https://gcc.gnu.org/pipermail/gcc-patches/2022-August/599276.html gives a good

The ideal PRU code sequence for the snippet would be:
char test(uint64_t a, uint64_t b)
{
return a && b;

or r16, r16, r17
uminr14, r14, 1

With cbranchdi4 defined, the generated code is now 10 instructions:
test:
qbne.L5, r15, 0
qbeq.L4, r14, 0
.L5:
rsb r0, r16, 0
rsc r1, r17, 0

in many places in middle end to use REGMODE_NATURAL_SIZE instead of word_mode.
That however proved too intrusive. And I don't
