hi all
I add a dummy parameter before m_method,
such as gen_call_vm(cs_put_sfield, rt_helper_putstatic,0, klass,
fieldOp.fld,NULL, m_method, m_pc);
instead of the original
gen_call_vm(cs_put_sfield, rt_helper_putstatic,0, klass,
fieldOp.fld,m_method, m_pc);
then, I got the right method name in the runtime routine to recode the access
history.
However, i donot known the reason. Who can explain?
