...s a tool to help monitor how data flows from its inputs (sources) to its outputs (sinks). This has applications from a privacy/security perspective in that one can audit how a sensitive data item is used within a program and ensure it isn't exiting the program anywhere it shouldn't be. An ASPLOS paper from a few years ago discusses this problem and a solution based on dynamic binary instrumentation using QEMU: http://www.cs.ucsb.edu/~sherwood/pubs/ASPLOS-08-systemtomography.pdf Among other things, I hope to address a number of deficiencies of the tool described by that paper, in terms o...

So I have elaborated this time. More details can also be found in http://www.cs.utexas.edu/users/mckinley/papers/asplos-1994.pdf. Thanks Good time...

Could you maybe give some example use cases?

Hi, I have been away from the list for a while, so do apologize in advance if the topic is slightly off topic here. I have started a hobby project to create a virtual OS library (jos). The idea was to create a set of C API's for operating system specific tasks i.e. File IO, threading and etc. For example: typedef jos_handle jos_thread; jos_thread jos_thread_create(...); void

Hello, We have a publication in ASPLOS 2012 that uses the LLVM infrastructure. Is it possible to add this to the publications web page: http://llvm.org/pubs/ ?

Hi all, This is a GSoC 2013 proposal for LLVM project. Please see the formatted version at here: http://pacman.cs.tsinghua.edu.cn/~liuml07/files/gsoc2013-proposal-program-slicing.pdf Program slicing has been used in many applications, the criteria of which is a pair of statement and variables. I would like to write an inter-procedural program slicing pass in LLVM, which is able to calculate C

Your final proposal should cite other applications that use (or could benefit from) dynamic slicing. Our ASPLOS 2013 paper would be an example, but you should look for and cite several papers about several different applications from several different groups. Industry groups would be a plus. Saying that one or two people use dynamic slicing isn't all that convincing; saying that x different groups...

Hi, I am starting a thread to discuss the design of DataFlowSanitizer, a compiler instrumentation based analysis tool which I am hoping to bring into LLVM. As a starting point, I have included the current version of the design document below. Comments are appreciated. Thanks, Peter DataFlowSanitizer Design Document ********************************* This document sets out the design for

I will be glad if someone mentors me...
