These intrinsics are legalized to V(ALL|ANY)_(NON)?ZERO nodes, are matched as SN?Z_[BHWDV]_PSEUDO pseudo's, and emitted as a branch/mov sequence to evaluate to 0 or 1. Note: The resulting code is sub-optimal since it doesnt seem to be possible to feed the result of an intrinsic directly into a brcond. At the moment it uses (SETCC (VALL_ZERO $ws), 0, SETEQ) and similar which unnecessarily evaluates the boolean twice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189478 91177308-0d34-0410-b5e6-96231b3b80d8
