07:05 <re_irc> <ub|k> has anyone managed to use "once_cell" on embedded?

08:04 <re_irc> <ub|k> hm... i'm currently not able to compile lazy_static on embedded... is it due to this regression in atomics for embedded devices in rustc someone mentioned some time ago?

08:06 <re_irc> <ub|k> "error[E0599]: no method named "compare_and_swap"found for struct"AtomicBool" in the current scope"

08:14 <re_irc> <dirbaio> is it rp2040? that's thumbv6m, CAS has never been available there

08:18 <re_irc> <dirbaio> (the regression was something else, it was removing "load"/"store", and it's been reverted)

08:20 <re_irc> <ub|k> dirbaio: indeed. ok, thanks. what do people use on that target then?

08:21 <re_irc> <ub|k> i was convinced I had used lazy_static on the rp2040 before, but I probably mixed up with stm32

08:22 <re_irc> <dirbaio> for atomic CAS you can use "atomic-polyfill"

08:22 <re_irc> <ub|k> ah cool

08:22 <re_irc> <ub|k> or maybe I'll just keep it simple and use an "Option<_>"

08:23 <re_irc> <dirbaio> for LazyCell/OnceCell you'll have to patch, or copypaste them into your crate, to make them use "atomic-polyfill"... :(

08:24 <re_irc> <ub|k> yeah, "Option" it is
