4. It seems the __ARM_ARCH==7 test is not quite good enough, I get:

Just guessing, but something along the lines of this might do for
coro_transfer? (I haven't been able to test it):

         #if __VFP_FP__
           "\tvpush {d8-d15}\n"
           #define NUM_SAVED (9 + 8 * 2)
         #else
           #define NUM_SAVED 9
         #endif
         "\tpush {r4-r11,lr}\n"
         "\tstr sp, [r0]\n"
         "\tldr sp, [r1]\n"
         "\tpop {r4-r11,lr}\n"
         #if __VFP_FP__
           "\tvpop {d8-d15}\n"
         #endif
         "\tmov r15, lr\n"
