Sorry, I replied you lately.

I had used the branch of loki/arm-port with "initial version of ARM port" log.

I am using the maemo chinook scratchbox. GCC version of chinook is 3.4.4.
Fortunately, I succeeded to run arm-port using below source code,

         const int syscall = 0xf0002;
             __asm __volatile (
                    "mov     r0, %0\n"
                    "mov     r1, %1\n"
                    "mov     r7, %2\n"
                    "mov     r2, #0x0\n"
                    "swi     0x00000000\n"
                :   "r" (begin), "r" (end), "r" (syscall)
                :   "r0", "r1", "r7"

Yes, I start to use MacroAssembler based ARM JIT on the branch of
