2009-10-29Rename usesCustomDAGSchedInserter to usesCustomInserter, and update aDan Gohman
bunch of associated comments, because it doesn't have anything to do with DAGs or scheduling. This is another step in decoupling MachineInstr emitting from scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85517 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29just for the hell of it, allow globalopt to statically evaluate Chris Lattner
static constructors with indirect gotos :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85495 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29add interpreter support for indirect goto / blockaddress. The interpreterChris Lattner
now correctly runs clang's test/CodeGen/indirect-goto.c. The JIT will abort on it until someone feels compelled to implement this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85488 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29To get more thorough testing from llc-beta nightly runs, do dynamic stackJim Grosbach
realignment regardless of whether it's strictly necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85476 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29When the function is doing dynamic stack realignment, the spill slot will beJim Grosbach
indexed via the stack pointer, even if a frame pointer is present. Update the heuristic to place it nearest the stack pointer in that case, rather than nearest the frame pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85474 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29Sorry to break the build.Johnny Chen
I was trying to check the WIP file to some local repository, but ended up checking in the llvm repository. Oops! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85470 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29When there is a 2-instruction spill sequence, recordDale Johannesen
the second (store) instruction in SpillSlotToUsesMap consistently. I don't think this matters functionally, but it's cleaner and Evan wants it this way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85463 91177308-0d34-0410-b5e6-96231b3b80d8

common tail, except when the OptimizeForSize function attribute is present. Radar 7338114. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85441 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28When we generate spill code, then decide we don't needDale Johannesen
to spill after all, we weren't handling 2-instruction spill sequences correctly (PPC Altivec). We need to remove the store in this case. Removing the other instruction(s) would be goodness but is not needed for correctness, and isn't done here. 7331562. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85437 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28Extend getMallocArraySize() to determine the array size if the malloc ↵Victor Hernandez
argument is: ArraySize * ElementSize ElementSize * ArraySize ArraySize << log2(ElementSize) ElementSize << log2(ArraySize) Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic. Update users of getMallocArraySize() to not bother calling isArrayMalloc() as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85421 91177308-0d34-0410-b5e6-96231b3b80d8
