...ink also other may find it useful, so I am sending it here, so you can add it somewhere on the web if you will would like to. It is not exactly a publication, rather lecture slides. Title: Languages Used in LLVM During Compilation Date: 30th April 2014 Author: Adam Husar, FIT BUT, ihusar at fit.vutbr.cz Abstract: Presentation deals with intermediate presentations used in LLVM during compilation from a high-level programming language into assembly language. It briefly describes clang's AST, then LLVM IR, and also Selection DAG and Machine Code repesentations. It can be dowloaded here http:...

Dear list... In regards to recent upgrade in www.clamav.net to 0.88.3 and... ...as an example I've used this page to create a process where I can create my own clamav programs/stuff/etc... http://qmail.jms1.net/clamav-upgrade.shtml and so I would go to http://crash.fce.vutbr.cz/crash-hat/4/clamav/ and snag the source rpm that Petr made for Fedora 4. He hasn't updated yet (pretty sure he will soon) as an alternative... how would I do what Petr does and create my own clamav source rpm... I don't think it is that hard yet since I am involving production hardwar...

Hallo! While compiling Icecast (after successfully installing libshout, ogg, vorbis-tools, and libao on a Red Hat 8.0 system) I get the following error which causes the compilation to abort: --- quote: [...] make[2]: Entering directory `/usr/local/programs/icecast/src' source='yp.c' object='yp.o' libtool=no \ depfile='.deps/yp.Po' tmpdepfile='.deps/yp.TPo' \

Hi everyone, I am trying to write a pass, that finds some instructions and replaces them with my intrinsics, but I am having problem understanding, how this should be done. Let's say I have this instruction: %tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28) and i need to read the load's operands and replace it by let's say: %tmp14 = call i32

Hello everyone, we are planning to implement a stronger alias analysis for backend, because e.g. for VLIW architectures, this is our main performance limitation. I would have 2 questions regarding this. I know that backend processes one function at a time, is it somehow possible to do there a whole program analysis, or could you give me some guidelines? Which alias analysis algorithm

Hi, I am newbie for LLVM. I need some help, I want to disassemble ARM binaries and perform some operation on LLVM IR and again back to generate ARM binary from modified ARM LLVM IR. How I can proceed for the same. Any tool or document will be highly appreciated. Thanks and Regards, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello gyus, I am working on a project, where we are trying to create a development environment for new ASIP processor design. Part of this project is a compiler generator, where we would like to generate C compiler from some instruction description. To keep it short, let's say, that in each instruction's semantics is described by some C code. What I would like to do is to compile this

I forgot to mention, that I use LLVM release 2.8, I did not try it with the latest revision, but I expect that I am rather doing something wrong than using non-implemented functions.

Hello, thank you for your answers, in fact, the TCE project is quite similar to our project Lissom (http://www.fit.vutbr.cz/research/view_product.php.en?id=52&notitle=1), I will take a closer look at it. One problem, I was trying to solve was, that I need to declare variables of let's say 5-bit width like 'i5 var', the maximal bit-width may be limited to 64 bits. I need such variables to represent i...

Hello, i need to fold constants, i found that a function ConstantFoldConstantExpression could be used, however I am not able to make it fold anything. Could you please give me some advice, what I am doing wrong?

LLVM version: 2.6 Query context: Automatic generator of LLVM backends. Query: What are canonical rules for initial DAG (generated by LLVM)? Are there any at all? Example: Commutative operations. Are operations like X = 1 + REG automatically transformed into X = REG + 1 ? Because of the nature of our project, we need exact information. Thank you very much. JH

Hello, is there any way I can access CallGraph from immutable pass via getAnalysis? As I understand it, this may not be possible, because immutable pass don't have runOn method and is never actually planned. But I'm not 100% sure how this works, so I don't know if there is some other way. Thanks, Robert Barucak
