Subject: CellSPU doesn't appear to support fully the "ISD::ROTR" operation. The DAG
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=70fcb6bf58268798b9b3ee7983eb9c9e1aed4811;p=oota-llvm.git

CellSPU doesn't appear to support fully the "ISD::ROTR" operation. The DAG
combiner can now generate ROTR if the backend says that it can handle it. Cell
SPU says this, but gets an error from code gen saying that it can't select
ROTR. I'm xfailing this test until this can be fixed.
