The reference to qemu-user-static was meant to be for with /nxb-bin/. . . (or some form of native tools). It is the native tools that initially have MACHINE_ARCH being amd64 by default for the example contexts. Absent that, qemu-arm-static would likely report armv6 for all arm's until the explicit assignment. (The "armv6" is a single compile-time constant in the qemu-arm-static source at this time.) So this likely would behave as on a native build: -O . > And that leads to questioning the need for -O instead of -O2 > for armv[67] and possibly some mips contexts. > > Or, going the other way: Should -O be forced and have an > exp run for, say armv7 ?
