Jakob Stoklund Olesen c7f44b8b8f Compute instruction heights through a trace. ... The height on an instruction is the minimum number of cycles from the instruction is issued to the end of the trace. Heights are computed for all instructions in and below the trace center block. The method for computing heights is different from the depth computation. As we visit instructions in the trace bottom-up, heights of used instructions are pushed upwards. This way, we avoid scanning long use lists, looking for uses in the current trace. At each basic block boundary, a list of live-in registers and their minimum heights is saved in the trace block info. These live-in lists are used when restarting depth computations on a trace that converges with an already computed trace. They will also be used to accurately compute the critical path length. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161138 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-01 22:36:00 +00:00
