2009-09-03Disable some parts of the profiling-tool-chain test, which is currently failingDaniel Dunbar
on a self-hosted build (although it seems to work on non-self hosted). I'll work with Andreas to figure this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80947 91177308-0d34-0410-b5e6-96231b3b80d8

(See http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090831/086214.html) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80799 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Changed profiling-tool-chain.ll test to use optimal-edge-profiling instead ofAndreas Neustifter
edge-profiling, this is more useful since the loading of the optimal-edge-profiling is more complicated. The edge-profiling is tested in edge-profiling.ll where only the instrumentation is tested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80791 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Don't force the triple or data layout in this test. We just have to get themDaniel Dunbar
from the host and hope that works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80751 91177308-0d34-0410-b5e6-96231b3b80d8

make check in a non-clean directory causes it to fail (for example when running make check twice), since execution counts will differ. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80362 91177308-0d34-0410-b5e6-96231b3b80d8

error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80357 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26Create a ScalarEvolution-based AliasAnalysis implementation.Dan Gohman
This is a simple AliasAnalysis implementation which works by making ScalarEvolution queries. ScalarEvolution has a more complete understanding of arithmetic than BasicAA's collection of ad-hoc checks, so it handles some cases that BasicAA misses, for example p[i] and p[i+1] within the same iteration of a loop. This is currently experimental. It may be that the main use for this pass will be to help find cases where BasicAA can be profitably extended, or to help in the development of the overall AliasAnalysis infrastructure, however it's also possible that it could grow up to become a directly useful pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80098 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-27Change the assembly syntax for nsw, nuw, and exact, putting themDan Gohman
after their associated opcodes rather than before. This makes them a little easier to read. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77194 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25When attempting to sign-extend an addrec by interpretingDan Gohman
the step value as unsigned, the start value and the addrec itself still need to be treated as signed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77078 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-21Replace the original ad-hoc code for determining whether (v pred w) impliesDan Gohman
(x pred y) with more thorough code that does more complete canonicalization before resorting to range checks. This helps it find more cases where the canonicalized expressions match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76671 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76526 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Introduce a pointertracking pass.Torok Edwin
For now this only computes the allocated size of the memory pointed to by a pointer, and offset a pointer from allocated pointer. The actual checkLimits part will come later, after another round of review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75657 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-04When comparing constants, consider a less wide constant to be "less complex"Nick Lewycky
than a wider one, before trying to compare their contents which will crash if their sizes are different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74792 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-24Add a testcase demoing some of ScalarEvolution's new trip count logic.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74049 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Fix a bug in the trip-count computation with And/Or. If either of theDan Gohman
sides is CouldNotCompute, the resulting exact count must be CouldNotCompute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73920 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Fix llvm::ComputeNumSignBits to handle pointer typesDan Gohman
conservatively correctly, instead of aborting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73908 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Teach ScalarEvolution how to analyze loops with multiple exitDan Gohman
blocks, and also exit blocks with multiple conditions (combined with (bitwise) ands and ors). It's often infeasible to compute an exact trip count in such cases, but a useful upper bound can often be found. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73866 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-21Fix ScalarEvolution's backedge-taken count computations to check forDan Gohman
overflow when computing a integer division to round up. Thanks to Nick Lewycky for noticing this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18Teach ScalarEvolution how to recognize another xor(and(x, C), C) case.Dan Gohman
If C is a single bit and the and gets analyzed as a truncate and zero-extend, the xor can be represnted as an add. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73664 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-17Add -disable-output to a bunch of tests that don't care about the output.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73633 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-17Fix ScalarEvolution's Xor handling to not assume that an AndDan Gohman
that gets recognized with a SCEVZeroExtendExpr must be an And with a low-bits mask. With r73540, this is no longer the case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73594 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8
