* Attempt to fix build after r244912Ben Langmuir2015-08-131-4/+7
| | | | | | | Some compilers were less happy about converting a lambda to a comparator function for array_pod_sort. llvm-svn: 244917
* [Modules] Add Darwin-specific compatibility module map parsing hacksBen Langmuir2015-08-132-7/+100
| | | | | | | | | | | | | | | | This preserves backwards compatibility for two hacks in the Darwin system module map files: 1. The use of 'requires excluded' to make headers non-modular, which should really be mapped to 'textual' now that we have this feature. 2. Silently removes a bogus cplusplus requirement from IOKit.avc. Once we start diagnosing missing requirements and headers on auto-imports these would have broken compatibility with existing Darwin SDKs. llvm-svn: 244912

* Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.Ivan Krasin2015-08-134-27/+54
| | | | | | | | | | | | | | | | | | | Summary: Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer, Control Flow Integrity and others, use blacklists to specify which types / functions should not be instrumented to avoid false positives or suppress known failures. This change adds the blacklist filenames to the list of dependencies of the rules, generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain C/C++/ObjC files need to be recompiled (if a blacklist is updated).

| | | | | | | | | | | | | | | | | poisoning fields inherited from base classes. Verify emitted code for derived class with virtual destructor sanitizes its members only once. Changed emission order for dtor callback, so only the last dtor for a class emits the sanitizing callback, while ensuring that class members are poisoned before base class destructors are invoked. Skip poisoning of members, if class has no fields. Removed patch file containing extraneous changes.

* Stop printing macro backtraces that don't help diagnostics.Richard Trieu2015-08-121-0/+39
| | | | | | | | | | | | | | | When displaying the macro backtrace, ignore some of the backtraces that do not provide extra information to the diagnostic. Typically, if the problem is entirely contained within a macro argument, the macro expansion is often not needed. Also take into account SourceRange's attached to the diagnostic when selecting which backtraces to ignore. Two previous test cases have also been updated.

* Print vectorization analysis when loop hint is specified.Tyler Nowicki2015-08-111-15/+21
| | | | | | This patche and a related llvm patch solve the problem of having to explicitly enable analysis when specifying a loop hint pragma to get the diagnostics. Passing AlwasyPrint as the pass name (see below) causes the front-end to print the diagnostic if the user has specified '-Rpass-analysis' without an '=<target-pass>’. Users of loop hints can pass that compiler option without having to specify the pass and they will get diagnostics for only those loops with loop hints. llvm-svn: 244556

* [dllimport] A non-imported class with an imported key can't have a keyReid Kleckner2015-08-101-0/+6
| | | | | | | | | | | | | | | | | Summary: The vtable takes its DLL storage class from the class, not the key function. When they disagree, the vtable won't be exported by the DLL that defines the key function. The easiest way to ensure that importers of the class emit their own vtable is to say that the class has no key function.

* Add new llvm.loop.unroll.enable metadata for use with "#pragma unroll".Mark Heffernan2015-08-104-55/+83
| | | | | | | | | | | | | | | | | | | | | | This change adds the new unroll metadata "llvm.loop.unroll.enable" which directs the optimizer to unroll a loop fully if the trip count is known at compile time, and unroll partially if the trip count is not known at compile time. This differs from "llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not known at compile time With this change "#pragma unroll" generates "llvm.loop.unroll.enable" rather than "llvm.loop.unroll.full" metadata. This changes the semantics of "#pragma unroll" slightly to mean "unroll aggressively (fully or partially)" rather than "unroll fully or not at all". The motivating example for this change was some internal code with a loop marked with "#pragma unroll" which only sometimes had a compile-time trip count depending on template magic. When the trip count was a compile-time constant, everything works as expected and the loop is fully unrolled. However, when the trip count was not a compile-time constant the "#pragma unroll" explicitly disabled unrolling of the loop(!). Removing "#pragma unroll" caused the loop to be unrolled partially which was desirable from a performance perspective. llvm-svn: 244467

* [Driver] Fix handling of -fbuiltin/-fcommon when combined with -mkernelJohn Brawn2015-08-101-18/+10
| | | | | | | | | | | -mkernel enables -fno-builtin and -fno-common by default, but allows -fbuiltin and -fcommon to override that. However "-fbuiltin -fno-builtin" is treated the same as "-fbuiltin" which is wrong, so fix that. Also fixes similar behaviour when -fno-common is default.
