ScalarEvolution in a ModulePass
...alarEvolution along with several
other analyses. After some debugging, it looks to me like
ScalarEvolutionWrapperPass does not handle memory correctly for this case.
Here's my current understanding of the problem.
ScalarEvolutionWrapperPass maintains a unique_ptr to a ScalarEvolution.
Calling getSE() dereferences this pointer. Meanwhile runOnFunction()
resets the pointer to point to a new ScalarEvolution. As a result,
runOnFunction destructs and frees any ScalarEvolution the unique_ptr
pointed to before.
The ModulePass I'm working on uses ScalarEvolution and several other
analysis Func...

Polly Dependency Analysis in MyPass
Hello,
I need to analyze dependencies in my llvm ir by using polly. i created a
new pass called mypass there i added polly dependency analysis pass but
when i execute this pass in gdb i get no data.
Why is that so?
My code is follows;
namespace {
struct mypass : public FunctionPass {
static char ID;
mypass() : FunctionPass(ID) {
}
virtual bool runOnFunction(Function &F)
{

How do you compile the code? Within the Polly subdirectory using CMake?
How do you run your pass. Using "opt -mypass inputfile.ll"?

Confusing ERROR with LoopAccessLegacyAnalysis: Pass 'Unnamed pass: implement Pass::getPassName()' is not initialized.
...pAccessLegacyAnalysis.
Therefore, I implement the following code based on LLVM 9.0.0:
=====================================================================
bool LoopInformationCollect::runOnLoop(Loop *L, LPPassManager &)
{
auto &SE = getAnalysis<ScalarEvolutionWrapperPass>().getSE();
auto &LI = getAnalysis<LoopInfoWrapperPass>().getLoopInfo();
// auto *LAA = &getAnalysis<LoopAccessLegacyAnalysis>();
if (Loop_id.find(L)==Loop_id.end()) // traverse instructions in the block assign instruction ID
{
Loop_id[L] = ++Loop_Counter;
