I'm applying this patch again now, this time with a tweak to expmed.c
to prevent the false positive warning from breaking bootstrap. I
don't see any problem in the gimple output, so the bug must be in the
middle-end somewhere.

Hi Jason,
This commit caused boot-strap failure on aarch64. Is it a bug? Can this be
fixed ASAP?
../../gcc/gcc/expmed.c:5602:19: error: ���int_mode��� may be used uninitialized
in this function [-Werror=maybe-uninitialized]
5602 | scalar_int_mode int_mode;

This breaks bootstrap on aarch64 (during stage2 build):

rtx, machine_mode, int, int, machine_mode)':
