* Too many changes in one commit:Alkis Evlogimenos2004-02-205-170/+324
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. LiveIntervals now implement a 4 slot per instruction model. Load, Use, Def and a Store slot. This is required in order to correctly represent caller saved register clobbering on function calls, register reuse in the same instruction (def resues last use) and also spill code added later by the allocator. The previous representation (2 slots per instruction) was insufficient and as a result was causing subtle bugs. 2. Fixes in spill code generation. This was the major cause of failures in the test suite. 3. Linear scan now has core support for folding memory operands. This is untested and not enabled (the live interval update function does not attempt to fold loads/stores in instructions). 4. Lots of improvements in the debugging output of both live intervals and linear scan. Give it a try... it is beautiful :-) In summary the above fixes all the issues with the recent reserved register elimination changes and get the allocator very close to the next big step: folding memory operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11654 91177308-0d34-0410-b5e6-96231b3b80d8
