Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |critical Last reconfirmed| |2024-01-18 Ever confirmed|0 |1 Status|UNCONFIRMED |NEW --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- cfun->machine->advsimd_zero_insn use is plain wrong. As the RTL could be removed fully from the RTL stream and then it will be GC'ed. Plus I really doubt using emit_insn_before with function_beg_insn during split is going to work correctly.
