2008-05-16If the result of a BIT_CONVERT is a v1* vector, it doesn't mean its source ↵Evan Cheng
is a v1* vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51192 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-16Silence the compiler warning differently. TheDuncan Sands
original method caused gcc-4.2 to complain. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51186 91177308-0d34-0410-b5e6-96231b3b80d8

instruction). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51184 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-16Do not dup malloc, vector instructions, etc. Throttle the default theshold ↵Evan Cheng
way down. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51183 91177308-0d34-0410-b5e6-96231b3b80d8
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

2008-05-16Clean ups for loop deletion based on Chris' feedback.Owen Anderson
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

2008-05-16Fix this test. It was testing broken behavior in that it required ADCE to ↵Owen Anderson
eliminate a potentially infinite loop, which is undesirable. Instead, test the LICM behavior that we're really interested in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51177 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-16Revert the change from r51157 inDan Gohman
test/Verifier/2002-11-05-GetelementptrPointers.ll, which was incorrect. Instead, fix getIndexedType to not follow pointer types, as PointerType is a subclass of CompositeType. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51171 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-15Update comments based on Duncan's feedback.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51170 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
2008-05-15Remove the S92 code, which really has nothing to doDale Johannesen
with what the test is testing; makes it pass again on ppc32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51167 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-15Allow an extra bit for CommonLinkage.Dale Johannesen
This changes the .bc file format, but if I understand how it works correctly, old .bc files continue to be readable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51161 91177308-0d34-0410-b5e6-96231b3b80d8

something with a v1 type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51160 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-15Move the operator new and operator delete out of line. This fixes an issue withNate Begeman
operator new() referring to the static initTags function, which has to be in the same linkage unit as any file including User.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51136 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
