* Remove trailing whitespaceMisha Brukman2005-04-211-6/+6

* Switch from using an ilist for uses to using a custom doubly linked list.Chris Lattner2005-02-011-80/+50
| | | | | | | | | | | | | | | | | | | | | This list does not provide the ability to go backwards in the list (its more of an unordered collection, stored in the shape of a list). This change means that use iterators are now only forward iterators, not bidirectional. This improves the memory usage of use lists from '5 + 4*#use' per value to '1 + 4*#use'. While it would be better to reduce the multiplied factor, I'm not smart enough to do so. This list also has slightly more efficient operators for manipulating list nodes (a few less loads/stores), due to not needing to be able to iterate backwards through the list. This change reduces the memory footprint required to hold 176.gcc from 66.025M -> 57.687M, a 14% reduction. It also speeds up the compiler, 7.73% in the case of bytecode loading alone (release build loading 176.gcc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19956 91177308-0d34-0410-b5e6-96231b3b80d8

* Adjust to ilist changes.Chris Lattner2005-01-291-13/+25
| | | | | | | | | | Based on the ilist changes avoid allocating an entire Use object for the end of the Use chain. This saves 8 bytes of memory for each Value allocated in the program. For 176.gcc, this reduces us from 69.5M -> 66.0M, a 5.3% memory savings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19925 91177308-0d34-0410-b5e6-96231b3b80d8

this list (except use_size()) are constant time. Before the killUse method (used whenever something stopped using a value) was linear time, and thus very very slow for large programs. This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc: 176.gcc: 77.07s -> 37.38s 177.mesa: 7.59s -> 5.57s 252.eon: 21.02s -> 19.52s (*) 253.perlbmk: 11.40s -> 13.05s 254.gap: 7.25s -> 7.42s 252.eon would speed up a whole lot more, but optimization time is being dominated by the inlining pass, which needs to be fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9159 91177308-0d34-0410-b5e6-96231b3b80d8
