Andrew Trick 7f72633547 Put a limit on ScheduleDAGSDNodes::ClusterNeighboringLoads to avoid blowing up compile time. ... Fixes PR16365 - Extremely slow compilation in -O1 and -O2. The SD scheduler has a quadratic implementation of load clustering which absolutely blows up compile time for large blocks with constant pool loads. The MI scheduler has a better implementation of load clustering. However, we have not done the work yet to completely eliminate the SD scheduler. Some benchmarks still seem to benefit from early load clustering, although maybe by chance. As an intermediate term fix, I just put a nice limit on the number of DAG users to search before finding a match. With this limit there are no binary differences in the LLVM test suite, and the PR16365 test case does not suffer any compile time impact from this routine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205738 91177308-0d34-0410-b5e6-96231b3b80d8		2014-04-07 21:29:22 +00:00
