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, I have a question about type in LLVM. Is the type of any instruction's parameter always determinate? E.g. an instruction with OPCODE %tmp = OPCODE X, Y which has two parameters X, Y. So, is there the case, that type of X or Y is unclear? Thanks for any advice Quang

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

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 have tried to compile a simple cpp file with llvm-gcc. I have attached the assemble file here. I see a weird thing there. There are some call instructions, they call the function "@_Znwj". But this function was only declared in the file, there is no definition of it. So, how can it work, if this function is "empty" ? Thanks for any advice. Quang -------------- next

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
