2008-05-16Remove ADCE's ability to delete loops. This ability is now implemented in aOwen Anderson
safer manner by loop deletion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51182 91177308-0d34-0410-b5e6-96231b3b80d8

Also, use SCEV to determine the trip count of the loop, which is more powerful and accurate that Loop::getTripCount. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51179 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-15Fix a bug in LoopStrengthReduce that caused it to emit IR withDan Gohman
use-before-def. The problem comes up in code with multiple PHIs where one PHI is being rewritten in terms of the other, but the other needs to be casted first. LLVM rules requre the cast instruction to be inserted after any PHI instructions, but when instructions were inserted to replace the second PHI value with a function of the first, they were ended up going before the cast instruction. Avoid this problem by remembering the location of the cast instruction, when one is needed, and inserting the expansion of the new value after it. This fixes a bug that surfaced in 255.vortex on x86-64 when instcombine was removed from the middle of the loop optimization passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51169 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-14Situations can arise when you have a function called that returns a 'void', butBill Wendling
is bitcast to return a floating point value. The result of the instruction may not be used by the program afterwards, and LLVM will happily remove all instructions except the call. But, on some platforms, if a value is returned as a floating point, it may need to be removed from the stack (like x87). Thus, we can't get rid of the bitcast even if there isn't a use of the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51134 91177308-0d34-0410-b5e6-96231b3b80d8

bug as well as a missed optimization. We weren't properly checking for local dependencies before moving on to non-local ones when doing non-local read-only call CSE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51082 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-13Change class' public PassInfo variables to by initialized with theDan Gohman
address of the PassInfo directly instead of calling getPassInfo. This eliminates a bunch of dynamic initializations of static data. Also, fold RegisterPassBase into PassInfo, make a bunch of its data members const, and rearrange some code to initialize data members in constructors instead of using setter member functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51022 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-11Fix various DOUTs to not call the extremely expensive Value::getName() Chris Lattner
method. DOUT statements are disabled when assertions are off, but the side effects of getName() are still evaluated. Just call getNameSTart, which is close enough and doesn't cause heap traffic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50958 91177308-0d34-0410-b5e6-96231b3b80d8
