2009-10-15Revert svn r80498 and replace it with a different solution. The only problemBob Wilson
I can see with the original code was that I forgot that this runs after type legalization and hence the result type will always be i32. (Custom legalization of EXTRACT_VECTOR_ELT is only enabled for vector types with 8- and 16-bit elements.) Regarding the FIXME comment: any information about sign and zero-extension should be captured by separate extension operations. The DAG combiner should handle those to produce either VGETLANEu or VGETLANEs, and that seems to be working now. If there are cases that we're missing, let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84218 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Fix a potential performance problem in placing ARM constant pools.Bob Wilson
In the case where there are no good places to put constants and we fall back upon inserting unconditional branches to make new blocks, allow all constant pool references in range of those blocks to put constants there, even if that means resetting the "high water marks" for those references. This will still terminate because you can't keep splitting blocks forever, and in the bad cases where we have to split blocks, it is important to avoid splitting more than necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84202 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Fix bug where array malloc with unexpected computation of the size argument ↵Victor Hernandez
resulted in MallocHelper identifying the malloc as a non-array malloc. This broke GlobalOpt's optimization of stores of mallocs to global variables. The fix is to classify malloc's into 3 categories: 1. non-array mallocs 2. array mallocs whose array size can be determined 3. mallocs that cannot be determined to be of type 1 or 2 and cannot be optimized getMallocArraySize() returns NULL for category 3, and all users of this function must avoid their malloc optimization if this function returns NULL. Eventually, currently unexpected codegen for computing the malloc's size argument will be supported in isArrayMalloc() and getMallocArraySize(), extending malloc optimizations to those examples. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84199 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Fix another problem with ARM constant pools. Radar 7303551.Bob Wilson
When ARMConstantIslandPass cannot find any good locations (i.e., "water") to place constants, it falls back to inserting unconditional branches to make a place to put them. My recent change exposed a problem in this area. We may sometimes append to the same block more than one unconditional branch. The symptoms of this are that the generated assembly has a branch to an undefined label and running llc with -debug will cause a seg fault. This happens more easily since my change to prevent CPEs from moving from lower to higher addresses as the algorithm iterates, but it could have happened before. The end of the block may be in range for various constant pool references, but the insertion point for new CPEs is not right at the end of the block -- it is at the end of the CPEs that have already been placed at the end of the block. The insertion point could be out of range. When that happens, the fallback code will always append another unconditional branch if the end of the block is in range. The fix is to only append an unconditional branch if the block does not already end with one. I also removed a check to see if the constant pool load instruction is at the end of the block, since that is redundant with checking if the end of the block is in-range. There is more to be done here, but I think this fixes the immediate problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84172 91177308-0d34-0410-b5e6-96231b3b80d8
