-Subject: [PATCH] xtensa: fix PR target/91880
-
-Xtensa hwloop_optimize segfaults when zero overhead loop is about to be
-inserted as the first instruction of the function.
-Insert zero overhead loop instruction into new basic block before the
-loop when basic block that precedes the loop is empty.
