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)
{

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

Fault while using AAResultsWrapperPass in LLVM 5.0.1
...ss{
AliasAnalysis *AA;
void getAnalysisUsage(AnalysisUsage &AU) const override {
AU.addRequired<AAResultsWrapperPass>();
}
.........
}
bool Timer::runOnFunction(Function &F)
{
LLVMContext &C = F.getContext();
AA = &getAnalysis<AAResultsWrapperPass>(F).getAAResults();
.....
}
When the Timer pass is registered by the following code:
char CPI::ID = 0;
static RegisterPass<CPI> X("cpi", "code pointer integrity Pass");
The test code can be compiled successfully by the following command:
comp_1:
clang -O0 -emit-llvm test.c -c -o test_clan...

Aliasing of pointers from different address spaces
Hi, Elena,
You're correct. We do assume that pointers in different address spaces
can alias.
Targets can add their own AA pass into the AA query chain, and one of
the things such analysis passes can do account for target-specific
knowledge of address-space semantics. For example, see
lib/Target/AMDGPU/AMDGPUAliasAnalysis.cpp

Aliasing of pointers from different address spaces
Hi,
Can I configure address spaces aliasing for my specific target?
I found this discussion (https://groups.google.com/forum/#!topic/llvm-dev/0ZbzzN6t05o) , where James says "pointers in different address spaces cannot alias",
but it is not what I see in the code.
I looked for a way to customize address spaces separation in Target, but I can't find.

llvm 3.9 Alias Analysis result for function's by-ref arguments
Hi,
I'm writing an analysis pass which is supposed to find instructions in a function that modify function's by-ref arguments. For that I'm using llvm AliasAnalysis pass, particularly querying for ModRef info for instructions and function arguments, to see if a given instruction modifies a given argument. However, for functions with more than one by-ref argument, I get strange
