Hi Folks -- Let me go ahead and pose a question similar to the one Joachim poses below. I too am trying to evaluate whether LLVM will be of use to me in building a compiler and garbage collection mechanism for a byte code vm that I have built. Although there are multiple types of code that can be created with this system, all of them eventually translate to execution of one or more of these

...ble slowdowns. I'd imagine that if your asm is sufficiently restricted, such as not needing to worry about arithmetic flags, the x87 FPU stack, or arbitrary control flow, then it should be easy to do without introducing any slowdowns.

Hi -- I'm still very much a newbie with llvm, but am looking (hopefully) to use it to compile into native intel code a set of source that is a combination of byte codes for my own custom vm and intel code that has been coded in assembly language directly. In an earlier exchange, I already discovered that llvm does not do any optimizations on intel assembly language code. This would be an

Curious as to whether any work is in progress on this? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20101202/0ae5d181/attachment.html>

Hi Everyone -- I'm planning on using LLVM to add some optimizing compiling capability to a Byte-Code driven virtual machine that is part of my foundation platform for a series of tool products I am building. I'm still pretty new to this whole arena and am in particular curious about one important aspect: It strikes me that the more optimizations applied to code (whether at the source

Hi -- I'm wondering if some of you old hands might offer me some guidance. I've been working for some time with a virtual machine platform that is based loosely on the instruction set of a Forth hardware processor that Charles Moore designed sometime back. He used what he called a "MISC" or "Minimal Instruction Set Computer" and the original instruction set I was

Wondering if you've gotten any further answering the question you pose below? I also am interested in being able to generate a JVM backend, but not departing, as you are, from coding in java itself, but rather as a means to integrate my own custom vm with Java and be able to produce and consume java code easily from my custom environment. Just curios if you made any progress answering this
