 rename meta/recipes-support/libunwind/{libunwind_1.6.2.bb => libunwind_1.8.1.bb} (92%)

I started doing this upgrade some time ago and it’s non-trivial…

Did you verify that ppc/mips/arm all build with both gcc and clang?

You are right. I somehow had something working on arm64, and was surprised that the patches didn't seem to need refreshing.
Of course they need refreshing, and I really don't know what I built there...

My apologies. I will be back.

https://git.yoctoproject.org/poky-contrib/log/?h=ross/libunwind is as far as I got. Maybe some more fixes have landed upstream since then.

This looks pretty up-to-date.
The mips-byte-order.patch (set to apply=0 in your branch) is still needed, and has not yet been merged upstream.
With that I was able to successfully "bitbake libunwind" for the x86, arm, mips, and ppc qemu machines, both 32 and 64bit, with and without TOOLCHAIN=clang, and with and without TCLIBC=musl.

Do you remember if you had any specific issues when you worked on this last year?

I guess we should put this on the autobuilder and see what comes up?
