Hi, dear LLVMers I am Qiuping Yi. I am interested in John's SoC project idea, developing Clang's support for detecting undefined behaviors in C/C++, and hope John to be my mentor. I wish to implement detecting some undefined behaivors ranging from easy (such as detecting divide by zero) to rather troublesome ones (such as detecting references to out-of-scope automatic variables). I

Is anyone interested in a SoC project to further develop Clang's support for detecting undefined behaviors in C/C++? This is actually a collection of many smaller projects ranging from very easy (detecting divide by zero) to rather nasty (detecting references to out-of-scope automatic variables). If someone does this, I'm happy to help mentor, provide test cases, etc. If done well,

WUA_table<-WUA.df[,2:dim(WUA.df)[2]] WUA_discharge<-WUA.df[,1] colour_scheme<-palette(rainbow(dim(WUA_table)[2])) # Main scatterplot p1 <- ggplot(NULL, aes(WUA_discharge,WUA_table)) + geom_line() + scale_color_manual(values=colour_scheme)+ scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0)) + expand_limits(y = c(min(WUA_table) -

I know pc-lint is working fine on detecting some nasty coding fault. But is it illegal implement it in clang? And also there is so much other tools for code analyze:) 2010/3/26, yiqiuping1986 <yiqiuping1986 at 126.com>: > 呵呵，不急，还有一学期的时间。 > > > 2010-03-26 > > > > yiqiuping1986 > > > > 发件人： 罗勇刚(Yonggang Luo) > 发送时间： 2010-03-26 15:05:33 > 收件人：

Hi,all: My name is Wei Wu and I would like to participate in Google Summer of Code 2011.I'm willing to improve LLVM's support for profile information,follow Bob Wilson's proposal[1].After read his proposal I have some questions below: 1.Is the "__builtin_expect" works now and how to use it? I have searched llvm's trunk and found it in two files

Hi, I intend to participate in Google's Summer of Code this year, so I'd like to bounce another idea around to see what you guys think. (I posted a similar message to cfe-dev just now.) Be warned: this will shock you. It may even horrify you. 1. Implement a 16-bit x86 backend. (*Chris recoils in horror*) Yeah, I know 16-bit x86 is dead, but I find it interesting for historical purposes

Hi, everybody! My name is Qiuping Yi, and I am a grade-two master student of Institute of Software Chinese Academy of Sciences, Beijing, China. I know LLVM is listed as one of the mentoring organisation for the Google summer of code this year. Last year I began to touch LLVM, and now relatively familiar with its soucecode. I major in program analysis and verification, and pay close attention to

Hi, I have server with multiple virtual domains and this server also accepts mail for the local domain. I'm using postfix and have the following setup for a virtual sales at domain.com mapped to custsales at localhost I was wondering if there is a way to login with the virtual email address, for example sales at domain.com? I would also like to still be able to login with the local user

Hello LLVMers (in particular, LLVMers interested in GSoC), Since people seem interested in GSoC project ideas, here is one that might not be totally obvious -- work on LLVM's testing infrastructure! :) I have been working hard on modernizing our nightly test performance monitoring software, but there is a lot more work to be done. As LLVM developers, we rely on this software for tracking

Hi Daniel, I'm an interested student in that idea I enjoy building web apps and I have good experience. I've worked with PHP, Javascript (Jquery, Dojo, ...), Java (JSF, Struts, ...), and some databases (MySQL, PostgreSQL, ...) ... for more than 7 years. I graduated in 2005 and this year I've started doing Masters. For this year I have to study LLVM because it can be part of my thesis

Hi, We are writing a binary translator with LLVM. There are a lot of duplicated load/store IR instruction generated by our binary translator. Is there any kind of optimization pass which can eliminate those duplicated load/store instruction? We know that this kind of optimization can be harmful under some circumstances such as multi-threading, but it's safe in our model. Bin LI,

Depending on the situation, you either want to use mem2reg or GVN.

Dear all: I installed the rsync 2.5.4 in my two machine (192.168.1.30 and 192.168.1.120, both are AIX OS) to backup data each other. The software`s installation is ok, and I can copy local files. But when I try to backup data between two machines, there reports some errors: >./bin/rsync -avz 192.168.1.30::web ./backup-3000/ rsync: failed to connect to 192.168.1.30: Connection refused

Dear all, Several days ago, I posted How to write a bmp file pixel by pixel. Instead of bmp, I succeeded in writing a PPM file by using the pixmap package. Thanks for the hint generously provided by Uwe Ligges. Now I have a new question. How to convert a PPM file to BMP file in R? I know I can do this in photoshop or by some other softwares, but I think if I Can do this in R, that

Hello dear R-users, I have a tricky problem of data manipulation with R. Although it seems very easy, I can not solve it by myselves. The problem is a variable in my dataset is usually be readed as "factor" (variable mode), however I want it be a "numeric" one. I want to know how can I define an variable/column in a dataframe as numeric mode, after I imported a large

Dear all, I open a bmp device by the bmp() function in the png package, but I don't know how to write color pixel by pixel into the file? Any help or hint? What I want to do is to create a 512*512 bmp file with certain dots being red and others black. I have all the pixel coordinates for the red dots, but I don't know how to draw the color on the device. Please help

Dear LLVMers, my name is Douglas, and I would like to participate in the Summer of Code this year. I am currently a Computer Science student at the Federal University of Minas Gerais, Brazil, and I work as a research assistant at the Programming Languages Lab, in that university. I work together with Andre Tavares and Andrei Rimsa, two summer of coders last year, and my advisor is Fernando
