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 r-users, I would like to solve system of nonlinear equation using BBsolve function and below is my code.  I have 4 parameters and I have 4 eqns. mgf_gammasum <- function(p) { t  <- rep(NA, length(p)) mn <- 142.36 vr <- 9335.69 sk <- 0.8139635 kur <- 3.252591 rh  <- 0.896 # cumulants k1 <- p[1]*(p[2]+p[3]) k2 <- p[1]*(2*p[2]*p[3]*p[4] +p[2]^2+p[3]^2) k3 <-

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

I used the command below, but R gives me the error message--syntax error. can anyone see the mistakes I made? optimize(function(x,y) + ((327.727-(1-0.114^10)*y*(1-x)/x/(1-x^y))+(9517.336-327.727 *(1+(1-x)*(1+y)/x-327.727)))^2 + interval=c(0,1)) At the same time, I use nlm() but R gives me the code $code [1] 3 function(vals) { x <- vals[1] y <- vals[2]

Hi, I have a vector called nfichiers of 138 names of file whose extension is .P0 or P1 ... to P8. The script is not the same when the extension is P0 or P(1 to 8). Examples of file names : [128] "Output0.P0" [129] "Output0.P1" [130] "Output0.P2" [131] "Output01102007.P0" [132] "Output01102007.P1" [133]

No, since I'd like to test null: p <= p0 alternative: p > p0. and my understanding is that binom.test tests null: p = p0 (can only be a "simple" null hypothesis according to help(binom.test)) alternative: p > p0 (or p < p0 or p != p0).

Went to use ActiveSupport in a gem today and got an error on account of not having i18n installed. Either bundler should be installing i18n along with activesupport or docs need to be updated. quick repro: https://github.com/softwaregravy/repro_active_support_i18n bundle exec irb require ''active_support/all'' detailed steps and error: 1) add to Gemfile require

Hi I am been trying in vain to auto-gen models by reverse-engineering mysql using RMRE. It complains mysql2 gem missing but as seen in my Rails environment below, it is there. Here''s my Rails environment and RMRE error. Experts... please help! Thanks a ton in advance!! === Ruby version 1.9.2 (x86_64-linux) RubyGems version 1.3.7 Rack version 1.2 Rails version 3.0.3 Active Record

Hi all, I tried testing with Rspec for first time, following a tutorial. "rspec spec/" works fine but when I try ''autotest'' it gives me the error message below. I also made a gist about it: https://gist.github.com/779265 It seems like a redgreen or ZenTest error. I''m using Ubuntu10, Rails3, Ruby 1.9 and RVM. Any help is appriciated, thanks in advance, gezope

Dear Spencer and Prof. Fox, Thank you for your replies. I'll very appreciate, if you have any ideas concerning the problem described below. First, I'd like to describe the model in brief. In general I consider a model with three equations. First one is for annual GRP growth - in general it looks like: 1) GRP growth per capita = G(investment, migration, initial GRP per

Hi all,I'm working on my own backend for a custom CPU. I have defined paired registers for 64bit operations, however to set a 64bit paired register with 64bit immediate I have to set each register in that pair separately with the higher and the lower 32bits of the immediate. Could anyone give me an advice how to describe it in *InstructionInfo.td or point me to something similar in the LLVM

Yes.  I

Hi all, I have some problems with my gvinum setup after the system panic'ed. Afterwards the system fails finding the plexes to the subdisks (or at least that is what I can understand after having searched the gvinum source code for the error string in the DMESG log..) The machine is an IBM Netfinity 5000 and the internal HW self tests does not find any errors in the hw. Luckily my root is

I have one equation, two unknowns, so I am trying to build the solution set by running through possible values for one unknown, and then using uniroot to solve for the accompanying second solution, then graphing the two vectors. p0 = .36 f = function(x) 0.29 * exp(5.66*(x - p0)) f.integral = integrate(f, p0, 1) p1 = p0 + .01 i = 1 n = (1 - p0)/.01 p1.vector = rep(0,n) p2.vector = rep(0,n) for (i

Hi, I found the following strange effect with qbinom & partial argument matching p0 <- pbinom(0, size = 3, prob = 0.25) qbinom(p0, size = 3, prob = 0.25) ## 0 o.k. qbinom(p0-0.05, size = 3, prob = 0.25) ## 0 o.k. ## positional matching: qbinom(p0, 3, 0.25) ## 0 o.k. ## partial argument matching: qbinom(p0 , s = 3, p = 0.25) ## 1 ??? qbinom(p0-0.05,

Hello everyone, Let me (re)present a question that might have previously been discussed, but did not result in any code (AFIK). How do we represent a _conditional_ assignment (def) in a bundle MI? More contents - currently we expose internal def/use/kill information to a bundle header - something like this: BUNDLE %PC<imp-def>, %R0<imp-def>, %P0<imp-use,kill>,
