2009-02-20Just roll back the previous change to -mem2reg.Zhou Sheng
Will re-think about this according to Chris's comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65126 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20patch to update the line number information in pass -mem2reg.Zhou Sheng
Currently this pass will delete the variable declaration info, and keep the line number info. But the kept line number info is not updated, and some is redundant or not correct, this patch just updates those info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65123 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20Fix a crash in the pre-alloc splitter exposed by recent codegen changes.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65121 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20Add a quick pass to the stack slot colorer to eliminate some trivially ↵Owen Anderson
redundant spills after coloring. Ideally these would never get created in the first place, but until we enhance the spiller to have a more global picture of what's happening, this is necessary for code quality in some circumstances. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65120 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65117 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20Implement "superhero" strength reduction, or full strengthDan Gohman
reduction of address calculations down to basic pointer arithmetic. This is currently off by default, as it needs a few other features before it becomes generally useful. And even when enabled, full strength reduction is only performed when it doesn't increase register pressure, and when several other conditions are true. This also factors out a bunch of exisiting LSR code out of StrengthReduceStridedIVUsers into separate functions, and tidies up IV insertion. This actually decreases register pressure even in non-superhero mode. The change in iv-users-in-other-loops.ll is an example of this; there are two more adds because there are two fewer leas, and there is less spilling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65108 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19Use DEBUG() instead of passing *DOUT to WriteAsOperand,Dan Gohman

2009-02-19If an executable is run through a symlink, dladdr will return theChris Lattner
symlink. We really want the ultimate executable being run, not the symlink. This lets clang find its headers when invoked through a symlink. rdar://6602012 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65017 91177308-0d34-0410-b5e6-96231b3b80d8

here. Since we only do the transform if there is one use, strip off any such users in the hope of making the transform fire more often. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64926 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Use a sign-extend instead of a zero-extend when promoting aDan Gohman
trip count value when the original loop iteration condition is signed and the canonical induction variable won't undergo signed overflow. This isn't required for correctness; it just preserves more information about original loop iteration values. Add a getTruncateOrSignExtend method to ScalarEvolution, following getTruncateOrZeroExtend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64918 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

are multiple IV's in a loop, some of them may under go signed or unsigned wrapping even if the IV that's used in the loop exit condition doesn't. Restrict sign-extension-elimination and zero-extension-elimination to only those that operate on the original loop-controlling IV. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64866 91177308-0d34-0410-b5e6-96231b3b80d8
