It seems to me, that if vg were present in the xml, and honored by gdb, that the xml for the rest of the registers *could* describe the maximum register width as opposed to the current register width. At which point this wouldn't need to be dynamic at all -- merely have a comment next to ARM_MAX_VQ that changes must be reflected in the gdb xml file too. Which I expect to never happen. But again, this is how gdb works today, so Acked-by: Richard Henderson <richard.hender...@linaro.org> r~
