What did you expect to see?

Build successfully.
A successor of #62465 , but no the same issue.

[mauri870]

We are facing the same issue in rqlite/rqlite#1682.

[mauri870]

cc @golang/riscv64 @golang/compiler

[mauri870]

As an update, this failure seems to go away if I revert CL 520095.

[cherrymui]

That CL addresses #62465, so we probably could not simply revert.

[gopherbot]

Change https://go.dev/cl/567375 mentions this issue: cmd/link/internal/riscv64: generate local text symbols for R_RISCV_CALL

[4a6f656c]

@cherrymui seems like something we could/should backport?

It can be avoided/worked around by using internal linking, rather than forcing external linking.

[cherrymui]

I think it is reasonable to backport. Internal linking is not the default mode, and has limitations.

@gopherbot please backport this to Go 1.22. Thanks.

[gopherbot]

Backport issue(s) opened: #66060 (for 1.22).

Remember to create the cherry-pick CL(s) as soon as the patch is submitted to master, according to https://go.dev/wiki/MinorReleases.
