similar to: [LLVMdev] Get size of operand

Hi, Can we find the size of memory a pointer is pointing to in LLVM. For example type *p = (type *)malloc(sizeof(type)*20); then it should give us size as sizeof(type) * 20. -- Sunil Rathee MTech IIT Delhi Not going along with the crowd can help you stand out in the crowd -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I want to ask is that can we use the information generated by existing passes into a new pass? If yes, then how ? For example -loops gives the natural loop information, so can we use this information into new pass by calling it. -- Sunil Rathee MTech IIT Delhi Not going along with the crowd can help you stand out in the crowd -------------- next part -------------- An HTML attachment was

Sir/Ma'am, I am a MTech student at IIT Bombay, doing my thesis in compiler optimization. I am working on "Profile Based Pointer Analysis to Perform Optimization", and would like to implement the optimization in llvm for performing experiments. When I was trying to build and install the compiler after configuring llvm-gcc I got the following error: gcc: gengtype-lex.c: No such

Hi, I am a student at IIT Kanpur. I am working on Path Profiling, i just came with a need to know about the number of static paths in a program(actually in a function) before it's actually get run. As i saw in PathProfiling.c file in llvm\runtime\libprofile they are just storing the path information at run time and dynamically adding entries for the new path. But i need to know the number of

Hi, I am a Mtech student at IIT,Bombay and presently studying llvm as a part of my Seminar work.Currently,i am writing a simple pass that would detect function pointer call,use and declarations in the src program. I could detect function pointer calls using the getCalledFunction(). However,i am stuck in identifying function pointer declaration and use. is there a way one can distinguish between

Hello Sir, Im trying to test run pbqp register allocator for small C programs. by llc -regalloc=pbqp -debug <bitcode of the file> It is giving me segmentation fault for even very simple programs having loops or if statements.

The simple C code on which im running the allocator is attached. And these are the set of commands. I dont understand ..guess i might be doing something very silly.

Is there a way to get the sizeof a type? Say I've created a struct type without any explicit attribtues, and I want to call malloc() to allocate space for it. Can I get the size as an llvm::Constant* (or other llvm::Value*) given an llvm::StructType* or other llvm::Type*? TIA, -- Rick
