Struct melior::dialect::ods::math::FmaOperation

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

A fma operation. Floating point fused multipy-add operation.

Syntax:

operation ::= ssa-id `=` `math.fma` ssa-use `,` ssa-use `,` ssa-use `:` type

The fma operation takes three operands and returns one result, each of these is required to be the same type. Operands must be of floating point type (i.e., scalar, tensor or vector).

Example:

// Scalar fused multiply-add: d = a*b + c
%d = math.fma %a, %b, %c : f64

The semantics of the operation correspond to those of the llvm.fma intrinsic. In the particular case of lowering to LLVM, this is guaranteed to lower to the llvm.fma.* intrinsic.
