2004-02-08Switch the Nodes list from being an std::vector<DSNode*> to an ilist<DSNode>Chris Lattner

2004-02-08One of the 'annoying' things about ilists is that the iterators don't behaveChris Lattner
quite the same as for non-intrusive lists of pointers to nodes. To support transitioning code bases, add a new 'compatibility' iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11172 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-07Abstract out the Nodes collection. Instead of providing a getNodes() method,Chris Lattner
provide node_begin/end iterators, which are only guaranteed to be bidirectional, not random access. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11165 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-05Fix another dominator update bug. These bugs keep getting exposed because GCSEChris Lattner
keeps finding more code motion opportunities now that the dominators are correct! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11142 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-05Change live interval representation. Machine instructions now have twoAlkis Evlogimenos
slots each. As a concequence they get numbered as 0, 2, 4 and so on. The first slot is used for operand uses and the second for defs. Here's an example: 0: A = ... 2: B = ... 4: C = A + B ;; last use of A The live intervals should look like: A = [1, 5) B = [3, x) C = [5, y) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11141 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-05Fix PR223: Loopsimplify incorrectly updates dominator informationChris Lattner
The problem is that the dominator update code didn't "realize" that it's possible for the newly inserted basic block to dominate anything. Because it IS possible, stuff was getting updated wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11137 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-05In a "seeing the forest through the trees" kinda situation, I realized that aChris Lattner
complete rewrite of load-vn will make it a bit faster. This changes speeds up the gcse pass (which uses load-vn) from 25.45s to 0.42s on the testcase in PR209. I've also verified that this gives the exact same results as the old one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11132 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-05This is a big diff with no functionality change. We just reorder some code,Chris Lattner

2004-02-04Two changes:Chris Lattner
1. Don't scan to the end of alloca instructions in the caller function to insert inlined allocas, just insert at the top. This saves a lot of time inlining into functions with a lot of allocas. 2. Use splice to move the alloca instructions over, instead of remove/insert. This allows us to transfer a block at a time, and eliminates a bunch of silly symbol table manipulations. This speeds up the inliner on the testcase in PR209 from 1.73s -> 1.04s (67%) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11118 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04IMULri* instructions do not require their first two registers operandsAlkis Evlogimenos
to be the same (IOW they are not two address instructions). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11117 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-04Optimize the case where we are inlining a function that contains only one ↵Chris Lattner
basic block, and that basic block ends with a return instruction. In this case, we can just splice the cloned "body" of the function directly into the source basic block, avoiding a lot of rearrangement and splitBasicBlock's linear scan over the split block. This speeds up the inliner on the testcase in PR209 from 2.3s to 1.7s, a 35% reduction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11116 91177308-0d34-0410-b5e6-96231b3b80d8
