[LLVMdev] Instruction Scheduling - migration from v3.1 to v3.2
...he llvm/clang derived compiler for our processor from the
v3.1 to v3.2 codebase. This has mostly gone well except that instruction
latency scheduling is no longer happening.
The people who implemented this previously sub-classed 'ScheduleDAGInstrs'
and implemented the virtual methods 'computeLatency' and
'computeOperandLatency'. However, these methods have been removed from
'ScheduleDAG' and 'ScheduleDAGInstrs' so are no longer invoked on our
implementation. Instead, the correct approach seems to implement a
sub-class of 'TargetSchedModel'.
