[LLVMdev] Complex load patterns and token factors
Working on a target I added this pattern:
def : Pat<(v4i64 (load xoaddr:$src)),
(QVFCTIDb (QVLFDXb xoaddr:$src))>;
which represents an actual load followed by a necessary conversion
operation. The problem is that when this matches any TokenFactor that
was attached to the load node gets attached, not to the inner load
instruction, but the outer conversion operation. This is
