Now, each SSA instruction can be translated into one or a sequence of machine instructions. In order to do this, we must define the stackframe, which is used when calling a method. text/html 2019-08-27T12:30:24+00:00 Anonymous (anonymous@undisclosed.example.com) https://deepjava.org/dev/crosscompiler/backend_ppc/exceptions?rev=1566901824&do=diff Exceptions Terminology * PPC Exception: Exception which are specific to the PPC architecture. * Interrupt: A certain type of a PPC exception, caused by asynchronous events by external hardware. * Java Exception: Exception defined in the Java language specification.
