Hi. After requesting to install julia it requires libunwind, but I want to use llvm-libunwind if possible. Is this a posible option? Thank you for your time. -------------------------------------------------------------------------------- These are the packages that would be merged, in order: Calculating dependencies... done!

I was trying that just now just to be lazy in switching, and just to say that it doesn't work. debuginfo.cpp:772:13: error: 'unw_get_proc_info_by_ip' was not declared in this scope; did you mean 'unw_get_proc_info'? https://discourse.julialang.org/t/porting-julia-to-other-platforms-llvm-libunwind/575
The only workaround that I can offer is to use dev-lang/julia-bin, which does not depend on sys-libs/libunwind. I am not sure there is anything we can do downstream. Porting julia to be compatible with llvm-libunwind would be something that upstream has to support and maintain.
