Surya's recent patch to IRA improves the code for sh/pr54602-1.c

As a result there literally aren't any insns that can be used to fill
the delay slot of the return, so a nop gets emitted and the test fails.
Given there literally aren't any insns to move into the delay slot, the
best course of action is to just drop the test.
Pushed to the trunk.

I can't reproduce what you are saying.
Which triplet and flags is your test setup using?
For this test case, GCC 13 with -m4 -ml -O1 -fno-pic:
No -m flags at all. As plain of a testrun as you can do.
