* [X86] Lower blended PACKUSes using appropriate types.Ahmed Bougacha2016-06-292-11/+73
| | | | | | | | | | | | | When lowering two blended PACKUS, we used to disregard the types of the PACKUS inputs, indiscriminately generating a v16i8 PACKUS. This leads to non-selectable things like: (v16i8 (PACKUS (v4i32 v0), (v4i32 v1))) Instead, check that the PACKUSes have the same type, and use that as the final result type. llvm-svn: 274138

* [llvm-cov] Do not allow ".." to escape the coverage sub-directoryVedant Kumar2016-06-294-2/+22
| | | | | | | | | | | In -output-dir mode, file reports are placed into a "coverage" directory. If filenames in the coverage mapping contain "..", they might escape out of this directory. Fix the problem by removing ".." from source filenames (expand the path component). llvm-svn: 274135

* [ManagedStatic] Reimplement double-checked locking with std::atomic.Benjamin Kramer2016-06-292-40/+17
| | | | | | | | | | | | | This gets rid of the memory fence in the hot path (dereferencing the ManagedStatic), trading for an extra mutex lock in the cold path (when the ManagedStatic was uninitialized). Since this only happens on the first accesses it shouldn't matter much. On strict architectures like x86 this removes any atomic instructions from the hot path. Also remove the tsan annotations, tsan knows how standard atomics work so they should be unnecessary now. llvm-svn: 274131

* Remove platform plugins from lldb-serverPavel Labath2016-06-297-120/+47
| | | | | | | | | | | | | | | | | | | Summary: This removes the last usage of Platform plugins in lldb-server -- it was used for launching child processes, where it can be trivially replaced by Host::LaunchProces (as lldb-server is always running on the host). Removing platform plugins enables us to remove a lot of other unused code, which was pulled in as a transitive dependency, and it reduces lldb-server size by 4%--9% (depending on build type and architecture).

* [ELF] - Added support for --unresolved-symbols option.George Rimar2016-06-296-12/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Option has next description (http://linux.die.net/man/1/ld): "--unresolved-symbols=method Determine how to handle unresolved symbols. There are four possible values for method according to documentation: ignore-all: Do not report any unresolved symbols. report-all: Report all unresolved symbols. This is the default. ignore-in-object-files: Report unresolved symbols that are contained in shared libraries, but ignore them if they come from regular object files. ignore-in-shared-libs: Report unresolved symbols that come from regular object files, but ignore them if they come from shared libraries." Since report-all is default and we traditionally do not report about undefined symbols in lld, report-all does not report about undefines from DSO. ignore-in-object-files also does not do that. Handling of that option differs from what gnu linkers do. Option works in next way in lld: ignore-all: Do not report any unresolved symbols. report-all: Report all unresolved symbols except symbols from DSOs. This is the default. ignore-in-object-files: The same as ignore-all. gnore-in-shared-libs: The same as report-all. This is PR24524.

* [LLDB][MIPS] Check if libatomic needs to be specified explicitlySagar Thakur2016-06-291-0/+5
| | | | | | | | | | | Patch by Nitesh Jain. Summary : The problem appears while linking liblldb.so. The class Address contain atomic variable m_offset. The loading and storing of variable is access via atomic_load_8 and atomic_store_8 functions. Some target fail to implicitly link libatomic, which cause undefine reference to atomic_store_8/atomic_load_8. This patch uses http://reviews.llvm.org/D20896 to check if libatomic need to be explicitly link. Reviewed by labath. Differential: D20464 llvm-svn: 274121

* [tsan] Stop extending the block’s lifetime in dispatch_group_asyncKuba Brecka2016-06-292-1/+46
| | | | | | | | The dispatch_group_async interceptor actually extends the lifetime of the executed block. This means the destructor of the block (and captured variables) is called *after* dispatch_group_leave, which changes the semantics of dispatch_group_async. This patch fixes that.

| | | | | | | | | | | | a recurrence with a NSW addition. If a operation for a recurrence is an addition with no signed wrap and both input sign bits are 0, then the result sign bit must also be 0. Similar for the negative case. I found this deficiency while playing around with a loop in the x86 backend that contained a signed division that could be optimized into an unsigned division if we could prove both inputs were positive. One of them being the loop induction variable. With this patch we can perform the conversion for this case. One of the test cases here is a contrived variation of the loop I was looking at.
