similar to: [LLVMdev] What meaning is the argument?

I started using the AliasSetTracker, but I have a problem. I am using -basicaa -anders-aa and optimizations are enabled for llvm-gcc and llvm-ld. I use an instruction visitor to populate the alias set tracker, but two pointers end up in different alias sets. While investigating this I notice at one point that if I call: bool New = false; AliasSet &X = AST->getAliasSetForPointer(Pointer,

Hi folks, Moving the discussion to llvm.dev. None of the changes we talked earlier help. Find attached the C source code that you can use to reproduce the issue. clang --target=aarch64-linux-gnu -c -mcpu=cortex-a57 -Ofast -fno-math-errno test.c -S -o test.s -mllvm -debug-only=licm LICM hoisting to while.body.lr.ph: %21 = load double** %arrayidx8, align 8, !tbaa !5 LICM hoisting to

Can you send me actual LLVM IR or a preprocessed source from using -E? I don't have a machine handy that has headers that target that arch.

Which one? I'm not sure from your description that this is a chaining issue. PartialAlias doesn't chain and isn't supposed to, it's a final answer just like NoAlias and

Oh, sorry, i didn't rebase it when i changed the fix, you would have had to apply the first on top of the second.

Hi, When I compile httpd-2.0, llvmgcc reports many struct types and macros undeclared, but gnu-gcc can compile httpd-2.0 completely.

The llvm I using is llvm-1.2, its cfrontend should be based on gcc-3.4, the system I using is RedHat Linux 9.0, I desire to compile httpd-2.0.51.

Yes. I've attached an updated patch that does the following: 1. Fixes the partialalias of globals/arguments 2. Enables partialalias for cases where nothing has been unified to a global/argument 3. Fixes that select was unifying the condition to the other pieces (the condition does not need to be processed :P). This was causing unnecessary aliasing. 4. Adds a regression test to
