| * Change how PHINodes store their operands.Jay Foad2011-06-205-29/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change PHINodes to store simple pointers to their incoming basic blocks, instead of full-blown Uses. Note that this loses an optimization in SplitCriticalEdge(), because we can no longer walk the use list of a BasicBlock to find phi nodes. See the comment I removed starting "However, the foreach loop is slow for blocks with lots of predecessors". Extend replaceAllUsesWith() on a BasicBlock to also update any phi nodes in the block's successors. This mimics what would have happened when PHINodes were proper Users of their incoming blocks. (Note that this only works if OldBB->replaceAllUsesWith(NewBB) is called when OldBB still has a terminator instruction, so it still has some successors.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133435 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | I don't think the AugmentedUse struct buys us much, either in correctness or in ease of use. Ditch it, and simplify Use::getUser() and User::allocHungoffUses(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133433 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | all over the place in different styles and variants. Standardize on two preferred entrypoints: one that takes a StructType and ArrayRef, and one that takes StructType and varargs. In cases where there isn't a struct type convenient, we now add a ConstantStruct::getAnon method (whose name will make more sense after a few more patches land). It would be "really really nice" if the ConstantStruct::get and ConstantVector::get methods didn't make temporary std::vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133412 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | optimizations when emitting calls to the function; instead those calls may use faster relocations which require the function to be immediately resolved upon loading the dynamic object featuring the call. This is useful when it is known that the function will be called frequently and pervasively and therefore there is no merit in delaying binding of the function. Currently only implemented for x86-64, where it turns into a call through the global offset table.
