[LLVMdev] How can I obtain upper bound of a pointer?
This is rather off-topic for LLVM, it's a C programming question and the C answer is: you can't. C doesn't expose any way to find the upper limit of 'Ptr' you just have to keep track of what size you used yourself.

[LLVMdev] getMetadata(“dbg”) returns NULL
Hi, getMetadata(“dbg”) returns NULL for such a small program as follows: int main(){ char a[10], b[2]; if(a[0] != 0 && a[1] != 0){ strcpy(a, b); } return 0; } The compiling command is: llvm-gcc --emit-llvm -g -c ./src.c I also tried the solutions I found through Google: http://stackoverflow.com/questions/14943447/llvm-line-number-of-an-instruction

[LLVMdev] How to obtain CFG using llvm-gcc?
Hi, llvm-gcc is deprecated. It would be wise to avoid using it unless you have to! You don't say what form you want the control flow graphs in. AFAIK you can think of LLVM bitcode modules (emitted by using -emit-llvm flag) as a collection of global variables and functions. Each function is essentially a control flow graph. You can quickly take a look at a CFG by doing something like...

[LLVMdev] Google Summer of Code proposal: Adding memory safety checks to the LLVM bitcodes
Dear LLVMers, My name is Raphael Ernani, and I am doing my MsC at the Federal University of Minas Gerais, Brazil. I have been using LLVM for a while, and I would like to participate in this year's Summer of Code. One particular idea, in your "open projects" page caught my eye, and I decided to write a proposal about it. The line that I liked in the page was "Create an LLVM

[LLVMdev] SAFECode testsuite query
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

Intel MPX support (instrumentation pass similar to gcc's Pointer Checker)
Hello, As far as I know, there is no MPX pass in LLVM (though the x86-64 backend already declares MPX registers and instructions). I wonder if anyone is currently working on the LLVM pass for MPX instrumentation, similar to Pointer Checker in gcc. If yes, could anyone elaborate on the status and accessability to other researchers? And if any help is needed? Prof. Santosh Nagarakatte, the author

>Fromwhat you describe, your comp/limiter can't possibly be working correctly. It should be the last unit in line before the sound card, and needs to be adjusted properly. You also need to balance the levels on your mixing board (so that the correc t level comes at predictable place on the slider). It might be worthwhile to find someone with some sound-mixing or radio engineering experience

Hello, even though the study of Intel MPX took much longer than expected, we have finally finished it. Currently, it is published in two formats: * as a technical report: https://arxiv.org/abs/1702.00719 * and as a webpage: https://intel-mpx.github.io/ This work contains evaluation of MPX from perspectives of performance (Phoenix, PARSEC, and SPEC benchmark suites), security (RIPE and found

Lower bound and upper bound in maximum likelihood
Dear all, I need to simulate data which fit to a double poisson time series model with certain parameters. Then, check whether the estimated parameter close to the true parameter by using maximum likelihood estimation. Simulation: set.seed(10) library("rmutil") a0 = 1.5; a1 = 0.4; b1 = 0.3; g1= 0.7 ; n=100 #a0, a1 and b1 are parameter where n is size. nu = h =
