I fixed several issues in mold related to POWER10 compatibility, and all its
unit tests pass on gcc120! I also confirmed that mold can now bootstrap itself
with `-mcpu=power10`. So I believe it's now usable

Last time I tried, mold-produced binaries crash on a real POWER10 machine, but
I couldn't debug it due to some issue (gdb's issue or something but I don't
remember exactly what that was.) Let me try again

I noticed some Power10 mold code was committed in March. Does that mean this
is "fixed" in mold now? If

It seems you are saying that as long as GCC emits code according to the Holy
Scripture that is the ABI spec, everything is fine. I imagine on other
architectures maintainers are able to consider how

What makes you think we need to tell the user to do something? There is
nothing that needs to be done as far as I can see? /confused

Are you guys really sure you want to blame the user here, considering that all
linkers, including the BFD linker, initially misinterpreted the ABI the same
way?

We're working to add a Power10 system to the Compile Farm. The systems are at
OSUOSL, but Power10 doesn't have official KVM support so the interface to the
OpenStack management system is complicated.

I'm the maintainer of the mold linker. I didn't implement that POWER10 ABI
because I didn't have an access to a POWER10 machine and therefore couldn't
verify the correctness of my implementation.

To expand a bit: st_other with value 1 was reserved before, and now it
isn't anymore. Any tool that silently ignores the "special case" of
reserved values will not work correctly (it might sometimes

Alan implemented the special case of .localentry 1 in this patch for the BFD
linker (that appeared in binutils 2.32 if my calculations are correct):
