* [X86] Decode MPX BND registers.Ahmed Bougacha2016-07-143-15/+29
| | | | | | | | | | | | | We were able to assemble, but not disassemble. Note that fixupRMValue was truncating EA_REG_BND0-3 because we hit the uint8_t max. The control registers were already squarely above it, but I don't think they ever go in .r/m, only in .reg. I also did notice an extra REX.W in our encoding, but I think that's fine. llvm-svn: 275427
* [X86] Don't mark addressing mode operands as "outs". NFC-ish.Ahmed Bougacha2016-07-141-12/+12

* [LV] Avoid unnecessary IV scalar-to-vector-to-scalar conversionsMatthew Simpson2016-07-143-69/+118
| | | | | | | | | | | | This patch prevents increases in the number of instructions, pre-instcombine, due to induction variable scalarization. An increase in instructions can lead to an increase in the compile-time required to simplify the induction variables. We now maintain a new map for scalarized induction variables to prevent us from converting between the scalar and vector forms. This patch should resolve compile-time regressions seen after r274627. llvm-svn: 275419
* GPGPU: Use a tile size of 32 by defaultTobias Grosser2016-07-142-6/+7
| | | | | | | | | The tile size was previously uninitialized. As a result, it was often zero (aka. no tiling), which is not what we want in general. More importantly, there was the risk for arbitrary tile sizes to be choosen, which we did not observe, but which still is highly problematic. llvm-svn: 275418
* Diagnose taking address and reference binding of packed membersRoger Ferrer Ibanez2016-07-1410-1/+474
| | | | | | | | | | | | | | | | | | | | | | | This patch implements PR#22821. Taking the address of a packed member is dangerous since the reduced alignment of the pointee is lost. This can lead to memory alignment faults in some architectures if the pointer value is dereferenced. This change adds a new warning to clang emitted when taking the address of a packed member. A packed member is either a field/data member declared as attribute((packed)) or belonging to a struct/class declared as such. The associated flag is -Waddress-of-packed-member. Conversions (either implicit or via a valid casting) to pointer types with lower or equal alignment requirements (e.g. void* or char*) silence the warning. This change also adds a new error diagnostic when the user attempts to bind a reference to a packed member, regardless of the alignment.

* [OpenCL] Actually activate Frontend/opencl.cl test and fix test bugsBenjamin Kramer2016-07-142-4/+4
| | | | | | | | | | | | | | rL275318 added the test Frontend/opencl.cl test, but that test was never actually run because Frontend/lit.local.cfg doesn't contain the '.cl' file suffix. Once the test is activated, it fails with (unintended) compile errors in the newly added CHECK_INVALID_OPENCL_VERSION checks. This patch adds the '.cl' file suffix to Frontend/lit.local.cfg to activate the test and fixes the test bug by adding '-fblocks' to the relevant command lines. Patch by Martin Böhme!

* GPGPU: compute new schedule from polly scopTobias Grosser2016-07-146-17/+164
| | | | | | | | | | | | | | | | | | | | To do so we copy the necessary information to compute an initial schedule from polly::Scop to ppcg's scop. Most of the necessary information is directly available and only needs to be passed on to ppcg, with the exception of 'tagged' access relations, access relations that additionally carry information about which memory access an access relation originates from. We could possibly perform the construction of tagged accesses as part of ScopInfo, but as this format is currently specific to ppcg we do not do this yet, but keep this functionality local to our GPU code generation. After the scop has been initialized, we compute data dependences and ask ppcg to compute an initial schedule. Some of this functionality is already available in polly::DependenceInfo and polly::ScheduleOptimizer, but to keep differences to ppcg small we use ppcg's functionality here. We may later investiage if a closer integration of these tools makes sense. llvm-svn: 275390
* GPGPU: create default initialized PPCG scop and gpu programTobias Grosser2016-07-146-3/+214
| | | | | | | | | | | | | | At this stage, we do not yet modify the IR but just generate a default initialized ppcg_scop and gpu_prog and free both immediately. Both will later be filled with data from the polly::Scop and are needed to use PPCG for GPU schedule generation. This commit does not yet perform any GPU code generation, but ensures that the basic infrastructure has been put in place. We also add a simple test case to ensure the new code is run and use this opportunity to verify that GPU_CODEGEN tests are only run if GPU code generation has been enabled in cmake. llvm-svn: 275389

* This implements a more optimal algorithm for selecting a base constant inSjoerd Meijer2016-07-148-7/+186
| | | | | | | | | | | | | | constant hoisting. It not only takes into account the number of uses and the cost of expressions in which constants appear, but now also the resulting integer range of the offsets. Thus, the algorithm maximizes the number of uses within an integer range that will enable more efficient code generation. On ARM, for example, this will enable code size optimisations because less negative offsets will be created. Negative offsets/immediates are not supported by Thumb1 thus preventing more compact instruction encoding. Differential Revision: http://reviews.llvm.org/D21183 llvm-svn: 275382
