Hi, I have a doubt regarding *getAnalysisUsage.* My assumption is that, as analysis passes will not change the IR, all the passes required by an analysis pass should be preserved. Say, I have an analysis pass which requires another analysis pass called *SomeAnalysis* and I have not added *AU.addPreserved<SomeAnalysis>() *to my pass. Would the pass manager still considers the *SomeAnlaysis *as preserved? -- Regards, DTharun -------------- next part -------------- An HTML attachment was scrubbed...

...d like to code a function for it. My problem: I would like to read in data from a file in my current working dir. so my code would look like: myanalysis <- function(sample, samplenr){ sample.samplenr <- read.geodata("sample.samplenr", arg, arg etc.) sample.samplenr.results <- someanalysis(sample.samplenr) } problem is that charater values aren't interpretated as they should. Any tips and tricks? This should be fairly simple but I just can't find any reference to it. Most input values in functions in R are numeric or are strings to be interpretated with bolean statements...

Hi everyone, I'm adding loop profiling to LLVM built-in profiler. I'm just wondering in a class that's not a pass, such as ProfileInfoLoader, how can I get information produced by passes such as LoopInfo and DominatorTree? In other words, ProfileInfoLoader is not a pass, so it can't call AnalysisUsage::addRequired and AnalysisUsage::getAnalysisUsage directly. Then how can it know
