* Move constant-sized bitvector to the stack.Benjamin Kramer2014-09-111-2/+2

* Combine fmul vector FP constants when unsafe math is allowed.Sanjay Patel2014-09-112-6/+70
| | | | | | | | | | | | | | | | | | | This is an extension of the change made with r215820: http://llvm.org/viewvc/llvm-project?view=revision&revision=215820 That patch allowed combining of splatted vector FP constants that are multiplied. This patch allows combining non-uniform vector FP constants too by relaxing the check on the type of vector. Also, canonicalize a vector fmul in the same way that we already do for scalars - if only one operand of the fmul is a constant, make it operand 1. Otherwise, we miss potential folds. This fold is also done by -instcombine, but it's possible that extra fmuls may have been generated during lowering. Differential Revision: http://reviews.llvm.org/D5254 llvm-svn: 217599

* R600: Add cmpxchg instruction for evergreenAaron Watry2014-09-112-5/+29
| | | | | | | | | | | | | | | | | Refactored the R600_LDS_1A2D class a bit to get it to actually work. It seemed to be previously unused and broken. We also have to disable the conversion to the noret variant for now in R600ISelLowering because the getLDSNoRetOp method only handles 1A1D LDS ops. Someone can feel free to modify the AMDGPU::getLDSNoRetOp method to work for more than 1A1D variants of LDS operations. It's being left as a future TODO for now.

| | | | | | | | | | | David Blaikie's commits r217563 & r217564, which added shared_ptr to the CostPool have fixed some memory leak issues exposed by the PBQP with coalescing constraints. The sanitizer bot was failing because of those leaks. Now that the leaks are gone, we can reenable the aarch64/pbqp test. llvm-svn: 217580

* shared_ptrify ownershp of PoolEntries in PBQP's CostPoolDavid Blaikie2014-09-101-46/+10
| | | | | | | | | | | | | | Leveraging both intrusive shared_ptr-ing (std::enable_shared_from_this) and shared_ptr<T>-owning-U (to allow external users to hold std::shared_ptr<CostT> while keeping the underlying PoolEntry alive). The intrusiveness could be removed if we had a weak_set that implicitly removed items from the set when their underlying data went away. This /might/ fix an existing memory leak reported by LeakSanitizer in r217504. llvm-svn: 217563

| | | | | | | | | | | | | With this a DataLayoutPass can be reused for multiple modules. Once we have doInitialization/doFinalization, it doesn't seem necessary to pass a Module to the constructor. Overall this change seems in line with the idea of making DataLayout a required part of Module. With it the only way of having a DataLayout used is to add it to the Module. llvm-svn: 217548

* [AlignmentFromAssumptions] Don't divide by zero for unknown starting alignmentHal Finkel2014-09-102-2/+158
| | | | | | | | | | The routine that determines an alignment given some SCEV returns zero if the answer is unknown. In a case where we could determine the increment of an AddRec but not the starting alignment, we would compute the integer modulus by zero (which is illegal and traps). Prevent this by returning early if either the start or increment alignment is unknown (zero). llvm-svn: 217544

| | | | | | | | | | | | | | | | | | | | Summary: Make CallingConv::ID a plain unsigned instead of enum with a fixed set of valus. LLVM IR allows arbitraty calling conventions (you are free to write cc12345), and loading them as enum is an undefined behavior. This was reported by UBSan.
