man gcc:
Warn if in a loop with constant number of iterations the compiler
detects undefined behavior in some statement during one or more of
the iterations.
Milkymist pfpu has no jump instructions, so checking for MICROCODE_WORDS
instructions should have kept us in bounds of s->microcode, but i++
allowed one loop too many,
hw/misc/milkymist-pfpu.c: In function ‘pfpu_write’:

hw/misc/milkymist-pfpu.c:167:14: note: possible undefined statement is here

The code can still access out of bounds, because it presumes that PC register
always begins at 0, and we allow writing to it.

By preferring bool over int where sensible, but without modifying any
