hlfir.copy_in implements copying non-contiguous array slices for functions that take in arrays required to be contiguous through flang-rt. For large arrays of trivial types, this can incur overhead compared to a plain, inlined copy loop. To address that, add a new InlineHLFIRCopyIn optimisation pass to inline hlfir.copy_in operations for trivial types. For the time being, the pattern is only applied in cases where the copy-in does not require a corresponding copy-out, such as when the function being called declares the array parameter as intent(in). Applying this optimisation reduces the runtime of thornado-mini's DeleptonizationProblem by about 10%. --------- Signed-off-by: Kajetan Puchalski <kajetan.puchalski@arm.com>
