Summary: Tablegen tries to infer this from the selection DAG patterns defined for the instructions, but it can't always. An instructive example is CLZr64. CLZr32 is correctly inferred to have no side-effects, but the selection DAG pattern for CLZr64 is slightly more complicated, and in particular the ctlz DAG node is not at the root of the pattern. Thus tablegen can't infer that CLZr64 has no side-effects. Reviewers: jholewinski Subscribers: jholewinski, tra, llvm-commits Differential Revision: http://reviews.llvm.org/D17472 llvm-svn: 265089 |
