* Holding my nose and moving the accumulation routine to GEPOperatorChandler Carruth2012-12-111-28/+2
| | | | | | | | | | | | | | | | | instead of the instruction. I've left a forwarding wrapper for the instruction so users with the instruction don't need to create a GEPOperator themselves. This lets us remove the copy of this code in instsimplify. I've looked at most of the other copies of similar code, and this is the only one I've found that is actually exactly the same. The one in InlineCost is very close, but it requires re-mapping non-constant indices through the cost analysis value simplification map. I could add direct support for this to the generic routine, but it seems overly specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169853 91177308-0d34-0410-b5e6-96231b3b80d8

* Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling2012-12-042-4/+6
| | | | | | | | | | The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169312 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a 'count' field to the DWARF subrange.Bill Wendling2012-12-041-2/+4
| | | | | | | | | | The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169218 91177308-0d34-0410-b5e6-96231b3b80d8

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-0332-109/+112
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a PassManager pointer use-after-free bug.Zhou Sheng2012-11-261-0/+12
| | | | | | | The bug can be triggered when we require LoopInfo analysis ahead of DominatorTree construction in a Module Pass. The cause is that the LoopInfo analysis itself also invokes DominatorTree construction, therefore, when PassManager schedules LoopInfo, it will add DominatorTree first. Then after that, when the PassManger turns to schedule DominatorTree invoked by the above ModulePass, it finds there is already a DominatorTree, so it delete the redundant one. However, somehow it still try to access that pass pointer after free as code pasted below, which results in segment fault. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168581 91177308-0d34-0410-b5e6-96231b3b80d8

* Make GlobalOpt be conservative with TLS variables (PR14309)Hans Wennborg2012-11-151-0/+25
| | | | | | | | | | | | | | For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168037 91177308-0d34-0410-b5e6-96231b3b80d8

* Relax the restrictions on vector of pointer types, and vector getelementptr.Duncan Sands2012-11-134-47/+74
| | | | | | | | | | | | | | | | Previously in a vector of pointers, the pointer couldn't be any pointer type, it had to be a pointer to an integer or floating point type. This is a hassle for dragonegg because the GCC vectorizer happily produces vectors of pointers where the pointer is a pointer to a struct or whatever. Vector getelementptr was restricted to just one index, but now that vectors of pointers can have any pointer type it is more natural to allow arbitrary vector getelementptrs. There is however the issue of struct GEPs, where if each lane chose different struct fields then from that point on each lane will be working down into unrelated types. This seems like too much pain for too little gain, so when you have a vector struct index all the elements are required to be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167828 91177308-0d34-0410-b5e6-96231b3b80d8
