--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> --- I think there is another very similar bug report. # buf_1 = PHI <&stack_buf(2), buf_15(6)> [...] if (&stack_buf != buf_1) in each branch, we thus know what buf_1 is, so we could replace it with buf_15 in # _3 = PHI <_17(5), buf_1(4)> return _3; (or is that bad for register pressure?) Or use it as a hint to thread that path, or add some logic to Wreturn_local_addr, but that's getting more complicated.
