Jakob Stoklund Olesen 2cd2111959 Defer SplitKit value mapping until all defs are available. ... The greedy register allocator revealed some problems with the value mapping in SplitKit. We would sometimes start mapping values before all defs were known, and that could change a value from a simple 1-1 mapping to a multi-def mapping that requires ssa update. The new approach collects all defs and register assignments first without filling in any live intervals. Only when finish() is called, do we compute liveness and mapped values. At this time we know with certainty which values map to multiple values in a split range. This also has the advantage that we can compute live ranges based on the remaining uses after rematerializing at split points. The current implementation has many opportunities for compile time optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124765 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-03 00:54:23 +00:00
