You can just use hook_bool_void_false for this (and hook_bool_void_true
for e.g. the rs6000 implementation).
Yes, much nicer and smaller patch using those functions! So here's version 3,
which is the same as version 2 but using above mentioned hook functions.
This is currently bootstrapping right now, ok now assuming no regressions?
Ok for me. Thank you for working on this issue, Peter.
