similar to: [LLVMdev] Iterate through a Module's StructTypes

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

Dear Rafael, Thank you for your answer. The verbose mode -v shows that clang uses the old ld in /usr/bin while I install the gold in /usr/local/bin.

Maybe all that you have to do is $ export PATH=/usr/local/bin:$PATH Cheers,

Several people on this list have reported issues with the linker regarding a named StructType instance with the same name in two different modules being resolved into two StructTypes with different names due to StructType:: setName(…) collision behavior. Looking at BitcodeReader::ParseTypeTableBody(…), I don't see use of LLVMContextImpl::NamedStructTypes or of Module::getTypeByName(…). Nor do

Hi, LLVM community, I found an issue in my using scenario. We deliberately parse a bitcode file twice. It contains a named struct type. eg. %struct.cmd = type { float, float, float, float, float, i32 }. In the second module->dump, %struct.cmd becomes %struct.cmd0. my code is simplified like this. int main() { llvm::LLVMContext &llvmCtx = llvm::getGlobalContext(); string ErrMsg;

Hi all, I 'd like to fetch a list of structures, and found that it could be done via LLVMContextImpl *pImpl = Context.pImpl; pImpl->AnonStructTypes This however needs the inclusion of LLVMContextImpl.h, which is not contained in the includes dir, but in the lib/IR dir (next to the .cpp files) and is not installed under /usr/local/include... Whats the reason for this? Isn't it

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

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

Hi All,   While collecting type information for "anonymous types", I had below observation.   For the example with anonymous types, given below struct test {   struct {     union {       Char a[4];     };   };   struct {     int b;     char c;   }; };   LLVM 2.6 defines the types as %struct.anon1 = type { %union.anon0} %struct.anon2 = type { i32, i8} %struct.test = type {

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.

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
