* [SystemZ] Define __GCC_HAVE_SYNC_COMPARE_AND_SWAP macrosUlrich Weigand2016-02-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_[1248] macros on SystemZ. This fixes a miscompile of GCC C++11 standard library headers due to use of those macros in an ABI-changing manner. See e.g. /usr/include/c++/4.8.5/ext/concurrence.h: // Compile time constant that indicates prefered locking policy in // the current configuration. static const _Lock_policy __default_lock_policy = #ifdef __GTHREADS #if (defined(__GCC_HAVE_SYNC_COMPARE_AND_SWAP_2) \ && defined(__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4)) _S_atomic; #else _S_mutex; #endif #else _S_single; #endif A different choice of __default_lock_policy causes different sizes of several of the C++11 data structures, which are then incompatible when inlined in clang-compiled code with what the (GCC-compiled) external library expects. This in turn leads to various crashes when using std::thread in code compiled with clang, as see e.g. via the ThreadPool unit tests. See PR 26473 for an example. llvm-svn: 259931
* Do not honor explicit alignment attribute on fields for PS4.Sunil Srivastava2016-02-052-0/+5

* [modules] Separately track whether an identifier's preprocessor information andRichard Smith2016-02-051-0/+1

For a C++ modules build, we do not need to re-emit the identifier into the serialized identifier table if only the name lookup information has changed (and in all cases, we don't need to re-emit the macro information if only the name lookup information has changed). llvm-svn: 259901

* Basic: mark TLS as supported on Windows on ARMSaleem Abdulrasool2016-02-041-1/+0

* [OpenMP] Parsing + sema for target parallel for directive.Arpith Chacko Jacob2016-02-031-9/+20

* [OpenCL] Adding reserved operator logical xor for OpenCLAnastasia Stulova2016-02-031-0/+1
| | | | | | | | | | | | | | | | | | This patch adds the reserved operator ^^ when compiling for OpenCL (spec v1.1 s6.3.g), which results in a more meaningful error message. Patch by Neil Hickey!

* -inline-asm][X86] Add ability to use AVX512 in MS inline asmMarina Yatsina2016-02-031-0/+8

* Fix attribute((mode([word|unwind_word]))) for x32Reid Kleckner2016-02-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch by H.J. Lu ``` typedef unsigned int gcc_word __attribute__((mode(word))); ``` and ``` typedef unsigned int gcc_unwind_word __attribute__((mode(unwind_word))); ``` define the largest unsigned integer types which can be stored in a general purpose register, which may not be the pointer type. For x32, they aren't pointer nor unsigned long. We should 1. Make getUnwindWordWidth and getRegisterWidth virtual, 2. Override them for x32, similar to hasInt128Type. 3. Use getRegisterWidth for __attribute__((mode(word))); This fixes PR 24706. Reviewers: rnk Differential Revision: http://reviews.llvm.org/D16779 llvm-svn: 259383

| | | | | | | | Various bits we'd like to use the new ABI actually compile with "-arch armv7k -miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how slices work. llvm-svn: 258976
* Revert "Change of UserLabelPrefix default value from "_" to """James Y Knight2016-01-272-23/+32
| | | | | | | | | | | | | This reverts commit r258504. This commit breaks (at least) sparc-rtems -- the OS (RTEMS) used to override UserLabelPrefix to "", despite the arch (SPARC) having set it to "_". Now, the OS doesn't override anymore, but the arch sets it to "_", resulting in the wrong value. I expect this probably breaks other OSes that overrode to "" before, as well. (Clearly we have some missing test cases, here...) llvm-svn: 258894

| | | | | | | | | | | | | | | | | Fix arc patch fuzz error. Summary: Support for the pipe built-in functions for OpenCL 2.0. The pipe builtin functions may have infinite kinds of element types, one approach would be to just generate calls that would always use generic types such as void*.
