-/****************** function asm_call_jit_compiler *****************************
-* *
-* Invokes the compiler for untranslated JavaVM methods. *
-* What this method does: *
-* - save args and LR *
-* - fire up jit_compile (pass methodinfo pointer) *
-* - try to find out where to write back the new method pointer *
-* - restore args and LR *
-* - check for exceptions *
-* - eventually write back new method pointer *
-* - call jit code (wich will then return to caller) *
-* *
-* These methods can call us: codegen_compilerstub & asm_calljavafunction *
-* ATTENTION: use REG_ITMP1 to pass methodinfo pointer to me! *
