Struct melior::dialect::ods::llvm::UndefOperation

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

A mlir.undef operation. Creates an undefined value of LLVM dialect type..

Unlike LLVM IR, MLIR does not have first-class undefined values. Such values must be created as SSA values using llvm.mlir.undef. This operation has no operands or attributes. It creates an undefined value of the specified LLVM IR dialect type.

Example:

// Create a structure with a 32-bit integer followed by a float.
%0 = llvm.mlir.undef : !llvm.struct<(i32, f32)>
