(into balance). Do you know how I can<br>> compile the code for preserving Q?<br><br>You've probably got to convince the compiler not to optimise since<br>eliminating those variables is probably one of the simpler things that<br>goes on during optimisation. I'd expect the unoptimised code to have<br>"alloca" instructions inside the function which represent those<br>variables.<br><br>I'm afraid I don't know the javac command-line option to do that<br>though. Your questions may be better answered on a Java list dealing<br>with that compiler.<br><br>> Ok, in the bytecode there is no string "P", "balance" etc. I assume they
are<br>>
preserved in internal globals.<br><br>Could be. Doesn't java use UTF-16 for its strings? If so, I'd be<br>looking for arrays of i16 for my names. Assuming they're there at all,<br>of course (depends on Java API, ABI and possibly optimisations LLVM<br>was able to perform).<br><br>If you post a full .ll file we may be able to say more. Or someone may<br>be along who knows the Java LLVM compiler off the top of their head.<br><br>Cheers.<br><br>Tim.<br><br><br></div> </div> </div> </div></div></div><br>_______________________________________________<br>LLVM Developers mailing list<br><a ymailto="mailto:LLVMdev@cs.uiuc.edu" href="mailto:LLVMdev@cs.uiuc.edu">LLVMdev@cs.uiuc.edu</a> <a href="http://llvm.cs.uiuc.edu/" target="_blank">http://llvm.cs.uiuc.edu</a><br><a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev" target="_blank">http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev</a><br><br><br></div> </div> </div>
