--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
It is the same issue from BZ#31244, where the rewrite done by
b33e946fbb1659d2c5937c4dd756a7c49a132dff was not fully correct regarding CFI
annotation. I will send a similar fix as proposed to fix the sparc32 issue:

It fixes the regression I saw on sparc64:
