* 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

* Copy data files to the remote runner.Dan Albert2015-03-102-18/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The data files for any given test will be in the same directory as the source with a file name that matches *.dat. To make these available to tests running remotely (such as over adb or ssh), copy them into the test's remote working directory. Note that we will perform more copies than we actually need. The data files in the directory may only be used by one of the tests, but will be copied for all tests in the same directory. This patch also moves the remote test binary into the working directory (previously it was only invoked from the working directory rather than existing in it).

* [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

* [AArch64] Remove integer INSvi*lane patterns. NFCI.Ahmed Bougacha2015-03-101-4/+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. llvm-svn: 231838
