* 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

* Let OnDiskHashTable call the destructor of its Items.Nico Weber2014-05-07
| | | | | | | | | | | | | OnDiskHashTable::insert() calls the Item constructor via placement new, but nothing called the destructor. This matters in cases when the Info template parameter has key_type or data_type typedefs that have a destructor, for example like IdentifierIndexWriterTrait in clang's GlobalModuleIndex.cpp. This fixes a 5-year old bug that's been around since the OnDiskHashTable code was added in r64192. Bug found by LSan! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208243 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix using wrong result type for setcc.Matt Arsenault2014-05-07
| | | | | | | | | | | When reducing the bitwidth of a comparison against a constant, the original setcc's result type was used, which was incorrect. No test since I don't think any other in tree targets change the bitwidth of the setcc type depending on the bitwidth of the compared type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208236 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

* [tablegen] Add !listconcat operator with the similar semantics as !strconcatDaniel Sanders2014-05-07
| | | | | | | | | | | | | | | | | | | | Summary: It concatenates two or more lists. In addition to the !strconcat semantics the lists must have the same element type. My overall aim is to make it easy to append to Instruction.Predicates rather than override it. This can be done by concatenating lists passed as arguments, or by concatenating lists passed in additional fields.

* llvm-cov: Handle missing source files as GCOV doesJustin Bogner2014-05-07
| | | | | | | | | | | If the source files referenced by a gcno file are missing, gcov outputs a coverage file where every line is simply /*EOF*/.

| | | | | | | | | | | This patch implements the infrastructure to use named register constructs in programs that need access to specific registers (bare metal, kernels, etc).

* Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k ↵Nick Lewycky2014-05-05
| | | | | | | | | | | calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'. The number of tail call to loop conversions remains the same (1618 by my count). The new algorithm does a local scan over the use-def chains to identify local "alloca-derived" values, as well as points where the alloca could escape. Then, a visit over the CFG marks blocks as being before or after the allocas have escaped, and annotates the calls accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208017 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | This moves most of GlobalOpt's constructor optimization code out of GlobalOpt into Transforms/Utils/CDtorUtils.{h,cpp}. The public interface is a single function OptimizeGlobalCtorsList() that takes a predicate returning which constructors to remove. GlobalOpt calls this with a function that statically evaluates all constructors, just like it did before. This part of the change is behavior-preserving. Also add a call to this from GlobalDCE with a filter that removes global constructors that contain a "ret" instruction and nothing else – this fixes PR19590. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207856 91177308-0d34-0410-b5e6-96231b3b80d8
