[LLVMdev] The "scope" of passes
hi all,
i have some thing not so sure about "scope" of llvm passes:
suppose i have a function pass PassF and a BasicBlock analysis pass PassB.
if i want to use the analysis result of PassB for a BasicBlock in PassF, i
think i can create PassB in runOnFunction of PassF, and call runOnBasicBlock
manually to get the result:
PassB pb; //create a PassB
//we also need consider the analysis usage of PassB
pb.runOnBasicBlock(bb); // run PassB on bb manually
.... use the result of pb ......
is there any other better way?
thanks very much

[LLVMdev] BasicBlock back()
Hello,
I am a beginner of LLVM. I am trying to move among the instructions of a
BasicBlock and I cannot. In this particular example, I try to get the
previous instruction of the end instruction. I am trying 2 methods:
1. I have the following sequence of code:
bool patternDC::runOnBasicBlock(BasicBlock &BB) {
...
if (BB.getTerminator())
{
Instruction* current = BB.getTerminator();
errs() << "\n LAST: "<<*current<<"\n";
Instruction* prev = &BB.back();

[LLVMdev] The "scope" of passes
...ckPass
will be re-run, even if it was run previously and not invalidated.
Plus, you can always write a BasicBlockPass *and* a FunctionPass that
reuse the same code. For example, you could structure your code this way:
classname::analyzeBasicBlock (BasicBlock & BB) {
...
}
BBClassName::runOnBasicBlock (BasicBlock & BB) {
analyzeBasicBlock (BB):
}
FuncClassName::runOnFunction (Function & F) {
for each basic block in F {
analyzeBasicBlock (BB)
}
}
The you either use the BasicBlockPass or FunctionPass depending upon
what your needs are.

[LLVMdev] Basic Block API
Hi,
Is there an API for getting (within a basic block pass) the number of basic
block in the program ?
Thanks.

[LLVMdev] Basic Block API
...ware. You will probably need to write code that does
this for you.
One place to put the code would be in the doInitialization() method of
the BasicBlockPass that you're writing. However, I'm not sure if the
count would be accurate; other passes could invalidate the information
before the runOnBasicBlock() method is called by the PassManager.
Another method is to write a separate ModulePass that counts the number
of basic blocks. Your pass could list it as a prerequisite, and the
PassManager would automatically run this separate ModulePass for you.

Hello, I am getting same opt Stack dump error frequently as well. Also trying to
access basic blocks in runOnBasicBlock(BasicBlock &BB). This is at the 4th line
with errs():
Instruction* current = BB.getTerminator();
errs() << "\n last: "<<*current<<"\n";
Instruction* prev = current->getPrevNode();
errs()<<*prev<<"\n";
What can be the cause?

your question is too vague for anyone to be able to help you. Add details,
for example provide the code for your pass.
