2006-08-03Changes:Chris Lattner
1. Update an obsolete comment. 2. Make the sorting by base an explicit (though still N^2) step, so that the code is more clear on what it is doing. 3. Partition uses so that uses inside the loop are handled before uses outside the loop. Note that none of these changes currently changes the code inserted by LSR, but they are a stepping stone to getting there. This code is the result of some crazy pair programming with Nate. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29493 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-02- Change AssignTopologicalOrder to return vector of SDNode* by reference.Evan Cheng
- Tweak implementation to avoid using std::map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29479 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-02AssignTopologicalOrder now returns the vector of SDNode* by reference toEvan Cheng
avoid the expensive operation of copying a vector. It also returns a maximum id by value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29478 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-02Use of vector<bool> causes some horrendous compile time regression (2x)!Evan Cheng
Looks like libstdc++ implementation does not scale very well. Switch back to using directly managed arrays. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29469 91177308-0d34-0410-b5e6-96231b3b80d8

problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29468 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-02Add special check to avoid isLoop call. Simple, but doesn't seem to speedChris Lattner
up lcssa much in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29465 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-02Speed up Loop::isLCSSAForm by using a binary search and single-entry cache.Chris Lattner
This reduces LCSSA pass time from 1.5s to 0.96s when run on eon in release+asserts mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29464 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-02Replace the SSA update code in LCSSA with a bottom-up approach instead of a topChris Lattner
down approach, inspired by discussions with Tanya. This approach is significantly faster, because it does not need dominator frontiers and it does not insert extraneous unused PHI nodes. For example, on 252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest pass in gccas) from 9.14s to 0.74s on my G5. This code is also slightly smaller and significantly simpler than the old code. Amusingly, in a normal Release build (which includes the "assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA is in LCSSA form is actually slower than the LCSSA transformation pass itself on 252.eon. I will see if Loop::isLCSSAForm can be sped up next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29463 91177308-0d34-0410-b5e6-96231b3b80d8
