[LLVMdev] Instruction->mayReadFromMemory

[Silken Tiger]

Hi

I am currently trying to schedule instructions with my own algorithm. For that 
i need to get the data dependency between the instructions. So currently i am 
dooing s.t. like:
for(BasicBlock::iterator j=B.begin(),bbe=B.end();j!=bbe;++j) {
          InstructionList.push_back(j);
          if (const AllocaInst *AI = dyn_cast<AllocaInst>(j)) {
                        ValueList.push_back(AI);
          } else if(PHINode *PHI=dyn_cast<PHINode>(j)) {
                        ValueList.push_back(PHI);
          } else if(GetElementPtrInst *GEPI= dyn_cast<GetElementPtrInst>(j)) {   
                        ValueList.push_back(GEPI);
          };
};
To find the first instructions which are not depending on others results. So 
far it seems to be working but i am missing instructions like:
%tmp.1 = seteq int %argc, 2             ; <bool> [#uses=1]
There seems only an function like llvm::Instruction::mayWriteToMemory 
but nothing like llvm::Instruction::mayReadFromMemory or s.t. with similiar 
functionality?

Or else: if there is an even easier way to get the non data depending 
instruction from a block i missed, i would be also happy.

Thanks
S.T.
