Re: java assembler??

Have a look at the following set of tools:


http://jasmin.sourceforge.net - converts ascii version of byte code to a
class file


http://www.neilvandyke.org/jasmin-emacs/ - Emacs plugin for Jasmin, with
syntax highlighting


http://www.angelfire.com/tx4/cus/jasper/ - Jasper converts class files
to Jasmin


http://jakarta.apache.org/bcel/index.html - Bcel contains a byte-code
verifier that produces readable error messages.


and perhaps http://mindprod.com/jgloss/disassembler.html - Some more
java disassemblers


The tools don't quite use the syntax you use, I think, but they work
like a charme. We used them last year in a compiler construction class.


The students produced a Pascal compiler that produced the Jasmin ascii
form of byte code. They used Jasmin to compile that to class files.
Doing that, we obviously needed tools to see what the Java compiler
does, to change that, and to recompile the result. Bcel is very
useful as it gives you better error messages for incorrect byte code.


Hope that helps,
