Struct melior::dialect::ods::arith::NegFOperation

pub struct NegFOperation<'c> { /* private fields */ }

A negf operation. Floating point negation.

The negf operation computes the negation of a given value. It takes one operand and returns one result of the same type. This type may be a float scalar type, a vector whose element type is float, or a tensor of floats. It has no standard attributes.

Example:

// Scalar negation value.
%a = arith.negf %b : f64

// SIMD vector element-wise negation value.
%f = arith.negf %g : vector<4xf32>

// Tensor element-wise negation value.
%x = arith.negf %y : tensor<4x?xf8>
