I think gcc just duplicates the block (see tree-eh.c).

Hi, I need the description of LLVM instructions on bitcode file. I can't find it on any document. Reading the code costs much time. Does a description like this exist ? It should look like the JVM Instruction set on the link bellow: http://java.sun.com/docs/books/jvms/second_edition/html/Instructions2.doc.ht ml Thanks for any advise. Quang

Hi, I'm looking for a way to map bitcode to the source code (C/C++) from which it was generated. For example, the Java class file format has an optional LineNumberTable attribute that maps each bytecode instruction to a source code line number: http://java.sun.com/docs/books/jvms/second_edition/html/ClassFile.doc.html#22856 Is there something analogous in the LLVM environment? Thanks,

Now that I've got exceptions working, I'm kind of wondering how to handle the case of nested "try" blocks. Say I have some code that looks like this: try { try { if (test) { // throw something } else { return; } } catch e:Except1 { } catch e:Except2 { } finally { } // more code... } catch e:Except3 { } finally {

I'm trying to figure out how to use virsh (or something else) to list all the IP addresses (or MAC addresses if needed) for each virtual NIC, preferably with it domain affiliation also listed. Is this possible? Thanks, JSR/ -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi All, I am using llvm-2.9 to cross compile to alpha. I know that alpha is in experimental stage, but i can not get even the "Hello World" program to run on it. Here is what happens, the bitcode file for the hello world program is as follow: ; ModuleID = 'hello.bc' target datalayout =

Not sure if this the right place, but I can't seem to subscribe to the rJava mailing list. Sorry for the noise. I have a jar file in the CLASSPATH variable. On running .jinit and checking .jclassPath, i can see the jar file containing the class. Yet when trying to instantaite the class, i get a class not found error. Now If if, create my own vm (see below), and then run .jinit (which will

Hi all, I have a function - let's call it "myfunction". This function is based on some random number generator. Now, once in a while the function will break/crash depending on the random number it generate inside the function. To avoid the problem, what I intend to do is the following: 1. Catch the try-error using class. 2. Redo the function if it returns "try-error" 3.

I would like to see the code of your front end. I started working with llvm-java, since it was what was available. It does not run yet (small compilation issues, almost done), but the design seems fine. It can run (when setup complete) small pieces of Java code, but no real application, since it does not support exception handling (jsr/ret bytecodes) yet,nor garbage collection. Implementing these

Hi, I found that machine dead code elimination, does not respect the calling convention of alpha and eliminates r16, which was set correctly during code generation. I verified it with -print-after-all. Does anybody have a patch for this?

I have just worked with this code. The architecture is fine, and I think that this code should be reused, It needs updating, however, because it does not compile with LLVM 2.1 (I prefer to use a stable version to focus my work, and port to LLVM 2.2 later). I have seen that one incompatibility is that this Java frontend requires C++ with exceptions, but LLVM is compiled with -fno-exceptions. For

Dear developers, Are there any benchmarks for the performance of Java Native Interface (JNI) calls in VMKit? Since VMKit is based on LLVM which can also run C++ code (maybe in the same just-in-time compiler?) I guess calls from Java to C++ and back could be much faster than in Sun's JVM which has extremely slow C++ -> Java callbacks. If this was the case, this would be a big advantage of

Hi there, I am trying to diagnose a performance problem on a Sun T5120 running Solaris 10. I see general poor performance using Java and, in particular, loading classes. I have developed a simple java test that loads all of the classes in a Crystal Reports JAR file (around 7000 classes) which takes much longer on the T5120 (40 secs) than on a Core 2 Duo windows PC (5 secs). I recognise that this
