architecture to be debugged on an existing microprocessor.
The machine code is first converted to high-level source code
that is architecture-independent. The source code is then
compiled and linked to produce an executable load module for
the existing microprocessor. When the load module is executed
by the existing microprocessor, it performs the same
operations that the new microprocessor will perform, thereby
debugging the micro- processor-dependent executable code on
the existing microprocessor.
Claim 1, which is representative for our purposes,
follows:
1. A converting method for converting an
architecture of a program, comprising:
a first step of compiling a first high-level
language source program for a computer of a first
architecture, thereby producing a machine program
for a computer of a second architecture;
a second step of decompiling the machine
program, thereby producing a second high-level
language source program which does not depend on any
architecture; and
a third step of compiling and linking the second
high-level language source program, thereby
producing a first executable load module.
