* [ARM|RT] Merging r24766 into 3.9.1release_39Renato Golin2016-12-021-2/+17
| | | | | | | Fixes a bug encountered in RC2 validation. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/branches/release_39@288513 91177308-0d34-0410-b5e6-96231b3b80d8
* [3.9.1] Merging r287359:Renato Golin2016-11-192-0/+66
| | | | | | | | | | | | | | | | | | | | | builtins: repair the builtins build with clang 3.8 When the C unwinding personality was corrected to match the ARM EHABI specification, the unwind header in clang was updated with necessary declarations. However, when building with an older compiler, we would not have the necessary declarations. This would result in a build failure. Provide a supplementary header to ensure that the necessary declarations are present for the build of the C unwinding personality. Note that this is NOT an ABI break. It merely is a compile time failure due to the constants not being present. The constants here are reproduced equivalently. This header should permit building with clang[<3.9] as well as gcc.

| | | | | | | | | | | | | | | | | | | | | Summary: This aims to add support for __cpu_model and address Bug 25510. It uses the code from lib/Support/Host.cpp for cpu detection, and creates __cpu_model with that info. Tested on OSX and built on Linux as well (though libgcc is the default). The use of "asm" required -std=gnu99, hence the cmake change. Corrections on better addressing this are welcome. Previously reverted, up for review again to iron out outstanding issues.

* [compiler-rt] Fix VisualStudio virtual folders layoutEtienne Bergeron2016-07-1129-47/+76
| | | | | | | | | | | | | | | | | | | | Summary: This patch is a refactoring of the way cmake 'targets' are grouped. It won't affect non-UI cmake-generators. Clang/LLVM are using a structured way to group targets which ease navigation through Visual Studio UI. The Compiler-RT projects differ from the way Clang/LLVM are grouping targets. This patch doesn't contain behavior changes.

* test: Use %clangxx in objc++ test filesSaleem Abdulrasool2016-07-098-9/+9
| | | | | | | | | | These test in this change are objc++, but are built using %clang, not %clangxx. The reason this works is the driver has been adding -lc++ for sanitizer enabled builds. By making these tests use %clangxx, they no longer depend on the driver linking to c++. Doing so will allow us to prevent overlinking of libc++ for applications. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@274989 91177308-0d34-0410-b5e6-96231b3b80d8
* [esan] Add __esan_report for mid-run dataDerek Bruening2016-07-0911-5/+166
| | | | | | | | | | | | | | | | | | | | | Summary: Adds a new public interface routine __esan_report() which can be used to request profiling results prior to abnormal termination (e.g., for a server process killed by its parent where the normal exit does not allow for normal result reporting). Implements this for the working-set tool. The cache frag tool is left unimplemented as it requires missing iteration capabilities. Adds a new test.

* Revert "Add runtime support for __cpu_model (__builtin_cpu_supports)"Alina Sbirlea2016-07-083-820/+1
| | | | | | This reverts commit r274873 until additional fixes are resolved. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@274944 91177308-0d34-0410-b5e6-96231b3b80d8
* Add runtime support for __cpu_model (__builtin_cpu_supports)Alina Sbirlea2016-07-083-1/+820
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This aims to add support for __cpu_model and address Bug 25510. It uses the code from lib/Support/Host.cpp for cpu detection, and creates __cpu_model with that info. Tested on OSX, it builts successfully, but the current version does *not* resolve Bug 25510. The __cpu_model symbol is present in the library but it only gets loaded with -all_load. This patch will not land until this issue is clarified. Built on Linux as well (though libgcc is the default). The use of "asm" required -std=gnu99, hence the cmake change. Corrections on better addressing this are welcome. Note: See additional comments on D20988 (committed as r271921).
