--- Comment #2 from Hao Liu <hliu at amperecomputing dot com> --- > Is the warning from some static analyzer? No. I just find it maybe a bug while looking at the code. > slp should be true always (always do analyze slp), it doesn't care what's in > slp_done_for_suggested_uf. Oh, I see. This is not a real bug. IMHO, it would be better to initialize it as "false", which should be much easier for someone to understand the code.
