* [Sparc] Mark i128 shift libcalls unavailable in 32-bit mode.James Y Knight2016-09-021-0/+7
| | | | | | | | | | | Recently, llvm wants to emit calls to these functions, while it didn't seem to be an issue before. Not sure why. Nor do I know why only these three are important to disable, out of all of the i128 libcalls. Nevertheless, many other targets have this snippet of code, so, just copying it to sparc as well, to unbreak things. llvm-svn: 280537
* Use od instead of hexdump.Rui Ueyama2016-09-021-3/+3

* Implement __attribute__((require_constant_initialization)) for safe static ↵Eric Fiselier2016-09-028-27/+393
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initialization. Summary: This attribute specifies expectations about the initialization of static and thread local variables. Specifically that the variable has a [constant initializer](http://en.cppreference.com/w/cpp/language/constant_initialization) according to the rules of [basic.start.static]. Failure to meet this expectation will result in an error. Static objects with constant initializers avoid hard-to-find bugs caused by the indeterminate order of dynamic initialization. They can also be safely used by other static constructors across translation units. This attribute acts as a compile time assertion that the requirements for constant initialization have been met. Since these requirements change between dialects and have subtle pitfalls it's important to fail fast instead of silently falling back on dynamic initialization. ```c++ // -std=c++14 #define SAFE_STATIC __attribute__((require_constant_initialization)) static struct T { constexpr T(int) {} ~T(); }; SAFE_STATIC T x = {42}; // OK. SAFE_STATIC T y = 42; // error: variable does not have a constant initializer // copy initialization is not a constant expression on a non-literal type. ``` This attribute can only be applied to objects with static or thread-local storage duration.

* Dispatch without hash table lookup.Rui Ueyama2016-09-021-19/+25
| | | | | | | | | | | Cmd used to be the single central place to dispatch. It is not longer the case because we have a logic for readProvideOrAssignment(). This patch removes the hash table so that evrything is in a single function. This is slightly verbose but should improve readability.

* Use 'critical' reduction method when 'atomic' is not available but requested.Jonathan Peyton2016-09-022-8/+16
| | | | | | | | | | | | | In case atomic reduction method is not available (the compiler can't generate it) the assertion failure occurred if KMP_FORCE_REDUCTION=atomic was specified. This change replaces the assertion with a warning and sets the reduction method to the default one - 'critical'.

* IfConversion: Add assertions that both sides of a diamond don't pred-clobber.Kyle Butt2016-09-021-2/+3
| | | | | | | | | One side of a diamond may end with a predicate clobbering instruction. That side of the diamond has to be if-converted second. Both sides can't clobber the predicate or the ifconversion is invalid. This is checked elsewhere, but add an assert as a safety check. NFC llvm-svn: 280518

* Remove temoprary files.Rui Ueyama2016-09-021-36/+60
| | | | | | | | | | | | | | Previously, we created temporary files using llvm::sys::fs::createTemporaryFile and removed them using llvm::FileRemover. This is error-prone as it is easy to forget creating FileRemover instances after creating temporary files. There is actually a temporary file leak bug. This patch introduces a new class, TemporaryFile, to manage temporary files in the RAII style. Differential Revision: https://reviews.llvm.org/D24176 llvm-svn: 280510
* [SE] GlobalDeviceMemory owns its handleJason Henline2016-09-026-143/+123
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Final step in getting GlobalDeviceMemory to own its handle. * Make GlobalDeviceMemory movable, but no longer copyable. * Make Device::freeDeviceMemory function private and make GlobalDeviceMemoryBase a friend of Device so GlobalDeviceMemoryBase can free its memory in its destructor. * Make GlobalDeviceMemory constructor private and make Device a friend so it can construct GlobalDeviceMemory. * Remove SharedDeviceMemoryBase class because it is never used. * Remove explicit memory freeing from example code. This change just consumes any errors generated during device memory freeing. The real error handling will be added in a future patch.

* Fix potential test failures.Rui Ueyama2016-09-025-9/+11
| | | | | | | | | | | | | | | | | Windows does not allow opened files to be removed. This patch fixes two types of errors. - Output file being the same as input file. Because LLD itself holds a file descriptor of the input file, it cannot create an output file with the same name as a new file. - Removing files before releasing MemoryBuffer objects. These tests are not failing no because MemoryBuffer happens to decide not to use mmap on these files. But we shouldn't rely on that behavior. llvm-svn: 280507

* Split the store of a wide value merged from an int-fp pair into multiple stores.Wei Mi2016-09-024-0/+191
| | | | | | | | | | | | | | For the store of a wide value merged from a pair of values, especially int-fp pair, sometimes it is more efficent to split it into separate narrow stores, which can remove the bitwise instructions or sink them to colder places. Now the feature is only enabled on x86 target, and only store of int-fp pair is splitted. It is possible that the application scope gets extended with perf evidence support in the future.

* [LV] Ensure reverse interleaved group GEPs remain uniformMatthew Simpson2016-09-022-3/+19
| | | | | | | | | | | | | | For uniform instructions, we're only required to generate a scalar value for the first vector lane of each unroll iteration. Thus, if we have a reverse interleaved group, computing the member index off the scalar GEP corresponding to the last vector lane of its pointer operand technically makes the GEP non-uniform. We should compute the member index off the first scalar GEP instead. I've added the updated member index computation to the existing reverse interleaved group test. llvm-svn: 280497

* [instsimplify] Fix incorrect folding of an ordered fcmp with a vector of all ↵Andrea Di Biagio2016-09-022-1/+9
| | | | | | | | | | | | | | | | | | | | | | | NaN. This patch fixes a crash caused by an incorrect folding of an ordered comparison between a packed floating point vector and a splat vector of NaN. An ordered comparison between a vector and a constant vector of NaN, should always be folded into a constant vector where each element is i1 false. Since revision 266175, SimplifyFCmpInst folds the ordered fcmp into a scalar 'false'. Later on, this would cause an assertion failure, since the value type of the folded value doesn't match the expected value type of the uses of the original instruction: "Assertion failed: New->getType() == getType() && "replaceAllUses of value with new value of different type!". This patch fixes the issue and adds a test case to the already existing test InstSimplify/floating-point-compares.ll. Differential Revision: https://reviews.llvm.org/D24143 llvm-svn: 280488
