* Added basic unit test for llvm-cov.Yuchen Wu2013-11-057-0/+169
| | | | | | | This test compares the output of llvm-cov against a coverage file generated by gcov. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194038 91177308-0d34-0410-b5e6-96231b3b80d8

* AArch64: use default asm operand printing when modifier inapplicableTim Northover2013-11-041-0/+29
| | | | | | | | | | | | If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate or register) and an operand modifier (E.g. "w" for "print register as wN") then we need to decide behaviour when the modifier doesn't apply to the constraint. Previousely produced some combination of an assertion failure and a fatal error. GCC's behaviour appears to be to ignore the modifier and print the operand in the default way. This patch should implement that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194024 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | In order to create an ObjectFile implementation that uses bitcode files, we need to propagate the bitcode errors to the ObjectFile interface, so we need to convert it to use the same error handling as ObjectFile: error_code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193996 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: regenerate test case from Clang to adjust for fixes/improvementsDavid Blaikie2013-11-011-87/+64
| | | | | | | | | | | I hit some problems with future work due to the member subprogram of 'a_b's type having a subprogram (an implicit default ctor, !52 in the pre-commit source) with no name. Clang now generates a name for such a function but in this case doesn't even emit debug info for it as it is unused (Clang never emits the body of the ctor, instead just emitting memset if needed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193892 91177308-0d34-0410-b5e6-96231b3b80d8
* LoopVectorizer: Perform redundancy elimination on induction variablesArnold Schwaighofer2013-11-013-5/+42
| | | | | | | | | | | | | | | | | | | | When the loop vectorizer was part of the SCC inliner pass manager gvn would run after the loop vectorizer followed by instcombine. This way redundancy (multiple uses) were removed and instcombine could perform scalarization on the induction variables. Having moved the loop vectorizer to later we no longer run any form of redundancy elimination before we perform instcombine. This caused vectorized induction variables to survive that did not before. On a recent iMac this helps linpack back from 6000Mflops to 7000Mflops. This should also help lpbench and paq8p. I ran a Release (without Asserts) build over the test-suite and did not see any negative impact on compile time. radar://15339680 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193891 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Make pubnames header printing similar to unit header printingDavid Blaikie2013-11-013-14/+4
| | | | | | | | | | | | | | | In a failed attempt to allow the gnu-public-names.ll test case to not hardcode the size of the unit that the pubnames section referred to I've at least managed to have unit headers and pubnames headers print out in a similar style. This failed to achieve the desired goal because the header in a unit specifies the length of the unit without the length element of the header whereas the length in the pubnames includes this element, so the numbers are off by 4 bytes. I don't know of any arithmetic powers in FileCheck so the test case can't simply say "CU_LENGTH + 4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193872 91177308-0d34-0410-b5e6-96231b3b80d8

* [ARM] Add Virtualization subtarget feature and more build attributes in this ↵Bradley Smith2013-11-013-264/+128
| | | | | | | | | | | | | | | | | area Add a Virtualization ARM subtarget feature along with adding proper build attribute emission for Tag_Virtualization_use (encodes Virtualization and TrustZone) and Tag_MPextension_use. Also rework test/CodeGen/ARM/2010-10-19-mc-elf-objheader.ll testcase to something that is more maintainable. This changes the focus of this testcase away from testing CPU defaults (which is tested elsewhere), onto specifically testing that attributes are encoded correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193859 91177308-0d34-0410-b5e6-96231b3b80d8

* Consider (x == -1) unlikely in BranchProbabilityInfoHal Finkel2013-11-011-0/+39
| | | | | | | | | | | | This adds another heuristic to BPI, similar to the existing heuristic that considers (x == 0) unlikely to be true. As suggested in the PACT'98 paper by Deitrich, Cheng, and Hwu, -1 is often used to indicate an invalid index, and equality comparisons with -1 are also unlikely to succeed. Local experimentation supports this hypothesis: This yields a 1-2% speedup in the test-suite sqlite benchmark on the PPC A2 core, with no significant regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193855 91177308-0d34-0410-b5e6-96231b3b80d8
* LoopVectorizer: If dependency checks fail try runtime checksArnold Schwaighofer2013-11-011-0/+28
| | | | | | | | | | | | When a dependence check fails we can still try to vectorize loops with runtime array bounds checks. This helps linpack to vectorize a loop in dgefa.
