--- Comment #3 from Keno Fischer <keno at juliacomputing dot com> --- > I am going to close it as won't fix as the problem is with the rr emulator > which needs to emulate ll/sc for correctness. No currently shipping aarch64 chip provides hardware support that would allow such a capability (believe me, we've tried and have and many conversations with the hardware vendors about it). I would like to strongly request that the WONTFIX be reconsidered here. It's a relatively simple fix, that should not have any downsides. If this is not fixed upstream in libgcc then distributions that want to provide rr will need to start patching libgcc downstream or find another solution, which will just be a huge mess.
