It corrects the shift type of interleaved stepped patterns for const vector
expanding in LRA. The shift instruction was initially LSHIFTRT, and it seems
still should be the same type for both LRA and other cases.
This is OK, thanks.

This patch adds the ability to fold the address computation into the addressing
mode for LDAPR instructions using LDAPUR when RCPC2 is available.
LDAPUR emission is controlled by the tune flag enable_ldapur, to enable it on a
per-core basis. Earlier, the following code:

Hi,
More of the review will be later, but I have noticed that you have added
preconditions checks
to the layouts, and then avoid checking them inside the operator[] of the
mdspan. This is general
sounds good.
However, the precondition on mdspan::operator[] is now hardened:
