-; EbcLLCALLEX\r
-;\r
-; This function is called to execute an EBC CALLEX instruction. \r
-; This instruction requires that we thunk out to external native\r
-; code. For x64, we switch stacks, copy the arguments to the stack\r
-; and jump to the specified function. \r
-; On return, we restore the stack pointer to its original location.\r
-;\r
-; Destroys no working registers.\r
