Hi- I am writing a pass to traverse loops and collect some analysis data and later on come back to transform the IR. In the analysis phase I need to remember statistics regarding every loop in the program. What is the best way to uniquely remember a loop?

Polly is already divided into analysis and transformation passes. However, the interface is currently specific to the needs of polyhedral optimizers. If there is interest to use e.g.

i am organizing my LLVM Passes into an Analysis Pass and a few Optimization Passes, which takes the result from analysis pass to guide their transformations. I found a surprising pass type dependency between the analysis pass and optimization passes. E.g. Analysis-Pass Type Optimization-Pass Type Status in Optimization Pass when adding the Analysis Pass

Can we not run the -insert-edge-profiling and -profile-loader passes at the beginning of the opt? Orthogonal point is, is it worth doing any optimizations when -insert-edge-profiling is specified on command line? -Prashantha -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Alastair Murray Sent: Wednesday, September 19, 2012

I am having problems passing analysis results to transformation passes, so I reduced my testcase into the following bare bone: Pass1: simple FunctionPass, counting functions Pass2: transformation pass, for now, just trying to obtain a reference of Pass1 using AU.getAnalysis<Pass1>() inside its runOnFunction(). When I run it, I get the following runtime error: opt -load

No. Such a target hook does not exist. > I am looking for something similar to TargetInstrInfo::copyRegTpReg but one that creates other types of instructions. It almost sounds like you should be writing a normal optimization pass

Hello LLVM developers, I have a few questions regarding analysis and transformation of Machine IRs. I am writing a scheduling pass that transforms single basic block loops. Details of the pass can be found in an email I sent two weeks ago. http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-August/033808.html I have changed my pass to run before Live Variable Analysis since then. 1, Induction

I see that the well-defined order for transforming a page to HTML is: - Transform the content using the content converter ... - Replace tags I think it should be the other way around. I wrote this plugin that transform {flickr: <url of the photo>} into something like: <div> Foto, caption, etc. </div> Now, because of the order of transformations, the

Hello everyone, I am trying to write a trivial adding metadata transformation pass. I have Test.bc the target on which I want to perform transformations. First, I compile with clang++ my target program and I have my resulting Test.bc. I save it under Test1.bc. As a particular example, I have " %myDimension = alloca %class.ThreeDimension, align 4 ". Second, I apply my pass :

Hi, I have downloaded openssh(http://www.openssh.com/) on my Windows host. Just wanted to know if openssh allows executing a batch script on Windows host. Batch script contains mapping of shares which is required for my scripts. My command run from hpux: $ ssh <windows server> myscript The myscript requires shares to be mapped on login via

Hi,   Could any one please help how I can transform data based on Box-Cox Transformations in R.   Any helps will be much appreciated.   thanks, Kagba [[alternative HTML version deleted]]

Dear, Some analysis (linear regression) can only be done from a vectorized dataset whereas others require a matrix (Mantel tests). I use the two analyses and thus need to format my data in matrix and vector. I spent some time trying to solve the problem and I just gave up. Did anyone knows how to transform a matrix into a vector and back-transform a vector into a matrix? Thanks by

Hi, I'm a student who is going to make a countermeasure for dangling pointers in c for his thesis. I need to make my source transformation using llvm. Nobody in my university already used LLVM. I already read a some documentation about llvm but i'm still lost. Do there exist some " examples/Tutorials" for making small source transformations. Or is there somebody who can help

Hello R helpers! I'm using the avas function form package acepack (called from areg.boot package Hmisc) to estimate automatically transformations of predictors (in this case monotonous) and response. Well, it seems to work quite well, but I have 3 basic questions: - which set of basis functions is used in this procedure? - how do I back transform my estimate (y hat ) to the originasl scale?
