* Add the "vbroadcasti128" instruction back.Juergen Ributzka2015-03-112-0/+9
| | | | | | | | | | This is a follow-up to r231182. This adds the "vbroadcasti128" instruction back, but without the intrinsic mapping. Also add a test to check the instriction encoding. This is related to rdar://problem/18742778. llvm-svn: 231945
* Make NaCl's use of .init_array for static constructors match LinuxDerek Schuff2015-03-114-6/+15
| | | | | | | | | | | | Summary: The generic ELF TargetObjectFile defaults to .ctors, but Linux's defaults to .init_array by calling InitializeELF with the value of UseInitArray from TargetMachine. Make NaCl's behavior match. Reviewers: jvoung Differential Revision: http://reviews.llvm.org/D8240 llvm-svn: 231934

* Inliner should not add callgraph edges for intrinsic calls (PR22857)Sanjay Patel2015-03-112-1/+38

| | | | | | | | As of r231908, the test I added in r231902 actually gets run - but I'd checked in a stale version of the input so it didn't pass. Fix the input and un-xfail the test. llvm-svn: 231911

In this case, we would already have reported an error on the referenced intrinsic, but then crashed on the second one when it tried to introspect the first without error checking. llvm-svn: 231910

| | | | | | | | | There were also errors in the CHECK line which I fixed and the test doesn't actually pass as the "100" is in the wrong line. Not sure whether this is a test failure or a coverage failure so making the test XFAIL for now. llvm-svn: 231908

* If a conditional branch jumps to the same target, remove the conditionPhilip Reames2015-03-102-0/+25
| | | | | | | | | | | | Given that large parts of inst combine is restricted to instructions which have one use, getting rid of a use on the condition can help the effectiveness of the optimizer. Also, it allows the condition to potentially be deleted by instcombine rather than waiting for another pass. I noticed this completely by accident in another test case. It's not anything that actually came from a real workload. p.s. We should probably do the same thing for switch instructions. Differential Revision: http://reviews.llvm.org/D8220 llvm-svn: 231881
* Emit correct linkage-name attribute based on DWARF version.Paul Robinson2015-03-1016-32/+34
| | | | | | | | | | There are still 4 tests that check for DW_AT_MIPS_linkage_name, because they specify DWARF 2 or 3 in the module metadata. So, I didn't create an explicit version-based test for the attribute. Differential Revision: http://reviews.llvm.org/D8227 llvm-svn: 231880
* Infer known bits from dominating conditionsPhilip Reames2015-03-102-0/+364
| | | | | | | | | | | | | | | | | This patch adds limited support in ValueTracking for inferring known bits of a value from conditional expressions which must be true to reach the instruction we're trying to optimize. At this time, the feature is off by default. Once landed, I'm hoping for feedback from others on both profitability and compile time impact. Forms of conditional value propagation have been tried in LLVM before and have failed due to compile time problems. In an attempt to side step that, this patch only considers conditions where the edge leaving the branch dominates the context instruction. It does not attempt full dataflow. Even with that restriction, it handles many interesting cases: * Early exits from functions * Early exits from loops (for context instructions in the loop and after the check) * Conditions which control entry into loops, including multi-version loops (such as those produced during vectorization, IRCE, loop unswitch, etc..) Possible applications include optimizing using information provided by constructs such as: preconditions, assumptions, null checks, & range checks. This patch implements two approaches to the problem that need further benchmarking. Approach 1 is to directly walk the dominator tree looking for interesting conditions. Approach 2 is to inspect other uses of the value being queried for interesting comparisons. From initial benchmarking, it appears that Approach 2 is faster than Approach 1, but this needs to be further validated. Differential Revision: http://reviews.llvm.org/D7708 llvm-svn: 231879
* Remove the use of the subtarget in MCCodeEmitter creation andEric Christopher2015-03-1026-67/+29

* Create symbols marking the start of a section earlier.Rafael Espindola2015-03-1011-126/+152
| | | | | | | | | This lets us pass the symbol to the constructor and avoid the mutable field. This also opens the way for outputting the symbol only when needed, instead of outputting them at the start of the file. llvm-svn: 231859

* [CodeGenPrepare] Refine the cost model provided by the promotion helper.Quentin Colombet2015-03-104-64/+141
| | | | | | | | | | | | | | | | | - Use TargetLowering to check for the actual cost of each extension. - Provide a factorized method to check for the cost of an extension: TargetLowering::isExtFree. - Provide a virtual method TargetLowering::isExtFreeImpl for targets to be able to tune the cost of non-free extensions. This refactoring offers a better granularity to model what really happens on different targets. No performance changes and very few code differences.

* [LoopAccesses] Add debug message to indicate the result of the analysisAdam Nemet2015-03-101-4/+7
| | | | | | | | | | The debug message was pretty confusing here. It only reported the situation with memchecks without the result of the dependence analysis. Now it prints whether the loop is safe from the POV of the dependence analysis and if yes, whether we need memchecks. llvm-svn: 231854

* [AArch64] Avoid going through GPRs for across-vector instructions.Ahmed Bougacha2015-03-108-124/+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 llvm-svn: 231840
