similar to: [LLVMdev] number of static paths

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

I am trying to use the indvars pass on a simple loop but it does not seem to have any effect The sample code i am using is #include <stdio.h> int test (int p); int main(){ int a,b=3; for(a=7;a*a<100;++a){ if(b >3) test(3); b++; } return 1; } int test(int p){ return p; } According to documentation

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. Please tell me where I'm going wrong. -- Regards, Smriti Jaiswal MTech Dept of Computer Science and Engg, IIT Kanpur -------------- next part --------------

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. Please help *Commands:* clang -emit-llvm -c test.c -o test.bc opt -mem2reg test.bc -o testssa.bc llc -regalloc=pbqp testssa.bc On Mon, Aug 12, 2013 at 7:59 AM, David Blaikie <dblaikie at gmail.com> wrote: > > > >

Hello, I was trying to extract out the IR for some CELLBE code. However i was not able to compile with llvm-gcc. Has someone who has tried this shed some light on the changes required to use llvm-gcc instead of gcc or xlc. A simple replacement of gcc with llvm-gcc -emit-llvm -S or marking $CC as llvm-gcc in the makefile did not work for me. I am using the standard makefile format supplied

Hello, I wanted to do some speculative execution on a loop for which I require some data storage structure for book keeping. The exact structure of this storage buffer can only be determined after loop analysis. Is there a clean way to add this new structure to the module. Since this structure is to be used for each loop iteration I do not want to allocate it inside the loop. A second

Many compilers clone loops and use dynamic checks to enforce invariants in one copy of the loop. Is this intended to be similar to that style of approach? -Chris > > About me: > > I am a final

Hello, I was trying to get the loop info in a module pass to be able to iterate over the loops int the module itself. Since my pass requires to make module level changes including adding new types to module hence a looppass cannot be used here. I am getting the following error on running opt. opt: /root/llvm-2.4/include/llvm/PassAnalysisSupport.h:199: AnalysisType&

This sounds like a great idea. LLVM definitely lacks some profile-driven optimizations. -- With best

Hi again everyone... After following the "Writing an LLVM Pass" tutorial using LLVM 2.5, there is a part that states that: "This makefile specifies that all of the .cpp files in the current directory are to be compiled and linked together into a Debug/lib/Hello.so shared object that can be dynamically loaded by the opt or bugpoint tools via their -load options."

Hi, I was wondering how to add header files to code in LLVM. I am trying to create a small profiler to track the actual time spent in functions. For this i am adding call to clock() in the C code of the given program. However this will require adding the file time.h to C code. Can some tell me a way to do so. I have tried using Module.addLibrary("time.h"); but this doesn't seem

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 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
