--- Comment #6 from Stephen Warren <swarren at nvidia dot com> --- > Note that library code also assumes that misaligned accesses are safe: > that is the default for AArch64. I assume you're talking about gcc's default, not any architectural default? The ARMv8 ARM states that SCTLR_ELx.A doesn't have an architecturally defined reset value (i.e. default). (Sorry if this shows up twice; I typed it this morning and thought I submitted it, but it hasn't shown up). Thanks.
