Appeal No. 97-2466 Page 2
Application No. 08/461,943
DECISION ON APPEAL
This is a decision on the appeal under 35 U.S.C. § 134
from the final rejection of claims 1, 2, 4-9, and 11-18. We
affirm-in-part.
BACKGROUND
The invention at issue in this appeal relates to
optimized compiling. A compiler generally converts a source
program into object code. An optimizing compiler also
eliminates code that is unnecessary for the execution of a
procedure being compiled. Many optimizing compilers, however,
ineffectively process asynchronous events such as program
exceptions. The invention improves the processing of
asynchronous events by defining visibility boundaries in
compiled code of an optimization compiler. The visibility
boundaries are identified by inserting pseudo operations into
an intermediate representation of the source code.
Claim 18, which is representative for our purposes,
follows:
