Struct melior::dialect::ods::memref::ExtractAlignedPointerAsIndexOperation

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

An extract_aligned_pointer_as_index operation. Extracts a memref’s underlying aligned pointer as an index.

Extracts the underlying aligned pointer as an index.

This operation is useful for lowering to lower-level dialects while still avoiding the need to define a pointer type in higher-level dialects such as the memref dialect.

This operation is intended solely as step during lowering, it has no side effects. A reverse operation that creates a memref from an index interpreted as a pointer is explicitly discouraged.

Example:

  %0 = memref.extract_aligned_pointer_as_index %arg : memref<4x4xf32> -> index
  %1 = arith.index_cast %0 : index to i64
  %2 = llvm.inttoptr %1 : i64 to !llvm.ptr<f32>
  call @foo(%2) : (!llvm.ptr<f32>) ->()
