* Split GlobalValue into GlobalValue and GlobalObject.Rafael Espindola2014-05-13
| | | | | | | | | This allows code to statically accept a Function or a GlobalVariable, but not an alias. This is already a cleanup by itself IMHO, but the main reason for it is that it gives a lot more confidence that the refactoring to fix the design of GlobalAlias is correct. That will be a followup patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208716 91177308-0d34-0410-b5e6-96231b3b80d8

* AVX-512: changes in intrinsicsElena Demikhovsky2014-05-12
| | | | | | | | | | | 1) Changed gather and scatter intrinsics. Now they are aligned with GCC built-ins. There is no more non-masked form. Masked intrinsic receives -1 if all lanes are executed. 2) I changed the function that works with intrinsics inside X86ISelLowering.cpp. I put all intrinsics in one table. I did it for INTRINSICS_W_CHAIN and plan to put all intrinsics from WO_CHAIN set to the same table in order to avoid the long-long "switch". (I wanted to use static map initialization that allowed by C++11 but I wasn't able to compile it on VS2012). 3) I added gather/scatter prefetch intrinsics. 4) I fixed MRMm encoding for masked instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208522 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "[ms-cxxabi] Add a new calling convention that swaps 'this' and 'sret'"Reid Kleckner2014-05-09
| | | | | | | | | | | | | | This reverts commit r200561. This calling convention was an attempt to match the MSVC C++ ABI for methods that return structures by value. This solution didn't scale, because it would have required splitting every CC available on Windows into two: one for methods and one for free functions. Now that we can put sret on the second arg (r208453), and Clang does that (r208458), revert this hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208459 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow sret on the second parameter as well as the firstReid Kleckner2014-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | MSVC always places the implicit sret parameter after the implicit this parameter of instance methods. We used to handle this for x86_thiscallcc by allocating the sret parameter on the stack and leaving the this pointer in ecx, but that doesn't handle alternative calling conventions like cdecl, stdcall, fastcall, or the win64 convention. Instead, change the verifier to allow sret on the second parameter. This also requires changing the Mips and X86 backends to return the argument with the sret parameter, instead of assuming that the sret parameter comes first. The Sparc backend also returns sret parameters in a register, but I wasn't able to update it to handle secondary sret parameters. It currently calls report_fatal_error if you feed it an sret in the second parameter.

* Move late partial-unrolling thresholds into the processor definitionsHal Finkel2014-05-08
| | | | | | | | | | | | | | | | | | | | | | The old method used by X86TTI to determine partial-unrolling thresholds was messy (because it worked by testing target features), and also would not correctly identify the target CPU if certain target features were disabled. After some discussions on IRC with Chandler et al., it was decided that the processor scheduling models were the right containers for this information (because it is often tied to special uop dispatch-buffer sizes). This does represent a small functionality change: - For generic x86-64 (which uses the SB model and, thus, will get some unrolling). - For AMD cores (because they still currently use the SB scheduling model) - For Haswell (based on benchmarking by Louis Gerbarg, it was decided to bump the default threshold to 50; we're working on a test case for this). Otherwise, nothing has changed for any other targets. The logic, however, has been moved into BasicTTI, so other targets may now also opt-in to this functionality simply by setting LoopMicroOpBufferSize in their processor model definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208289 91177308-0d34-0410-b5e6-96231b3b80d8

* split delinearization pass in 3 stepsSebastian Pop2014-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To compute the dimensions of the array in a unique way, we split the delinearization analysis in three steps: - find parametric terms in all memory access functions - compute the array dimensions from the set of terms - compute the delinearized access functions for each dimension The first step is executed on all the memory access functions such that we gather all the patterns in which an array is accessed. The second step reduces all this information in a unique description of the sizes of the array. The third step is delinearizing each memory access function following the common description of the shape of the array computed in step 2. This rewrite of the delinearization pass also solves a problem we had with the previous implementation: because the previous algorithm was by induction on the structure of the SCEV, it would not correctly recognize the shape of the array when the memory access was not following the nesting of the loops: for example, see polly/test/ScopInfo/multidim_only_ivs_3d_reverse.ll ; void foo(long n, long m, long o, double A[n][m][o]) { ; ; for (long i = 0; i < n; i++) ; for (long j = 0; j < m; j++) ; for (long k = 0; k < o; k++) ; A[i][k][j] = 1.0; Starting with this patch we no longer delinearize access functions that do not contain parameters, for example in test/Analysis/DependenceAnalysis/GCD.ll ;; for (long int i = 0; i < 100; i++) ;; for (long int j = 0; j < 100; j++) { ;; A[2*i - 4*j] = i; ;; *B++ = A[6*i + 8*j]; these accesses will not be delinearized as the upper bound of the loops are constants, and their access functions do not contain SCEVUnknown parameters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208232 91177308-0d34-0410-b5e6-96231b3b80d8
