[LLVMdev] how to use LoopInfo outside of LLVM
...utside of LLVM. Now I need get LoopInfo for a function. I know that if my project were a pass inside LLVM. I can get LoopInfo by "AU.addRequired<LoopInfo>()" and "getAnalysis<LoopInfo>()". Also I know I can get a function pass by "llvm::FunctionPass* dce = llvm::createDeadCodeEliminationPass(); dce->runOnFunction(*func)" outside of LLVM. But I can't figure out a way to get LoopInfo outside of LLVM. Is there any possible way to do it?
Thanks,

Where s_pFunctionPasses is a FunctionPassManager I create when initializing
my program and delete at shutdown. I'm running the CFG simplification one
first in the hope that it will speed up the passes that follow it.

[LLVMdev] Which transform passes to apply?
Hello, I'm a new LLVM user working on a C++ EDSL for image processing. I have
a function, which after applying createInstructionCombiningPass() and
createDeadCodeEliminationPass() looks like:
define void @jitcv_sum_64sf1001(%Matrix* %src, %Matrix* %dst, i32 %len) {
entry:
br label %loop_i
loop_i: ; preds = %loop_i_end,
%entry
%i = phi i32 [ 0, %entry ], [ %increment_i, %loop_i_end ]
%0 = getelementptr inbounds %Matrix* %dst...

Here's some:
http://llvm.org/docs/WritingAnLLVMPass.html#FunctionPass
You can also look in llvm/lib/Transforms/Scalar for runOnFunction ()

There's no right way to determine this. It depends on what you need/
want from your

[LLVMdev] Running a Local Buildbot
We're thinking about running our own buildbot against the upstream llvm
and clang sources. I'm talking to our build folks and seeing what they
can allow. Maybe we can contribute some build slaves to the osuosl
buildbot but I'm not sure.
If we do end up having to run our own buildbot, what's the best way to
integrate that into the upstream web page and status notifier?
Basically,
