* [dfsan] Run the tests for each supported arch and suffix each one to ↵Daniel Sanders2016-02-093-6/+37
| | | | | | | | | | | | | | | | | | | | | | | distinguish them. Summary: Previously, the tests only ran for the 64-bit equivalent of the default target (see -m64). Given the supported architecture list only contains 64-bit targets, this happens to work out the same as the supported targets in most cases but may matter for X86_64/X86_64h on Darwin. For other targets, the practical effect is that the test names contain the architecture. This resolves some confusion when msan tests fail since their name no longer implies that they are trying to test the default target.

* Use the plt entry as the address of some symbols.Rafael Espindola2016-02-099-49/+83
| | | | | | | | | | | | | | | This is the function equivalent of a copy relocation. Since functions are expected to change sizes, we cannot use copy relocations. In situations where one would be needed, what is done instead is: * Create a plt entry * Output an undefined symbol whose addr is the plt entry. The dynamic linker makes sure any shared library uses the plt entry as the function address. llvm-svn: 260224

* [X86][AVX2] Fix SIGN_EXTEND vector handling on AVX2 targets.Simon Pilgrim2016-02-093-20/+24
| | | | | | | | | | On AVX2 target we are poorly legalizing SIGN_EXTEND ops for which the input's legalized type doesn't have the same number of elements as the destination, resulting in an ANY_EXTEND followed by a SIGN_EXTEND_INREG. This patch uses the existing SIGN_EXTEND -> SIGN_EXTEND_VECTOR_INREG combine to extend the input to the size of the result and using SIGN_EXTEND_VECTOR_INREG instead.

* [GCC] GOMP_task: Change argument type of if_cond from int to boolJonas Hahnfeld2016-02-091-1/+1
| | | | | | | | | | | | (libgomp has bool as well) This was causing a test failure in omp_test_if.c when building with GCC in Debug mode. I have verified that GCC versions 4.9.2 and 5.3.0 now work and compile-tested this change with clang 3.7.1 and Intel Compiler 16.0.

* [CMake] Providing a CMake cache for 3-stage buildsChris Bieneman2016-02-091-0/+34
| | | | | | | | | | | | This cache file can be used to generate a 3-stage clang build. You can configure using the following CMake command: cmake -C <path to clang>/cmake/caches/3-stage.cmake -G Ninja <path to llvm> You can then run "ninja stage3-clang" to build stage1, stage2 and stage3 clangs. This is useful for finding non-determinism the compiler by verifying that stage2 and stage3 are identical. llvm-svn: 260201

* Fix an issue where pressing CTRL+C in the interactive script interpreter ↵Enrico Granata2016-02-091-1/+1
| | | | | | | | | | | | causes LLDB to crash This is because PyThreadState_Get() assumes a non-NULL thread state and crashes otherwise; but PyThreadState_GET is just a shortcut (in non-Python-debugging builds) for the global variable that holds the thread state The behavior of CTRL+C is slightly more erratic than one would like. CTRL+C in the middle of execution of Python code will cause that execution to be interrupted (e.g. time.sleep(1000)), but a CTRL+C at the prompt will just cause a KeyboardInterrupt and not exit the interpreter - worse, it will only trigger the exception once one presses ENTER. None of this is optimal, of course, but I don't have a lot of time to appease the Python deities with the proper spells right now, and fixing the crasher is already a good thing in and of itself llvm-svn: 260199

* Refactor PGO function naming and MD5 hashing support out of ProfileDataTeresa Johnson2016-02-095-31/+47
| | | | | | | | | | | | | | | | | | | | Summary: Move the function renaming logic into the Function class, and the MD5Hash routine into the MD5 header. This will enable these routines to be shared with ThinLTO, which will be changed to store the MD5 hash instead of full function name in the combined index for significant size reductions. And using the same function naming for locals in the function index facilitates future integration with indirect call value profiles.

* Add cmdline options for LC_DATA_IN_CODE load command.Pete Cooper2016-02-097-7/+111
| | | | | | | | | | | | Also added the defaults for whether to generate this load command, which the cmdline options are able to override. There was also a difference to ld64 which is fixed here in that ld64 will generate an empty data in code command if requested. rdar://problem/24472630 llvm-svn: 260191
* Remove TrailingObjects::operator delete. It's still suffering fromRichard Smith2016-02-093-8/+4
| | | | | | | | | compiler-specific issues. Instead, repeat an 'operator delete' definition in each derived class that is actually deleted, and give up on the static type safety of an error when sized delete is accidentally used on a type derived from TrailingObjects. llvm-svn: 260190

* Generate LC_FUNCTION_STARTS load command.Pete Cooper2016-02-098-43/+238
| | | | | | | | | | | | | | This load command generates data in the LINKEDIT section which is a list of ULEB128 delta's to all of the functions in the __text section. It is then 0 terminated and pointer aligned to pad. ld64 exposes the -function-starts and no-function-starts cmdline options to override behaviour from the defaults based on file types. rdar://problem/24472630 llvm-svn: 260188

* Reorder enum entry as its used for atom sorting.Pete Cooper2016-02-092-1/+2
| | | | | | | | | | The atom content type enum is used as a tie breaker to sort atoms. In that case, we want MachHeader to be before typeCode as it really will be before the code in the final executable. Test case to follow in the next commit or two. llvm-svn: 260184
* Add an "addUsedAAAnalyses" helper functionSanjoy Das2016-02-096-0/+32
| | | | | | | | | | | | | | | | | | | Summary: Passes that call `getAnalysisIfAvailable<T>` also need to call `addUsedIfAvailable<T>` in `getAnalysisUsage` to indicate to the legacy pass manager that it uses `T`. This contract was being violated by passes that used `createLegacyPMAAResults`. This change fixes this by exposing a helper in AliasAnalysis.h, `addUsedAAAnalyses`, that is complementary to createLegacyPMAAResults and does the right thing when called from `getAnalysisUsage`.
