Seems like setcontext is being deprecated everywhere, Mac, BSDs, Alpine etc. Post about its replacement https://stackoverflow.com/questions/4298986/is-there-something-to-replace-the-ucontext-h-functions |
|
@djwatson, can libunwind switch to the alternative and stop using the obsolete ucontext? |
|
Yes, definitely. I haven't had time to do this yet, if you have a patch I will happily merge it. |

Libunwind provides a sigreturn stub for x86 in version 1.2 [1]. However
the arch still depends on setcontext() which is unavailable in musl-libc
and which is supposed to be "deprecated everywhere" [2]

setcontext is also deprecated and not present on x86 android. It would be nice if x86 would provide its own setcontext.S, similar to x86_64
