There is a reasonable chance that this patch broke mips64 n64 but I do not have
confirmation yet. See PR target/78660.
I can vaguely see how this patch may affect MIPS64 in terms of how 32-bit
values are handled on a MIPS64 architecture with the sign bit replicated to the
upper-32 bits. This presumably is somehow not accounted for in the nonzero_bits
logic.
I'm yet to get my head around what the issue is but if anyone has a pointer
based on the potential impact on MIPS64 as described above then I'd be
grateful.
