similar to: [LLVMdev] bytecode reader

Hi, I currently write a tool to parse the LLVM bytecode file (.bc file). So I have some very basic questions: - First, about the Abbreviation ID ( "0"=END_BLOCK, "1"=ENTER_SUBBLOCK...): how to read these ID from the file stream ? I mean, I don't know, how many bit length they are. It doesn't exist on the document. - Second, how is the order to read the bytecode ? For

llvm-gcc is the C compiler, but you're trying to compile a C++ file. "@_Znwj" looks like part of a C++ symbol. Try llvm-g++ instead, that should help. - Simon 2008/7/23 Le Anh Quang <anh_quang.le at mailbox.tu-dresden.de>: > Hi, > I have tried to compile a simple cpp file with llvm-gcc.

Hi, but on some other project, they require "configure.lib". What is this one ?

AFAK, the Configuration project does not generate any output. It just patch and generate some required header file.

Hi Jean-Daniel, thank for ur fast answer, i have fixed this error, another function was defined inside llvm source code. So, my only problem now is, I cannot create the file "configure.lib" (belongs to project "Configure"). I can build this project without error, but it didn't generate the lib data ?! Can you build this file ? if yes, I will be very happy if you send it to

Not this one, I have a different error here. One related to hasmap and pair templates. I will check this on my Windows machine later.

Hi Jean-Daniel, Thank I use VC++ 9 (express version). I have also an error in TableGen: The "strtoll" could not be found under win32. Have you fixed it ?

So far, I'm building largely clean too. I had to change which llvmAsmParser it was looking at since it needs to look at the generated file under the win32\AsmParser directory rather than ...\lib\AsmParser where no such file exists. After that, it compiles clean on debug. Working on release now and then I'll check that change in. Quang, do you have flex and bison on your system and in

Quang, you need to set Configure to Utility type. For some reason it gets messed up in the conversion process to VS2008. Go to Configure properties / General and put Utility in Configuration Type. It helped on me. Also some h/cpp files might be dislocated, at least I needed to relocate AsmParser files... Then it should work just fine except some projects recompile excessively for unknonwn

Hi Argiris, It was for example the project TableGen, llvm-dis... I saw it under Properties/Linker/Command Line And the output is also: Linking... Starting pass 1 LINK : fatal error LNK1181: cannot open input file '..\configure\configure\configure.lib' Build log was saved at "file://d:\Studium\Diplom\Download\llvm-2.3\win32\TableGen\Win32\Release\Bui ldLog.htm" TableGen - 1

Hi Chris, Owen Thank for your answers. I have read it before. I mean something different. For example, I read a burst of bytes from a bitcode, which corresponds a LOAD instruction: [0,3,0], it actually means something like "%tmp1 = load i32* @x,align 4" Is there a document, that describes how the information in instructions decoded was ? In the case of JVM, it was described detail,

Hi, I have tried to compile LLVM with Visual C++. Some subprojects work now. Other subprojects require the file "configure.lib". So I tried to compile the project "Configure". It could be built successfully, but the file "configure.lib" is not generated. So, what is the problem here ? Can somebody help me to fix that ? Thanks and regards Quang

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

AFAIK, all LLVM projects have dependency on the configure project but this is only so that some include files are created, no

Hi, I have a question about the "sext..to" instruction. In the document, I found two examples: %x = sext i8 -1 to i16 It means: i8 -1 = 1111 1111 --> 1111 1111 1111 1111 = i16 how can it determinate, that the i16 value %x positive is (65535)? And the second example: %y = sext i1 true to i32 1 --> 1111 1111 1111 1111 1111 1111 1111 1111 In this example, %y is -1 I'm not sure

Thank Duncan, what I actually want, is to implement a simple processor simulator, which can execute LLVM bitcode. So it must deal with the virtual LLVM instruction set. As I compiled a C or C++ program using llvm-gcc or llvm-g++, I have a bitcode file. If a C++ library is used, some functions will be declared inside it, but not defined there (like the @_Znwj). Is it possible to create LLVM IR

Hi, thank for your answer. Is there any document/tutorial about linking bytecode file with libstdc++ avaiable ?
