similar to: [LLVMdev] Difficulty inserting putchar in IR

I found these lines in the BrainF example: //declare i32 @getchar() getchar_func = cast<Function>(module-> getOrInsertFunction("getchar", IntegerType::getInt32Ty(C), NULL)); //declare i32 @putchar(i32) putchar_func = cast<Function>(module-> getOrInsertFunction("putchar", IntegerType::getInt32Ty(C),

Valery, That's pretty cute actually. Do you want this "brilliant" :) example in the cvs repository? I'd be happy to put it in. Reid.

Here's an idea: how about we take the ModuleMaker, Valery's previous example, and this one and put them all in one "small examples" project? -Chris > Valery A.Khamenya wrote: > >

On second thought, the makefiles don't (easily) allow this do they? You can only build one program per directory. Were you suggesting that you wanted me to move the entire directories under a "small examples" directory? Reid.

Here's my translation of the Fibonacci example into OCaml: open Printf open Llvm let build_fib m = let fibf = define_function "fib" (function_type i32_type [| i32_type |]) m in let bb = builder_at_end (entry_block fibf) in let one = const_int i32_type 1 and two = const_int i32_type 2 in let argx = param fibf 0 in set_value_name "AnArg" argx; let

I am using llvm-2.6 and the ConstProp.cpp file is http://llvm.org/docs/doxygen/html/ConstantProp_8cpp_source.html and the exact error message is: llvm[0]: Compiling ConstantProp.cpp for Release build (PIC) /home/tarun/Desktop/compiler/LLVM/llvm-2.6/include/llvm/Analysis/ConstantFolding.h: In member function ‘virtual bool<unnamed>::ConstantPropagation::runOnFunction(llvm::Function&)’:

The clone llvm:CloneBasicBlock copies the phi function in the replicated basic block from the original basic block. I don't want the copy of phi in relplicated block. For now I am creating .bc file with -O0 option so that it doesn't generate phi function in first place. Is this a good approach or there are some other function available for it.

Hi, I am using alias analysis to determine whether two values are alias or not. But I am not able to figure out the algorithm that is being used to determine May , Must and No Alias.

This is a question worth asking; it's just that not everyone can answer all the time. :) If all you want to do is to follow the SSA def-use chain within a single function, then this is very easy. All you have to do is use

Thanks John, I know how to iterate through def-use chains and I also have realized the need for an algorithm to do the work. But the algorithm I am able to figure out is not linear in time. It wold be a great help if someone suggest me a way to get all basic-block along all path between two instruction. On Wed, May 4, 2011 at 7:00 AM, John Criswell <criswell at illinois.edu> wrote: >

Hi, I am writing a pass for constant propagation using graph restructuring ( code duplication). I am facing following difficulties.. 1) I need to replicate the basic block but without phi function in the replicated block. How can I do this. 2) I need to insert that basic block after and before some particular basic block. Regards Tarun Agrawal -------------- next part -------------- An HTML

Just to be clear, I have to add a function name printf in the module with no body. And I can call the function. This will automatically call the printf function which is defined in the library.
