Hello All, I am looking at exploring what benefits SAFECode has to offer over clang S.A and llvm's instrumentation tools like memory sanitizer and address sanitizer. I could come up with the following that are not provided in ASAN/MSAN/Clang S.A -> dangling pointer error and detection -> crashes in system libraries due to security vulnerabilities. In the process, I wanted to run the

Hi James/Tim, I am trying to add a patterns for SMLALBB I think these two assembly patterns can be reduced to SMLALBB using tablegen. 1) smulbb r2, r3, r2 adds r0, r2, r0 (RdLo) asr r3, r2, #31 adc r1, r3, r1 (RdHi) ==> smlalbb r0, r1, r3, r2 I have added pattern in def SMLALBB : AMulxyI64< ..... as below :- [] modified to ---> [((set GPR:$RdLo,

Hi. I''m just starting out with Rails. I''m thinking of writing a web based PIM, partly as a learning experience, partly because I need one. I''ll be using iCalendar and vCard files for for storage because it will let me sync with PDAs, and use other already available PIMs. What would be the best practice for this? a) At the beginning of a session pull all my vevents

2) For lag in execution time due to floating point operations, it was clearly observed that gcc used floating point instruction FSQRT, where as clang seemed to use emulated function (?) BL SQRT. Note that we used the following flags for both clang as well as gcc compilation. -march=armv7-a -mfloat-abi=softfp -mfpu=vfpv3-d16 -mtune=cortex-a8 Infact, i was surprised to see that even when

I am just considering various different designs for the code emitted by a HLVM and one alluring approach is to make all local variables immutable and replace loops with (tail) recursive functions. This makes it much easier to reason about injected code such as GC checks. However, I am concerned about the performance of the generated code. Specifically, this is likely to result in small

Hello, I am Abhinav Tripathi, B.Tech 3rd Year student from IIT Indore, India. I was looking on the projects ideas page of llvm and saw that I could also propose to work on the SAFECode Open projects. As I found no mailing list on their site, I am sending this message here. Please redirect me to some other list, if required. . I found most of the projects quite alluring as I have been working on a

OK, so for most of my career, I''ve done everything on an hourly rate. Recently somebody kind of pointed out that if you bill by the milestone you can work on multiple projects simultaneously without any ethical problems, so you get increased efficiency. Does anyone have any good advice/URLs/books on how to do cost estimates on a project? I''ve really always kind of avoided the

I see the allure of this, but I think down the road you will discover passing a flag in libvirt XML saying "please use a secure mode" or whatever is a good idea. Even thought it is probably not required to address this specific issue. For example, I don't think ballooning works in secure mode, you w...

I'm starting work on some provisioning tools to simplify plugging in and configuring hard SIP handsets and conference bridges (maybe eventually MPEG-4 PoE video cameras that speak SIP as well). Issue is that I'd like to glean as much information out of the configuration files... but don't want to write a whole new parser to do it (especially not one that understands templates and
