Jakob Stoklund Olesen 35071a0847 Disable physical register coalescing when the number of live ranges for the ... physreg becomes ridiculously high. std::upper_bound may be log(N), but for sufficiently large live intervals, it becomes log(N)*cachemiss = a long long time. This patch improves coalescer time by 4500x for a function with 20000 function calls. The generated code is different, but not significantly worse - the allocator hints are almost as good as physreg coalescing anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98023 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-09 00:59:48 +00:00
