Yes.  I

Hi all, I think I've spotted a semantic issue with marking @malloc and @realloc as noalias.  Say we have the program: int f() {   int* p0 = malloc(size of(int));   free(p0);   int* p1 = malloc(sizeof(int));   if (!p1) return 20;   int value = 0;   for (int i = 0; i < 1; i++) {     *p1 = 20;     value = *p1;     if (false)  // "false" is obscured in a way the compiler can't

Talking to Nick Lewycky on IRC, I figured out a shorter way of saying what I wanted to say.  We know that programs like this

Dear R users, I am trying to carry out MLE of the time-varying CAPM using the FKF package. My approach so far has been to try and adapt the example given in the help file found using ?fkf which demonstrates the MLE of an ARMA(2,1) model. When I attempt to run my R code (given below) I get the following error: Error in fkf(a0 = sp$a0, P0 = sp$P0, dt = sp$dt, ct = sp$ct, Tt = sp$Tt, : Some of

(I try to answer on multiple mails in one) First of all, it seems like some generic notes should be given here: 1. Generic MIPS "SYNC" (aka "SYNC 0") instruction is a very heavy in some CPUs. On that CPUs it basically kills pipelines in each CPU, can do a special memory/IO bus transaction (similar to "fence") and hold a system until all R/W is completed. It is

The corresponding line does not exist, and it is in fact, wrong :) C11 says nothing like that. C++14 says: "The lifetime of an object of type T begins when: — storage with the proper alignment and size for type T is obtained, and — if the object has non-trivial initialization, its initialization is complete. The lifetime of an object of type T ends when: — if T is a class type with a

I am trying to locate a bug that affects my Blackfin backend. I am having some trouble understanding the semantics of def/kill flags on machine operands when using subregisters. I compile this function: define void @i56_ls(i56 %x) nounwind { store i56 %x, i56* @i56_s ret void } And get this initial machine code: Live Ins: %R0 %R1 %reg1025D<def> = MOVE %R1 %reg1024D<def> =

Hi, Could any one please tell me if there is any way to remove 11 letters long cryptic output from -ii option.

sapply() stems from S / S+ times and hence has a long tradition. In spite of that I think that it should be enhanced... As the subject mentions, sapply() produces a matrix in cases where the list components of the lapply(.) results are of the same length (and ...). However, it unfortunately "stops there". E.g., if you *nest* two sapply() calls where the inner one produces a matrix, very

In a lattice 11x11 with 6 repetitions, we want to compare lines to their two parents. 3 of the 6 repetitions are sprinkled and the 3 others not. There are 5 factors : hm (hydrous mode), variety, block, rep and grandrep. grandrep gathers two repetition, a sprinkled and a not (as in Split Plot !). I use lme but I have problems in random. Can someone help me ? Ibnou DIENG

Did anything change that could have caused this problem? Unfortunately simply going back in rails alone to the original "RC2" git-tag did not immediately help, so it may be some other problem (on my own system only, even if I''m
