr; ...In C, clang will warn you about `nn = ptr`, because you're assigning a nonnull pointer to a nullable pointer. In C++, clang issues no such warning. This patch helps ensure that clang doesn't ever miss an opportunity to complain about C++ code. N.B. Though this patch has a differential revision link, the actual review took place over email. Differential Revision: http://reviews.llvm.org/D14938 llvm-svn: 255556
* Reordering fields to reduce padding in Clang. NFCBen Craig2015-12-142-11/+11
| | | | llvm-svn: 255552
* [PATCH] Adding checker to detect excess padding in recordsBen Craig2015-12-143-0/+329
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intent of this checker is to generate a report for any class / structure that could reduce its padding by reordering the fields. This results in a very noisy checker. To reduce the noise, this checker will currently only warn when the number of bytes over "optimal" is more than 24. This value is configurable with -analyzer-config performance.Padding:AllowedPad=N. Small values of AllowedPad have the potential to generate hundreds of reports, and gigabytes of HTML reports. The checker searches for padding violations in two main ways. First, it goes record by record. A report is generated if the fields could be reordered in a way that reduces the padding by more than AllowedPad bytes. Second, the checker will generate a report if an array will cause more than AllowedPad padding bytes to be generated. The record checker currently skips many ABI specific cases. Classes with base classes are skipped because base class tail padding is ABI specific. Bitfields are just plain hard, and duplicating that code seems like a bad idea. VLAs are both uncommon and non-trivial to fix. The array checker isn't very thorough right now. It only checks to see if the element type's fields could be reordered, and it doesn't recursively check to see if any of the fields' fields could be reordered. At some point in the future, it would be nice if "arrays" could also look at array new usages and malloc patterns that appear to be creating arrays. llvm-svn: 255545

* [MS ABI] Don't rely on terminatepadDavid Majnemer2015-12-141-7/+6
| | | | | | | | | | | | | | | We'd like to remove support for terminatepad from LLVM. To do this, we need to move Clang off of it first. The intent behind terminatepad was to carefully model exception specifications for the MSVC personality. However, we don't support exception specifications for the MSVC personality and neither does MSVC. Instead, MSVC supports all-or-nothing exception specifications. We can model this limited usage using cleanuppads which call std::terminate. Differential Revision: http://reviews.llvm.org/D15478 llvm-svn: 255521
