--- Comment #9 from Thomas Preud'homme <thopre01 at gcc dot gnu.org> --- Managed to reach a state where nothing is spilled on the stack for Thumb-1 either. I want to do 3 more changes before I start full testing: - put some compiler barrier between address computation and canari setting / canari check to ensure no instruction is scheduled between the two - clarify in documentation that it's the target's responsability to ensure guard's address computation is not CSE (in particular for PIC access) - tighten scan pattern for testcase a bit more
