But I cross build for TARGET_ARCH=3Darmv6 with: > XCFLAGS+=3D -march=3Darmv7-a -mcpu=3Dcortex-a7 > XCXXFLAGS+=3D -march=3Darmv7-a -mcpu=3Dcortex-a7 (And similarly for self-hosted.) It may be that the -march and/or -mcpu = matter to the code generation and explain my lack of problems. The builds also have INVARIANTS and WITNESS off. =3D=3D=3D Mark Millard markmi at dsl-only.net
