| 2011-04-09 | Precompute interference for neighbor blocks as long as there is no interference. | Jakob Stoklund Olesen | |
| This doesn't require seeking in the live interval union, so it is very cheap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129187 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
| 2011-04-02 | Add an InterferenceCache class for caching per-block interference ranges. | Jakob Stoklund Olesen | |
| When the greedy register allocator is splitting multiple global live ranges, it tends to look at the same interference data many times. The InterferenceCache class caches queries for unaltered LiveIntervalUnions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128764 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
