--- Comment #5 from Andreas Schwab <sch...@linux-m68k.org> ---
With that patch, *lea is used in more places and LRA fails to remove the inner
SUBREG.

../../../gcc/libgcc/libgcov-profiler.c: In function ‘__gcov_interval_profiler’:
../../../gcc/libgcc/libgcov-profiler.c:46:1: error: insn does not satisfy its
