Hello All, I have met one may-alias case from llvm's alias analysis. The code snippet is as following: char buf[4]; void test (int idx) { char *a = &buf[3 - idx]; char *b = &buf[idx]; *a = 1; *b = 2; } I can see below output from alias set tracker for above code snippet. Alias sets for function 'test': Alias...

There are function which does have optimization opportunities but because of may-alias memory dependencies sometimes optimization is not effective. May be runtime checks kills the gains of optimization. For such cases aiming to do interprocedural function specialization optimization where in the clone function version no-alias assumption can be assumed and the original function versi...

Hi, The current AliasAnalysis marks may-alias for cases when memory passed as function argument. i.e. void foo(int *A, int *B, int *C) { for (int i=0; i<N; i++) A[i] = B[i] + C[i]; } In the above example, it's may-alias for memory 'A', because 'A' is not known at 'foo' call site...

Hello, I have Asterisk-1.8.3.2, dahdi-linux-complete-2.4.1+2.4.1, and libpri-1.4.11.5 installed and running on a Ubuntu 10.04 server all built from source. Everything is working nicely except one small issue. The CDR records are stored in the CSV file correctly and complete. The MySQL storage is working as it should and is automatically updating all the fields except the CLID field. I have

Hi, I am trying to get the alias info for the following code. The alias analysis returns "MayAlias" for arrays "A" and "B" in both the functions instead of "NoAlias". What passes should I run in opt before the alias analysis pass to get the accurate result? Example: //Note: static and call...

Dear LLVM Developers, My name is Artem Vopilov, I am a student at TU Darmstadt. I am writing to you to ask about Alias Analysis. I am using llvm to analyze alias between variables in programs. I am using Alias Analysis implemented in llvm with command "opt -analyze -aa-eval -print-all-alias-modref-info" and for printing sets of alias "opt -analyze -aa-eval -print-alias-sets". I execute these c...

Hello, I am performing alias analysis toward the following simple code: struct MyStruct { int * f1; int * f2; }; void NOALIAS(void* p, void* q){ } int main() { struct MyStruct s[2]; int a,b; s[0].f1 = &a; s[1].f1 = &b; NOALIAS(s[a].f1, s[b].f2); return 0; } When I use the following command to generate .bc code an...

Hi, Could anyone tell me how exactly do I use "Type Based Alias Analysis"? I compiled the C program with Clang, and verified that there is tbaa metadata in the IR code. But then when I use "opt -tbaa input.c.bc -aa-eval" to check the results, it always gives 100% may aliasing no matter what input. Am I using "tbaa" correctly? Thanks...

Hi all, I have a problem with alias aliasing results returned by the alias set tracker and the alias analysis evaluator. so i call opt tool to run my module with the following options "-anders-aa -aa-eval -print-alias-sets -print-all-alias-modref-info" i use 2 classes to print alias analysis, the AliasSetTracket and Ali...

Thanks, that's a lot more like the output I was expecting. But, I'm now wondering if I'm doing something wrong because the output confuses me. When run on the program: int main() { int a = 5; int* b = &a; int* c = &a; return *b; } I would expect to see either b may alias c or b must alias c. But, it doesn't even appear in the list. Furthermore, I would expect to see **b (may/must) alias *c, but it instead says that this isn't true. Am I not running the right passes (I used -basicaa -anders-aa) or am I misreading things. Results: Function: main: 6 point...
