2010-11-18Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola
and testing is easier. A good example is the unknown-location.ll test that now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for every address change anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119613 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-18Do not throw away alignment when generating the DAG forDale Johannesen
memset; we may need it to decide between MOVAPS and MOVUPS later. Adjust a test that was looking for wrong code. PR 3866 / 8675131. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119605 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Clean up LEApcrel instuction(s) a bit. It's not really a Pseudo, so don't markJim Grosbach
it as such. Add some encoding information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119588 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Factor out the code for purging a SCEV from all the various memoization maps.Dan Gohman
Some of these maps may merge in the future, but for now it's convenient to have a utility function for them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119587 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Change ARMGlobalMerge to keep BSS globals in separate pools.Bob Wilson
This completes the fixes for Radar 8673120. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119566 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Fix ARMGlobalMerge pass to check if globals are entirely within range.Bob Wilson
It is generally not sufficient to check if the starting offset is in range of the maximum offset that can be efficiently used for the target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119565 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Change the symbol for merged globals from "merged" to "_MergedGlobals".Bob Wilson
This makes it more clear that the symbol is an internal, compiler-generated name and gives a little more description about its contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119564 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes.Bob Wilson
It was mistakenly looking at the pointer type when checking for the size of global variables. This is a partial fix for Radar 8673120. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119563 91177308-0d34-0410-b5e6-96231b3b80d8

in the MC lowering process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119559 91177308-0d34-0410-b5e6-96231b3b80d8

in a register. These immediates aren't free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119558 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Reference ScalarEvolution by name rather than directly in LICM,Dan Gohman
to avoid an unneeded dependence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119557 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Before replacing a phi node with a different value, itDuncan Sands
needs to be checked that this won't break LCSSA form. Change the existing checking method to a more direct one: rather than seeing if all predecessors belong to the loop, check that the replacing value is either not in any loop or is in a loop that contains the phi node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119556 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Fix ScalarEvolution's range memoization to avoid using aDan Gohman
default ctor with ConstantRange. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119550 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Remove ARM isel hacks that fold large immediates into a pair of add, sub, and,Evan Cheng
and xor. The 32-bit move immediates can be hoisted out of loops by machine LICM but the isel hacks were preventing them. Instead, let peephole optimization pass recognize registers that are defined by immediates and the ARM target hook will fold the immediates in. Other changes include 1) do not fold and / xor into cmp to isel TST / TEQ instructions if there are multiple uses. This happens when the 'and' is live out, machine sink would have sinked the computation and that ends up pessimizing code. The peephole pass would recognize situations where the 'and' can be toggled to define CPSR and eliminate the comparison anyway. 2) Move peephole pass to after machine LICM, sink, and CSE to avoid blocking important optimizations. rdar://8663787, rdar://8241368 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119548 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Move some those Xor simplifications which don't require creating newDuncan Sands
instructions out of InstCombine and into InstructionSimplify. While there, introduce an m_AllOnes pattern to simplify matching with integers and vectors with all bits equal to one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119536 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17MC-JIT: Stub out "pure" streamer.Daniel Dunbar

2010-11-17Have InlineFunction use SimplifyInstruction rather thanDuncan Sands
hasConstantValue. I was leery of using SimplifyInstruction while the IR was still in a half-baked state, which is the reason for delaying the simplification until the IR is fully cooked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119494 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-17Now that hasConstantValue has been made simpler, it may return theDuncan Sands
phi node itself if it occurs in an unreachable basic block. Protect against this. Hopefully this will fix some more buildbots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119493 91177308-0d34-0410-b5e6-96231b3b80d8
