Subject: [Bug rtl-optimization/108273] Inconsistent dfa state between debug and non-debug
Date: Thu, 23 Feb 2023 09:08:51 +0000	[thread overview]
Message-ID: <bug-108273-4-FVgMVobxJf@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #4 from Kewen Lin <linkw at gcc dot gnu.org> ---
Starting from r13-5154-g733a1b777f16cd, this failure is gone on Power10 LE (or
with explicit -mcpu=power10), but it shows up on Power8 LE. By checking
r13-5154, this behavior change is expected, the priorities of some insns change
due to that commit, it further affects the scheduling decision on which insn is
scheduled ahead.
