It is possible that the side effect of debugging verifications (e.g. assert() statements, etc) have side effects on the state of caches.

Any ideas ? This seems to be a bug. You're lucky; it happens in the sablevm-debeug version. Why don't you try to trace the bug using gdb (or ddd if it works on your platform?). You should certainly file a bug report with an appropriate *minimal* ".jar" file causing the error. Thanks!

Hi, The switched version of vm with debugging disabled fails to run on the simplest hello program. When I run configure and rebuild with enable-debugging-features the vm runs correctly (and no other changes). Any pointers ? Another thing I found was that with the non-debug versions I can invoke as following (the whole benchmark is in the .jar file) sablevm-direct -c "bm.jar" x.y.a.b.main -x 10 and everything is fine. But if I do the same for sablevm-debug I get java.lang.ClassNotFoundException : x.y.a.b.main Why ? Any ideas ? Thanks. -Gunda _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus |

pc=pc->addr is a branch right ? (an indirect one though). Maybe this is a terminology problem, but I thought if a processor changes execution path it is generally considered a branch (either due to a br instruction or due to moving a value directly into the pc). Where can I get hold of Chapter 2 of your thesis ? Thanks. -Gunda >From: "Etienne M.

SPECIAL instructions are *special* instructions that do not participate in inline-threading. They are instructions like the special PREPARE_METHOD which is a handler used to lazily prepare a method, etc. This sould become clearer once you have read chapter 2 of my thesis. Among other special instructions are "slow preparation" instructions [e.g. the version of GETSTATIC which does class initialization if necessary].

There's no need to flag GOTO (and other similar end-of-basic-block instructions) specially, as basic blocks are not computed based on this flag; they're computed based on the type of instruction.

Sorry, another question. In file constants.h you have /* interpreter flags */ #define SVM_INTRP_FLAG_UNUSED 0 #define SVM_INTRP_FLAG_SPECIAL 1 #define SVM_INTRP_FLAG_INLINEABLE 2 #define SVM_INTRP_FLAG_CONTAINS_BRANCH_OR_CALL 3 The meaning of _UNUSED, _INLINEABLE and _BRANCH_OR_CALL seems obvious. What is _SPECIAL ? Is it inlinebale or not ? Thanks. -Gunda >From: "Etienne M.

Thanks for the links. In files instructions.m4.c you have /* ---------------------------------------------------------------------- GOTO ---------------------------------------------------------------------- */ m4svm_instruction_head (GOTO, SVM_INTRP_FLAG_INLINEABLE, 2); pc = pc->addr; m4svm_instruction_tail (); Since GOTO changes the flow of control shouldn't that be flagged as _CONTAINS_BRANCH_OR_CALL ?

Cool. Now for the inline-threading to work on ARM, I did look at the post on the IA-64. I will try it out in the next few days and let you know. You had mentioned about running java programs which exercises all the byte codes. Is there a benchmark/example java program which has the all the byte-codes ? Thanks. -Gunda >From: "Etienne M.

Hi Etienne, In a previous posting you had the following to say on flushing strategy. Here are some more ideas. Currently you have _svmf_flush(_svmt_word *pword). This granularity is very inefficient for many present generation architecture implementations. The next best granularity would be the cache line. The best would would to do code generations for a "block" and then just call the iflush with a pointer and the length. The iflush can be tuned to a particular architecture (or more precisely an implementaion of the architecture). With cache sizes increasing (good fractions of a MB to several MB) it will be a bad idea to flush whole caches as this will greatly affect performance. The CPU bandwidth and the Memory bandwidth is increasing with successive generations .... Let's consider the following cases. 1. Implementation with no caches, then obviously iflush will have to do nothing. 2. Implementation with split I and D with no coherency between them. Then in this case one can either do flush on a cache line basis or if the routine figures out that size of code generations is >= cache size then it can just flush the whole caches. 3. Implementation with multi-level caches with unified caches occuring at higher levels. In this case we need only to flush to the first unified level (this will work only for the UP case). 4. MP implications, depending on the coherency of the various cache levels then one will have to invalidate all the other caches and write out the generated code to main memory. 5. For NUMA ?? Bottom-line: I think it is better off to provide iflush with a second size parameter and leave the implementation specfic for a particular architecture implementation. What say you ? Later, -Gunda Hi Grzegorz, You are doing some very interesting work. A simple comment: we will probably need to be ready to fine tune the flushing strategy for specific architectures. Should we act upon the "data" cache or the "instruction" cache, or both, and what is the ideal granularity of this action (single word (or cache line), or general flush), what do we flush (write back buffer only, all entries in the cache, ...). Yep, a lot of fun ahead... The simplest strategy, on the short term, would be a full cache flush ( of both instruction and data caches). As this only happens "once" for each executed method (at the end of method preparation), the simple approach might have no significant impact on the running time, while allowing the inline-threaded engine to work on modern processors. Of course, once we're done with the inline-threaded engine, we will have to attack the multi-processor cache coherency problem... Thanks a lot for this very important work.

Why not this patch? memset() is often a lot faster than loops, as the compiler may know how to optimize specially for it... if so this patch should speed up every new object allocation. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com --- src/libsablevm/gc_copying.c.orig Tue Dec 10 11:51:13 2002 +++ src/libsablevm/gc_copying.c Tue Dec 10 11:51:34 2002 @@ -1054,14 +1054,7 @@ return JNI_ERR; } - { - size_t i; - - for (i = 0; i < instance_size; i++) - { - ((char *) result)[i] = 0; - } - } + memset(result, 0, instance_size); *pinstance = result; |

FYI-
[ I've also submitted this to the bug DB ]
I was trying to run an app and got an exception that looked like this:
java.io.IOException: Pushback buffer is full
at java.io.PushbackReader.unread(PushbackReader.java:319)
at java.io.LineNumberReader.read(LineNumberReader.java:246)
...
This appears to be a bug in LineNumberReader.java, which the
patch below seems to fix.
Thanks,
-Archie

I suggest that you live with the switch and threaded engines for a little time. I'll be improving the portability framework for the inline-threaded engine in January 2003. I'll add the following features: 1- *partly* automatic detection of inlinability of instructions (on a specific architecture/compiler-options. 2- Better separation of inlinability specifications for specific platform/compiler-options. Of course, you can read chapter 2 of my thesis, when I put it online, to get a better idea of the problem. I just don't have time just now to explain all the details. Etienne -- Etienne M.

Thanks Mike for the tip, it worked ! I now have the switched and the direct threaded interpreter working for small programs. I will stress test the vm's in a few days with larger programs. The inlined version still fails. Why ? Any particular area I should look at to solve this problem ? I believe I have the _iflush routine implemented correctly. Any pointers will be appreciated.

This is Great new! It means SableVM executes quite a lot of code. [Stack
traces are computed in Java, so there's quite a lot of things that are running
for the VM to be able to throw an exception with a stack trace on loading a
class through a Java based class loader.]
Now as to why you get an exception, we should investigate. Mainly, you could
add a few System.out.println(...) traces in the class:
gnu.java.lang.SystemClassLoader
in the method "findClass(...)"
This is, of course, located in the sablevm-class-library, in the file:
src/gnu/java/lang/SystemClassLoader.java
You must recompile, and try running SableVM with the modified class library.
It's so much fun when bootstrapping is done, as you can start debugging the Java
code instead of the C code... ;-) [Usually this is much easier to do, as you
have String concatenation, and automatic int->String conversion in Java without
worrying about memory].
I hope this helps.

Etienne,
A little progress but my Hello world program still fails.
I recompiled all the class libraries with jikes 1.15. Now sablevm can't find
the application class.
The invocation was
sable-debug -v HelloAppworld.class.
The java source is
class HelloWorldApp {
public static void main (String args[]) {
System.out.println("Hello World!");
}
}
/* Expected Output:
Hello World!
*/
I did compile the hello.java with jikes 1.15.
Why are we not finding the application class ? Any ideas ?
Thanks.

Newer versions of Jikes are not yet supported (there are known problems with Jikes 1.17 them that need further investigation). As for the class version number, it means that Jikes 1.18 generates bytecode which is not supported by the currently published JVM specification (i.e. second edition)... Etienne -- Etienne M.

Etienne, I think I found the problem. In files class_loader.c at line 305 you are checking for version number of the class file. The Object.class file under ...../java/lang on my machine has a major_version of 47 and a minor_version of 0. With these values the check in the code fails. Don't know the details of this version number. I built the class libraries using jikes 1.18 on a P4/Linux box. What can I do step around this problem ? Thanks. -Gunda >From: "Etienne M.
