变更摘要
此 PR 修复了 aclnnPow 算子在 exp=1 时的处理策略:当指数为 1.0 时,幂运算结果恒等于输入本身(x¹ = x),因此无需执行实际的幂运算,直接返回输入张量即可。该改动在 aclnnPowTensorScalarGetWorkspaceSize 函数中新增了 canNoUseOp 标志及对应的短路分支,使得张量^标量(TensorScalar)路径在 exponent=1 时跳过 Pow 计算,避免不必要的算子调用。
主要改动
- 新增
canNoUseOp标志判断:在aclnnPowTensorScalarGetWorkspaceSize函数中新增bool canNoUseOp = static_cast<float>(exponent->ToFloat()) == NOOP_EXP && !IsRegBase();,用于判定指数是否为1.0(即常量NOOP_EXP)。 - 新增 exp=1 短路分支:在
CheckSupportPows和canUseSquare分支之后,新增else if (canNoUseOp)分支,直接将selfCast作为计算结果返回,跳过后续Pow算子调用。 - 适用范围:该优化仅在非
IsRegBase()平台生效,与已有的canUseSquare(exp=2)优化策略保持一致。
