Hi, I'm trying to detect if a basicblock is part of a loop or not. I tried the llvm::LoopInfo like that (http://llvm.org/docs/doxygen/html/classllvm_1_1LoopInfo.html#a4abca289c73cd09487e05d11d9f7d877): LoopInfo *loop = new LoopInfo(); bool isLoop = loop->getLoopFor(myBB); // getLoopFor - Return the inner most loop that BB lives in. If a basic block is in no loop (for example the entry node), null is returned. See doxygen But getLoopFor() always return me NULL even if my basicblock is inside a for loop... I tried this: http://comments.gmane.org/gmane.comp.compile...

...I then set up a couple of indicators and the following model: myATR <- function(x) ATR(HLC(x))[,'atr'] mySMI <- function(x) SMI(HLC(x))[,'SMI'] myADX <- function(x) ADX(HLC(x))[,'ADX'] myAroon <- function(x) aroon(x[,c('High','Low')])$oscillator myBB <- function(x) BBands(HLC(x))[,'pctB'] myChaikinVol<-function(x)Delt(chaikinVolatility(x[,c("High","Low")]))[,1] myCLV <- function(x) EMA(CLV(HLC(x)))[,1] myMACD <- function(x) MACD(Cl(x))[,2] mySAR <- function(x) SAR(x[,c('High','Close')])...

Hi Reid, Is this design supposed to be able to cope with asynchronous exceptions? I am having trouble imagining how this would work without adding the ability to associate landing pads with scopes in LLVM IR.

Hi, I have a couple of questions about MachineBasicBlocks: - If I have a pointer to an MBB, is there an easy way to find which block that precedes it in the MachineFunction blocks list? (without iterating through all of the MF's basic blocks) - Does LLVM make any effort to ensure that MBB's predecessors and successors lists are semantically correct? For example, what happens if an MBB
