Pankaj, I encourage you to read Chris's excellent blog entry on type system @ http://blog.llvm.org/2011/11/llvm-30-type-system-rewrite.html - Devang On Dec 6, 2011, at 3:54 AM, Pankaj Gode wrote: > Hi All, > > While collecting type information for "anonymous types", I had below observation. > > For the example with anonymous types, given below > struct test

Hey Devang, Thanks for the assist, I'm trying to extract a signature which uniquely identifies a block of code.... this is required for a project I am doing. The no of data structures is one of the identifying features of this signature.

Hi I was having just one more problem. I would like to find these datastructures/ primitive types etc inside a block, however the valuesymbol table is available only at a functional level. What can I do so as to get the number + type of datastructs(eg. arrays etc) inside a single block? Thanks Nipun On Fri, Oct 31, 2008 at 12:05 PM, Devang Patel <dpatel at apple.com> wrote: > Hi

How do you define a data structure for this purpose? Do you mean individual data types like structs or arrays? Or higher-level "logical" structures like lists, trees, or hash tables? The former is obviously easier but even the latter is possible, in some cases. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On

Right now I am writing passes just to look for arrays & structs I am trying to identify the array by parsing the memory description(use regex's) ex./ { [20 x i8], i32 } *- for a struct. is a structure with a character array of size 20 and an integer. I'm not sure if llvm provides an easier way to do this? The type id for most arrays comes out to be a pointer rather than an array, its

Evan, The problem is that I do not know the type of a target function at compile time. If you consider my code example, I don't know the type of 'i' until runtime (in fact, I can't even know a possible range of types 'i' may assume). Thanks, - Slava.

Hello, I'm updating a legacy code using LLVM 2.5 where it has an iteration through a Module's TypeSymbolTable to process each StructType. In LLVM 3.4, TypeSymbolTable has been removed. I can only find the LLVMContextImpl instance of a Module's LLVMContext which has AnonStructTypes and NamedStructTypes two maps. However, LLVMContextImpl is an opaque class which cannot be directly

Hi Chris, > 3. Clang/dragonegg need to adapt to the new API (help appreciated!) what needs to be done exactly? Ciao, Duncan.

Hi all, I am working on my Master's project in security and I am trying to iterate over the argument list of the function. Basically I need to do following things : 1. Check data type of each argument of the argument list of the function. 2. Based on its data type like character array or integer array, pointer, int, char, take different action. 3. I have added following code to check its

Hello, I found some source code using llvm 2.5 that has a call to Module::getTypeName(Type*), which I can't find it anymore in llvm newer than 3.3, so how can I get the name of a type(e.g a user-defined structure) if we have Type* of that ? Besides, I checked that old llvm maintains a TypeSymbolTable that enabled type name look-up, so what's the replacement and mechanism of it in the

Hi All, I've noticed the union type in the language manual [1] but it seems it's not used too much. According to the manual, the code: union { int a; double b; } a; Could be compiled to: %union.anon = type union { i32, double } @a = common global %union.anon zeroinitializer, align 8 ; <%union.anon*> [#uses=0] But when I try to assemble it, I get: $ llvm-as union.ll

Hi All,   I was searching for, extracting information about 'typedefed struct types' from 'module'. I have 'struct' typedefed in a .h file. I try to use this structure instance inside a function.   My .ll file rightly defines this type in the beginning so that it can be used later. (for example below) %struct.DEBLOCK_UNIT = type { i8*, i8*, i8*, i8, i32, i32,

Hi, In my project, there is an rhtml page with an embedded SVG file. In my javascript functions, I can find an object by id inside the SVG file with the following: ObjectInSVG = top.document.embeds[0].getSVGDocument().getElementById("rect"); Now, I want to use Ajax methods, like link_to_remote, in the rhtml page to manipulate the SVG objects. The problem is that link_to_remote

Hi, I'm trying to recover the inheritance relations for a class type (so a list of base classes) from a llvm ir file generated via compiling some cpp file using clang. I have access to the TypeSymbolTable and have found the class type I want to know the base classes for in the table. How do I go about extracting this (debug) information? I'm stuck here: if(StructType*
