* Always create a .got on mips.Rafael Espindola2016-04-126-44/+73
| | | | | | | | | The _gp* family of symbols is defined as an offset in .got, and it is not at all clear what should happen when .got is not defined. This will allow some simplifications on how these symbols are handled. llvm-svn: 266063
* 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.

* [SystemZ] Use LDE32 instead of LE, when Offset is small.Jonas Paulsson2016-04-121-1/+7
| | | | | | | | | | | | On z13, if eliminateFrameIndex() chooses LE (and not LEY), immediately transform that LE to LDE32 to avoid partial register dependencies. LEY should be generally preferred for big offsets over an expansion into LAY + LDE32. Reviewed by Ulrich Weigand. llvm-svn: 266060

* [OPENMP 4.0] Support for 'linear' clause in 'declare simd' directive.Alexey Bataev2016-04-1210-95/+358
| | | | | | | | | | The linear clause declares one or more list items to be private to a SIMD lane and to have a linear relationship with respect to the iteration space of a loop. '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. 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: 266056

| | | | | | | | | | Collect the error domain contexts (formerly in the ErrorDomainCtxMap) for each statement in the new InvalidContext member variable. While this commit is basically a [NFC] it is a first step to make hoisting sound by allowing a more fine grained record of invalid contexts, e.g., here on statement level. llvm-svn: 266053
* [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

* Refactor the Internalize stage of libLTO in a separate file (NFC)Mehdi Amini2016-04-126-141/+232
| | | | | | | | | | | | | | | | | This is intended to be shared by the ThinLTOCodeGenerator. Note that there is a change in the way the verifier is run, previously it was ran as a Pass on the merged module during internalization. While now the verifier is called explicitely on the merged module outside of the internalize "pass pipeline". What remains strange in the API is the fact that `DisableVerify` in the API does not disable this initial verifier.

If only one nonvolatile CR field is clobbered, use mfocrf instead of mfcr to selectively save the field, because mfocrf has short latency compares to mfcr. Thanks Nemanja's invaluable hint!

* Add the allocsize attribute to LLVM.George Burgess IV2016-04-1220-71/+577
| | | | | | | | | | | | | | | | `allocsize` is a function attribute that allows users to request that LLVM treat arbitrary functions as allocation functions. This patch makes LLVM accept the `allocsize` attribute, and makes `@llvm.objectsize` recognize said attribute. The review for this was split into two patches for ease of reviewing: D18974 and D14933. As promised on the revisions, I'm landing both patches as a single commit. Differential Revision: http://reviews.llvm.org/D14933 llvm-svn: 266032
