--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
I'll try to bisect that, on aarch64 machine I see:
../../gcc/config/aarch64/cortex-a57-fma-steering.c: In member function ‘void
func_fma_steering::analyze()’:
../../gcc/config/aarch64/cortex-a57-fma-steering.c:979:53: error: ‘head’ may be
used uninitialized in this function [-Werror=maybe-uninitialized]
this->analyze_fma_fmul_insn (forest, chain, head);
^
../../gcc/config/aarch64/cortex-a57-fma-steering.c:979:53: error: ‘forest’ may
be used uninitialized in this function [-Werror=maybe-uninitialized]
../../gcc/config/aarch64/cortex-a57-fma-steering.c:979:53: error: ‘chain’ may
be used uninitialized in this function [-Werror=maybe-uninitialized]
I'll try to bisect..
