* | Don't pull a load through a callseq_start if the load's chain | Dan Gohman | 2009-09-15 | 1 | -0/+23 |
has multiple uses, as one of the other uses may be on a path to a different node above the callseq_start, because that leads to a cyclic graph. This problem is exposed when -combiner-global-alias-analysis is used. This fixes PR4880. llvm-svn: 81821 |
