* [FileManager] Don't crash if reading from stdin and stat(".") failsDavid Majnemer2016-04-121-1/+1
| | | | | | | | | | | | | addAncestorsAsVirtualDirs("<stdin>") quickly returns without doing work because "<stdin>" has no parent_path. This violates the expectation that a subsequent call to getDirectoryFromFile("<stdin>") would succeed. Instead, it fails because it uses the "." if the file has no path component. Fix this by keeping the behavior between addAncestorsAsVirtualDirs and getDirectoryFromFile symmetric. llvm-svn: 266089
* AMDGPU/SI: Fix a mis-compilation of multi-level breaksNicolai Haehnle2016-04-122-0/+57
| | | | | | | | | | | | | | | | | | Summary: Under certain circumstances, multi-level breaks (or what is understood by the control flow passes as such) could be miscompiled in a way that causes infinite loops, by emitting incorrect control flow intrinsics.

* Do not by default minimize remarksJohannes Doerfert2016-04-123-10/+20
| | | | | | | | | | | | | We used checks to minimize the number of remarks we present to a user but these checks can become expensive, especially since all wrapping assumptions are emitted separately. Because there is not benefit for a "headless" run we put these checks under a command line flag. Thus, if the flag is not given we will emit "non-effective" remarks, e.g., duplicates and revert to the old behaviour if it is given. As this also changes the internal representation of some sets we set the flag by default for our unit tests. llvm-svn: 266087
* Support arbitrary addrspace pointers in masked load/store intrinsicsArtur Pilipenko2016-04-1212-206/+339
| | | | | | | | | | | | | | This is a resubmittion of 263158 change. This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace. The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics. Reviewed By: reames Differential Revision: http://reviews.llvm.org/D17270 llvm-svn: 266086

* [ScheduleDAGInstrs] Handle instructions with multiple MMOsGeoff Berry2016-04-122-30/+64
| | | | | | | | | | | | | | | | | | | | | Summary: In getUnderlyingObjectsForInstr(): Don't give up on instructions with multiple MMOs, instead look through all the MMOs and if they all meet the conservative criteria previously used for single MMO instructions, then return all of the underlying objects derived from the MMOs. The change to ScheduleDAGInstrs::buildSchedGraph() is needed to avoid the case where multiple underlying objects are present and are related in such a way that successive iterations of the loop end up adding a dependency from an instruction to itself.

* Record wrapping assumptions earlyJohannes Doerfert2016-04-1212-76/+53
| | | | | | | | Utilizing the record option for assumptions we can simplify the wrapping assumption generation a lot. Additionally, we can now report locations together with wrapping assumptions, though they might not be accurate yet. llvm-svn: 266069
* Record assumptions first and add them laterJohannes Doerfert2016-04-1211-20/+89
| | | | | | | | | | | | | | | | | | There are three reasons why we want to record assumptions first before we add them to the assumed/invalid context: 1) If the SCoP is not profitable or otherwise invalid without the assumed/invalid context we do not have to compute it. 2) Information about the context are gathered rather late in the SCoP construction (basically after we know all parameters), thus the user might see overly complicated assumptions to be taken while they would have been simplified later on. 3) Currently we cannot take assumptions at any point but have to wait, e.g., for the domain generation to finish. This makes wrapping assumptions much more complicated as they need to be and it will have a similar effect on "signed-unsigned" assumptions later. llvm-svn: 266068

* This reverts commit r266002, r266011 and r266016.Rafael Espindola2016-04-128-1074/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | They broke the msan bot. Original message: Add __atomic_* lowering to AtomicExpandPass. AtomicExpandPass can now lower atomic load, atomic store, atomicrmw,and cmpxchg instructions to __atomic_* library calls, when the target doesn't support atomics of a given size. This is the first step towards moving all atomic lowering from clang into llvm. When all is done, the behavior of __sync_* builtins, __atomic_* builtins, and C11 atomics will be unified. Previously LLVM would pass everything through to the ISelLowering code. There, unsupported atomic instructions would turn into __sync_* library calls. Because of that behavior, Clang currently avoids emitting llvm IR atomic instructions when this would happen, and emits __atomic_* library functions itself, in the frontend. This change makes LLVM able to emit __atomic_* libcalls, and thus will eventually allow clang to depend on LLVM to do the right thing. It is advantageous to do the new lowering to atomic libcalls in AtomicExpandPass, before ISel time, because it's important that all atomic operations for a given size either lower to __atomic_* libcalls (which may use locks), or native instructions which won't. No mixing and matching. At the moment, this code is enabled only for SPARC, as a demonstration. The next commit will expand support to all of the other targets.

'linear' '(' <linear-list> [ ':' <linear-step> ] ')' When a linear-step expression is specified in a linear clause it must be either a constant integer expression or an integer-typed parameter that is specified in a uniform clause on the directive.

* [OPENMP 4.0] Support for 'aligned' clause in 'declare simd' directive.Alexey Bataev2016-04-129-112/+266
| | | | | | | | | The aligned clause declares that the object to which each list item points is aligned to the number of bytes expressed in the optional parameter of the aligned clause. 'aligned' '(' <argument-list> [ ':' <alignment> ] ')' The optional parameter of the aligned clause, alignment, must be a constant positive integer expression. If no optional parameter is specified, implementation-defined default alignments for SIMD instructions on the target platforms are assumed. The special this pointer can be used as if was one of the arguments to the function in any of the linear, aligned, or uniform clauses. llvm-svn: 266052
