LLVM 3.8 change in function argument lists?
Hi,
I am upgrading my project from 3.7 to 3.8. I find that following code
used to compile in 3.7 but doesn't in 3.8 and I can't understand why.
llvm::Function *mainFunc = ...;
auto argiter = mainFunc->arg_begin();
llvm::Value *arg1 = argiter++;
arg1->setName("obj");
But if I change the code to following it compiles:
auto argiter = mainFunc->arg_begin();
llvm::Value

[LLVMdev] Is it valid to add parameters to a function once it is created
I create a function with an empty signature:
void llvm_start_new_function() {
llvm::outs() << "Staring new LLVM function ...\n";
Mod = new llvm::Module("module", llvm::getGlobalContext());
builder = new llvm::IRBuilder<>(llvm::getGlobalContext());
llvm::FunctionType *funcType =
llvm::FunctionType::get(builder->getVoidTy(), false);

[LLVMdev] Best strategy to add a parameter to a function
I am trying to build a function (C++ Builder) and at the same time
extend its parameter set. Here's what I try to do:
Value* arg0 = add_param_float("arg0");
Value* tmp = builder->CreateFAdd(arg0,some_previous_value);
Value* arg1 = add_param_float("arg1");
The function add_param_float should add a 'float' parameter to the
function and return its value. Right

[LLVMdev] noob IR builder question
I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely

Passing equations as arguments
Friends,
I'm trying to pass an equation as an argument to a function. The idea is as follows. Let us say i write an independent function
Ideal Situation:
ifunc <- function(x)
{
return((x*x)-2)
}
mainfunc <- function(a,b)
{
evala <- ifunc(a)
evalb <- ifunc(b)
if (evala>evalb){return(evala)}
else
return(evalb)
}
Now I want to try and write this entire program in a single

hurdle, simulated power
Hi all--
We are planning an intervention study for adolescent alcohol use, and I
am planning to use simulations based on a hurdle model (using the
hurdle() function in package pscl) for sample size estimation.
The simulation code and power code are below -- note that at the moment
the "power" code is just returning the coefficients, as something isn't
working quite right.

Method of L-BFGS-B of optim evaluate function outside of box constraints
Hi, R guys:
I'm using L-BFGS-B method of optim for minimization problem. My function
called besselI function which need non-negative parameter and the besselI
will overflow if the parameter is too large. So I set the constraint box
which is reasonable for my problem. But the point outside the box was
test, and I got error. My program and the error follows. This program
depends on CircStats

Problem with the LLVM v8.0 IR 'select' instruction
Hi again,
It is probably me doing something wrong, but I have attached a trimmed down
sample that shows the issue and the output that Clang 8.0.0 makes (using
the binary release from llvm.org).
I invoke clang as follows: clang -S -O3 -o Evergrowing.s -Wall
Evergrowing.ll
I tried using -O1, -O2, and -O3, but all where the same. Please notice
that I renamed 'main()' to

Creating a Polar Plot with expanding points as radius increases
I'd like to create a polar plot similar to those created by the polarFreq
function in the openair package. However, this package seems to be specific
to wind speed and direction, and requires a "ws" (wind speed) and a "wd"
(wind direction) column. My data is unrelated to wind speed, but I'd like
to be able to get a plot that does what polarFreq's plots do; I'd

deSolve: Problem solving ODE including modulo-operator
I have a problem integrating the 'standard map' (

By using the modulo-operator '%%' with 2*pi in the ODEs (standardmap1), the
resulting values of P and Theta, should not be greater than 2pi. Because
this was not the case, i was thinking that the function 'ode' has some

how to compute this summation...
Dear R users,
I try to compute this summation,

finding roots (Max Like Est)
I have this maximum liklihood estimate problem
i need to find the roots of the following:
[sum (from i=1 to n) ] ((2(x[i]-parameter)/(1+(x[i]-parameter)^2))=0
given to me is the x vector which has length 100
how would I find the roots using R?
I have 2 thoughts...... 1 is using a grid search ... eg. brute force, just
choosing a whole bunch of different values for my parameter .... such as

plotting circles
I'd like to make some polar plots with R, but I can't seem to find anything
designed to help with that. Is there anyway to get a real polar mode, where
instead of x and y you have r and theta? How about a way to draw a circle?

Adding sortables dynamically
Hi all,
is there a way to define the containment option for a sortable so
that it is a class name instead of an id list?
I have a case very similar to the sortable lists demo, the only
difference is that I'm adding new list containers dinamically, so
either I need to redo the Sortable.create calls for all new elements
to include the newly added container, or having someway to have them
