Here is the partial code: int highIndex = dependency.hdlmGetHighIndex(); int lowIndex = dependency.hdlmGetLowIndex(); for (int i=lowIndex; i <= highIndex; i++) { if ( dependencyDeclaration.hdlmIsRegister(i) || dependencyDeclaration.hdlmIsLatch(i) ) { /* encountered a register other then state variable */ return true; } Object "dependency" is of type "hdlDependency" which is an interface. The hdlmGetHighIndex and hdlmGetLowIndex are methods described in the interface and are implemented in classes that implement the interface. There was one similar loop in the file before line 448, but no error was issued against it. Here is the command line I used and the result: % gcj -v -C --encoding=UTF-8 -CLASSPATH /home/shroff/work hdlFSM.java Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.0.1/specs Configured with: ../configure --with-as=/usr/local/bin/as --with-ld=/usr/local/bin/ld --enable-libgcj Thread model: posix gcc version 3.0.1 /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.0.1/jc1 hdlFSM.java -quiet -dumpbase hdlFSM.java -g1 -version -fencoding=UTF-8 -fencoding=UTF-8 -fCLASSPATH=/home/shroff/work -fsyntax-only -femit-class-files -o /dev/null GNU Java version 3.0.1 (sparc-sun-solaris2.8) compiled by GNU C version 3.0.1. hdlFSM.java: In class `dualsoft.rules.hdlFSM': hdlFSM.java: In method `dualsoft.rules.hdlFSM.checkForPIAndNonStateVariables(java.util.Vector,dualsoft.rules.hdlDeclInterface,dualsoft.rules.hdlDeclInterface)': hdlFSM.java:448: Unreachable statement. for (int i=lowIndex; i <= highIndex; i++) { ^ 1 error Le me know if you want any other information. -- Saurin shroff@transeda.com P.S >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
