| | | | | | | | | | | | | | | fact "profitable" to do so. This makes compactification "free" for small programs (ie, it is completely disabled) and even helps large programs by not having to encode pointless compactification planes. On 176.gcc, this saves 50K from the bytecode file, which is, alas only a couple percent.
