Changes in directory llvm/utils/TableGen:
DAGISelEmitter.cpp updated: 1.206 -> 1.207
---
Log message:
Can't trust NodeDepth when checking for possibility of load folding creating
a cycle. This increase the search space and will increase compile time (in
practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec)
that will be addressed later.
