2015-03-10[AArch64] Avoid going through GPRs for across-vector instructions.Ahmed Bougacha8-124/+611
This adds new node types for each intrinsic. For instance, for addv, we have AArch64ISD::UADDV, such that: (v4i32 (uaddv ...)) is the same as (v4i32 (scalar_to_vector (i32 (int_aarch64_neon_uaddv ...)))) that is, (v4i32 (INSERT_SUBREG (v4i32 (IMPLICIT_DEF)), (i32 (int_aarch64_neon_uaddv ...)), ssub) In a combine, we transform all such across-vector-lanes intrinsics to: (i32 (extract_vector_elt (uaddv ...), 0)) This has one big advantage: by making the extract_element explicit, we enable the existing patterns for lane-aware instructions to fire. This lets us avoid needlessly going through the GPRs. Consider: uint32x4_t test_mul(uint32x4_t a, uint32x4_t b) { return vmulq_n_u32(a, vaddvq_u32(b)); } We now generate: addv.4s s1, v1 mul.4s v0, v0, v1[0] instead of the previous: addv.4s s1, v1 fmov w8, s1 dup.4s v1, w8 mul.4s v0, v1, v0 rdar://20044838 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231840 91177308-0d34-0410-b5e6-96231b3b80d8
2015-03-10[AArch64] Remove integer INSvi*lane patterns. NFCI.Ahmed Bougacha1-4/+0
Most are redundant, and they never seem to fire. The V128 integer patterns already exist in the INS multiclass. The duplicates only fire when the vector index type isn't i64, because they accept "imm" instead of an explicit "i64", as the instruction definition patterns do. TLI::getVectorIdxTy is i64 on AArch64, so this should never happen. Also, one of them had a typo: for i64, INSvi32lane was used. I noticed because I mistakenly used an explicit i32 as the idx type, and got ins.s for an i64 vector_insert. The V64 patterns also don't seem to ever fire, as V64 vector extract/insert are legalized to V128. The equivalent float patterns are unique and useful, so keep them. No functional change intended; none exhibited on the LIT and LNT tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231838 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-10[LAA-memchecks 3/3] Introduce pointer partitions for memchecksAdam Nemet2-13/+65
This is the final patch that actually introduces the new parameter of partition mapping to RuntimePointerCheck::needsChecking. Another API (LAI::getInstructionsForAccess) is also exposed that helps to map pointers to instructions because ultimately we partition instructions. The WIP version of the Loop Distribution pass in D6930 has been adapted to use all this. See for example, how InstrPartitionContainer::computePartitionSetForPointers sets up the partitions using the above API and then calls to LAI::addRuntimeCheck with the pointer partitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231818 91177308-0d34-0410-b5e6-96231b3b80d8
2015-03-10[LAA-memchecks 2/3] Move number of memcheck threshold checking to LVAdam Nemet3-28/+24
Now the analysis won't "fail" if the memchecks exceed the threshold. It is the transform pass' responsibility to perform the check. This allows the transform pass to further analyze/eliminate the memchecks. E.g. in Loop distribution we only need to check pointers that end up in different partitions. Note that there is a slight change of functionality here. The logic in analyzeLoop is that if dependence checking fails due to non-constant distance between the pointers, another attempt is made to prove safety of the dependences purely using run-time checks. Before this patch we could fail the loop due to exceeding the memcheck threshold after the first step, now we only check the threshold in the client after the full analysis. There is no measurable compile-time effect but I wanted to record this here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231817 91177308-0d34-0410-b5e6-96231b3b80d8
2015-03-10[LAA-memchecks 1/3] Split out NumComparisons checks. NFCAdam Nemet1-22/+30
The check for the number of memchecks will be moved to the client of this analysis. Besides allowing for transform-specific thresholds, this also lets Loop Distribution post-process the memchecks; Loop Distribution only needs memchecks between pointers of different partitions. The motivation for this first patch is to untangle the CanDoRT check from the NumComparison check before moving the NumComparison part. CanDoRT means that we couldn't determine the bounds for the pointer. Note that NumComparison is set independent of this flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231816 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-10[LoopAccesses 2/3] Allow querying of interesting dependencesAdam Nemet2-24/+178
Gather an array of interesting dependences rather than just failing after the first unsafe one and regarding the loop unsafe. Loop Distribution needs to be able to collect all dependences in order to isolate the dependence cycles into their own partition. Since the dependence checking algorithm is quadratic in terms of accesses sharing the same underlying pointer, I am applying a cut-off threshold (MaxInterestingDependence). Exceeding that, the logic reverts back to the original approach deeming the loop unsafe upon encountering the first unsafe dependence. The main idea of the patch is to split isDepedent from directly answering the question whether the dep is safe for vectorization to return a dependence type which then gets mapped to old boolean result using Dependence::isSafeForVectorization. Tested that this was compile-time neutral on SpecINT2006 LTO bitcode inputs. No assembly change on the testsuite including external. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231806 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-10[BranchFolding] Remove MMOs during tail merge to preserve dependencies.Chad Rosier3-0/+81
When tail merging it may be necessary to remove MMOs from memory operations to ensures later passes (e.g., MI sched) conservatively compute dependencies. Currently, we only remove the MMO from the common tail if the MMO doesn't match with the relative instruction in the non-common tail(s). A more robust solution would be to add multiple MMOs from the duplicate MIs to the new MI. Currently ScheduleDAGInstrs.cpp ignores all MMOs on instructions with multiple MMOs, so this solution is equivalent for the time being. No test case included as this is incredibly difficult to reproduce. Patch was a collaborative effort between Ana Pazos and myself.
