08:30 <re_irc> <@diondokter:matrix.org> Is there a way in Rust to do weak linkage in Rust?

08:30 <re_irc> In "cortex-m-rt" they kind of do it with the Hardfault, but the 'weak' function still remains in the binary and takes up 2 bytes.

08:33 <re_irc> <@diondokter:matrix.org> From the looks of it no...

08:53 <re_irc> <@9names:matrix.org> compiler_builtins uses "#[linkage = "weak"]", but it looks like it's unstable.

08:53 <re_irc> https://github.com/rust-lang/rust/issues/29603

08:53 <re_irc> <@diondokter:matrix.org> Yeah, I need it stable. And the linkage feature has been unstable since 2015 :P

10:46 <re_irc> <@jamesmunns:beeper.com> : You uh, could use binutils to manually weaken symbols after creating an object like a staticlib

10:47 <re_irc> <@jamesmunns:beeper.com> I've used this in anger before: https://github.com/rust-lang/compiler-builtins/issues/345#issuecomment-975866310

10:48 <re_irc> <@diondokter:matrix.org> Haha, I asked this because I discovered the hard fault symbol being left in for cortex-m-rt

10:48 <re_irc> <@jamesmunns:beeper.com> But yeah, still no native weak linkage.

10:49 <re_irc> <@jamesmunns:beeper.com> Weak functions will still always make it to the final binary, unless you "override" them with something else

10:49 <re_irc> <@jamesmunns:beeper.com> Are you saying you override it but the weak one ALSO still exists?

10:50 <re_irc> <@diondokter:matrix.org> Anyways, made a PR https://github.com/rust-embedded/cortex-m/pull/476

10:50 <re_irc> <@diondokter:matrix.org> Check out what it does with the `HardFault_` function

10:51 <re_irc> <@diondokter:matrix.org> That supposedly weak function still remains in the final binary when it is overridden

18:05 <re_irc> <@shakencodes:matrix.org> : Alex, I am working with the stm32wlxx-hal building up infrastructure for a production development. I would like to understand your impression of the crate's maturity and where it needs improvement. (If we go forward on this platform, we will be happy to reflect PRs back with any improvements made.)

18:06 <re_irc> I am happy to have this chat in an open forum, but wanted to give you the opportunity to chat privately first.
