I am pleased to discuss probleams with you. :) (Your answer is really helpful to me). If you don't mind I would often like to ask you a question. Thanks, Jin-Gu Kang

Hi renato, First, I really appreciate your answer. :) The IR in an previous e-mail is incomplete so far and I am converting it to various shape. My team members decided to add new types to solve the bitfield's alignment problem. Let's consider your previous examples: struct testChar { char a:3; char b:4; char c:3; char d:2; }; struct testShort { short a:3; short b:4; short c:3;

Hi LLVM members, I have been working to make target independent memory layout for struct type(Aggregate type) in my team. I think that struct type has different memory layouts according to each target system in current LLVM. To implement target dependent concept for struct type, Frist, I have been implementing common type for struct type on bitcode at compilation time using llvm-gcc and then

Dear LLVM members. Hi. I have a question. I woule like to know whether or not a global variable with abstract or opaque type can has initializer (constructor). For example, general assembly code: %struct.test = type { [10 x i8] } @ovm = global %struct.test { [10 x i8] c"ovmtest\00\00\00" } question: %struct.test = type { [10 x i8], opaque } @ovm = global %struct.test { [10 x

Hi LLVMdev members I found something strange in ConstantExpr::replaceUsesOfWithOnConstant() function. in lib/VMCore/Constants.cpp file 2118 if (getOpcode() == Instruction::GetElementPtr) { 2119 SmallVector<Constant*, 8> Indices; 2120 Constant *Pointer = getOperand(0); 2121 Indices.reserve(getNumOperands()-1); 2122 if (Pointer == From) Pointer = To; 2123 2124 for

Hi all I want to know examples of recursive types on LLVM IR. I read a example of basic recursive type on LLVM Programmer's manual. %mylist = type { %mylist*, i32} Are there another examples of recursive types on LLVM IR? and I want to know what the definition of recursive type is on LLVM IR? Thank you, Jin-Gu Kang -------------- next part -------------- An HTML attachment was

> struct T { > struct T (*p)(void); > } t; This testcase also generates infinite recursion when we use llvm-gcc for arm-target. Because return type of function pointer p's is struct type T which has one element, llvm-gcc for arm target calls a function which tries to chang aggregate return type to inner element. (For example, C.HandleAggregateResultAsScalar(Ty); -->

Hi Dan, Do you mind if I ask you what is the target-independent codegen maintenance? I imagine that target-independent codegen interface have to make with target-independent LLVM IR. I'm also interested in target-independent properties on LLVM. :) Thanks, Jin-Gu Kang ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] On Behalf Of

Hi Duncan, I appreciate your kind review. I'd like to help you to build an ARM cross compiler. I built GCC as following. 1. Download "arm-2010.09-50-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2" You can find this file on https://sourcery.mentor.com/sgpp/lite/arm/portal/release1600. (Please click "IA32 GNU/Linux TAR" on Packages.) 2. Extract this file on your linux

Hi Talin, I had a talk in London developer meeting about More Target Independent Bitcode. (You can download the slides from http://llvm.org/devmtg/2011-09-16/) I have been also trying to make bitcode with more higher abstraction level. I made new compilation strategy using more target indepent bitcode as followins, (This didn't consider about Jit or Interpreter like lli) C/C++ source code
