* configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct implementation of the arm backend port to build and pass the current test cases. Tested on armv7 with softfp abi. * lib/jit_disasm.c: Rename and change prototype of static disassemble function as in the arm backend it is required to access state information stored in the jit_state_t object. * check/3to2.tst, check/add.tst: Correct test case code assuming JIT_RO and JIT_RET are the same, and even if they are the same, the logic was incorrect because it must always call jit_retval* to fetch a function call return before any other instruction. The arm backend hash a special condition if jit_retval is not called, because "r0" is not JIT_R0, but is JIT_RET and *also* the first argument for a called function, so JIT_RET must be only used as an argument to jit_retval. * TODO: New file listing important tasks to be resolved.
