Thank you both for your answers! That part of type inference was my second question. PHP uses a structure with a union to represent a variable (because a variable can have different types, like a long, a double, a stream, etc..), but often a single variable will only have one type throughout the program (e.g. iterating through $i in a loop). Will LLVM automagically see that we always use the

Hi Nuno, this can be a great project. Some PHP opcodes can be optimised a lot by llvm (like branches or function calls) while others like operations on variables can't be so easy optimized due to the dynamic nature of PHP. For the latest maybe you can use some automatic type inference, like the ones used in languages like Haskell, but this is is a big project and there are also mixed

What's the status of the RSTP - Summer of Code project? Is there code available for trying out and/or testing? I checked the website http://code.google.com/soc/osdl/appinfo.html?csaid=C0F61CA7F642B875 and couldn't find any recent information.

Hi Jim. Thanks for your speedy response. I'm not entirely sure if a JIT is what I'm looking for. I'm basically looking for a dll with an interface that takes a C program as input and compiles and optimizes it to native x86 instructions in an in-memory buffer. I don't want the dll the execute it, and I don't particularly want to translate our expressions into LLVM bitcode

Hi pls help 1/ I run application but it said "Attention: Zend Optimizer not Installed" but I type php -v Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies Why? 2/ ls nfs working except tcp?

Hey folks- If I wanted to distribute my code to users that would run the code on their own machine, how could I go about encrypting the source to run on a user''s machine? PHP has the Zend Encoder among others, I believe. Is there anything similar for Ruby? Jake -- Posted via http://www.ruby-forum.com/.

Hi, I noticed that LLVM had signed up as a mentoring organization for Google's summer of code. LLVM looks like an exciting project that overlaps some of my interests. I would be interested in developing an additional front end for a language it does not currently support (I'm open to what language). I do not know much about what this entails in regards to what LLVM requires from its

Reid, Thanks for the detailed feedback. A value of zero now means zero literal for everything except labels, right? There is kind of a vague reference to this in the 1.0 -> 1.1 section I believe. You might want to make this clearer when talking about values in the body of the document. --> A comment on this: if a value of zero were never used for labels, that would make me happy,

Yes!, particularly if it is in a domain that LLVM isn't known to handle well currently. I'd suggest ocaml/haskell or python/ruby as representatives of the functional and scripting language communities. If you were to do a

Hi, Though there exists lots of researches on parallelizing or scheduling optimization passes, If you open up the time matrices of codegen(llc -time-passes), you'll find that the most time consuming task is actually instruction selection(40~50% of time) instead of optimization passes(10~0%). That's why we're trying to parallelize the (target-independent) instruction selection process

Hi, I'm changing bytecode format a little bit, i.e. for 2 operands Instructions, the original is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 23-16: Operand#1 31-24: Operand#2 My change is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 16: myflag1 17: myflag2 24-18: Operand#1 31-25: Operand#2 I do

So I thought I'd write this down, in case anyone has useful input to it or wants to read up on the decisions later. Currnetly swfdec compiles actions from a flash file into JSScript objects and executes them using the standard Spidermonkey API. While this allows all the niceties that are available with SpiderMonkey (most important: a whole debugging framework with stack inspection etc - see
