2008-11-05Eliminate the ISel priority queue, which used the topological order for aDan Gohman
priority function. Instead, just iterate over the AllNodes list, which is already in topological order. This eliminates a fair amount of bookkeeping, and speeds up the isel phase by about 15% on many testcases. The impact on most targets is that AddToISelQueue calls can be simply removed. In the x86 target, there are two additional notable changes. The rule-bending AND+SHIFT optimization in MatchAddress that creates new pre-isel nodes during isel is now a little more verbose, but more robust. Instead of either creating an invalid DAG or creating an invalid topological sort, as it has historically done, it can now just insert the new nodes into the node list at a position where they will be consistent with the topological ordering. Also, the address-matching code has logic that checked to see if a node was "already selected". However, when a node is selected, it has all its uses taken away via ReplaceAllUsesWith or equivalent, so it won't recieve any further visits from MatchAddress. This code is now removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58748 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04- Add a "getOrInsertGlobal" method to the Module class. This acts similarly toBill Wendling
"getOrInsertFunction" in that it either adds a new declaration of the global and returns it, or returns the current one -- optionally casting it to the correct type. - Use the new getOrInsertGlobal in the stack protector code. - Use "splitBasicBlock" in the stack protector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58727 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-04Update in response to feedback from Chris:Bill Wendling
- Use enums instead of magic numbers. - Rework algorithm to use the bytes size from the target to determine when to emit stack protectors. - Get rid of "propolice" in any comments. - Renamed an option to its expanded form. - Other miscellanenous changes.
