--- Comment #2 from Uroš Bizjak <ubizjak at gmail dot com> ---
The compile failure with the testcase from Comment #0 has gone latent, but the
problem looks similar to PR 58792 [1].
On a related note, the allocator introduces extra move for pr30185.c testcase
that results in:
foo:
movq %rsi, %rax
cqto
idivq %rcx
movq %rax, %rsi <---- here (*)
xorl %eax, %eax
movq %rsi, %rdx
ret
"movq %rax, %rdx" should be emitted at (*).
