The ISel lowering for global TLS access in PIC mode was creating a pseudo instruction that is later expanded to a call, but the code was not setting the hasCalls flag in the MachineFrameInfo alongside the adjustsStack flag. This caused some functions to be mistakenly recognized as leaf functions, and this in turn affected the decision to eliminate the frame pointer. With the fix, hasCalls is properly set and the leaf frame pointer is correctly preserved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221695 91177308-0d34-0410-b5e6-96231b3b80d8
