Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed| |2020-11-17 Ever confirmed|0 |1 Status|UNCONFIRMED |WAITING --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- restrict is necessary because of possible aliasing (you see the runtime alias test). For orr r3, r2, r0 orrs r3, r3, r1 lsls r3, r3, #28 bne .L2 it looks like this is a runtime alignment test - does the specified arch support unaligned vector loads/stores?
