similar to: [LLVMdev] Behaviour of NVPTX intrinsic

I have written test.ll as below and ran 'opt' on it as " opt -std-compile-opts test.ll -S -o -" . But the output shows that there is code motion around the barrier intrinsics. test.ll ------- ; ModuleID = 'test.bc' define void @test(i16* %I_0, i16* %I_1, i16* %I_2, i16* %I_3, i16* %O_0) { entry: %T_0 = load volatile i16* %I_0 %T_1 = load volatile i16* %I_1 %T_2 =

I'm trying to use the rsync algorithm for incremental backups. After a quick look at rsync I saw the batch mode operations, and I thought that maybe I can modify them for incremental backups. What is needed is to add an option to save the checksums of all the files of the level 0 backup and a second option to use the level n checksum to calculate the delta batch files for the level n+1

I'm working on a personal project which involves lowering a superset of LLVM to "vanilla" LLVM. Part of this involves rewriting types. I'm working off of the 2.6 code base, so this may have been addressed in a bug fix. I'm having trouble with refineAbstractType and recursive types. Specifically, I'm creating opaque types to serve as placeholders for the final

Hello, can anybody here explain what a Jonckheere-Terpstra test is and whether it is implemented in R? I just know it's a non-parametric test, otherwise I've no clue about it ;-( . Are there alternatives to this test? thanks for help, Arne

Hi,   I have a system in which I analyze 2 subjects and 1 variable, so I have 2 models as follow:   y ~ x_1[, 1] + x_2[, 1] + x_1[, 2] + x_2[, 2]   Where   x_1[, i] = cos(2 * pi * t / T_i) x_2[, i] = sin(2 * pi * t / T_i)   i = 1, 2   Data have two columns: t and y.   As you can see, I have a multiple components model, with rithm and without trends, and I have a fundamental

The actual purpose that I wanted such an intrinsic is to solve a problem similar to this one in X86. Say I wanted to read the "mxcsr" register(which is the status register for SSE instructions) after a particular instruction, then I need a kind of barrier intrinsic which will not allow the arithmetic instructions to move around it. Or else I will be reading the status of some other

Hi, I am using attr_accessor attributes in model class and assigning the values to attr_accessor dynamically in controller. And am sending the data object to display in Yaml format. I am getting the response along with changed_attributes but I don''t want changed_attributes details in my response. build Model code class Test < ActiveRecord::Base attr_accessor: t_1, t_2, t_3, t_4 end

Hi, I have a function that I need to do double integration: \int^T_0 \int^t_0 N(\delta / \sigma \sqrt(u)) (1-N(\delta / \sigma \sqrt(u))) du dt where N(x) is a standard normal probability of x. I start off by writing an inner integral into a function. Meaning \int^t_0 N(\delta,\sigma \sqrt(u)) (1-N(\delta,\sigma \sqrt(u))) du. Then calling integrate function on this function. This

I have defined the intrinsic as * def int_loop: Intrinsic<[],[llvm_i8_ty, llvm_empty_ty],[]>;* and also got the Codegen backend support in Instructioninfo.td file. Then created a .ll file to test it. The .ll file is like this *declare void @llvm.loop(i8, label)define void @fn() nounwind readnone {entry: ..... ..... call void @llvm.loop(i8 10, label %entry) ret void}* But

Hello everyone, Consider we have this following set of code: int foo() { int a,b; a = __builtin_XX(0x11); b = __builtin_XX(0x11); return a+b; } The problem currently is that LLVM eliminated the second call and copied the result from the first call into a new set of registers. Is there is a way to force LLVM to generate two explicit calls to a builtin function. The builtin takes in an integer

Hi, I noted a discrepancy between R and openepi when I ran a fisher test with the same matrix. In R: > a=matrix(c(1,2,6,17), nrow=2) > a [,1] [,2] [1,] 1 6 [2,] 2 17 > fisher.test(a, conf.int=T) Fisher's Exact Test for Count Data data: a p-value = 1 alternative hypothesis: true odds ratio is not equal to 1 95 percent confidence interval: 0.02061498

Dear Colleagues, I have a data set that looks as below. I'd like to count the number of dates in a series of arbitrary ranges (breaks) i.e. not pre-defined breaks such as months, quarters or years. table(format()) produces ideally formatted output, but table() does not appear to accept arbitrary ranges. I also tried converting the dates to numeric and using histogram to try to get the data,

Have a look at how the ARM backend handles the CPSR register. It sounds like what you're really looking for is liveness of that status register not to be clobbered between the arithmetic instruction you're inspecting and the instruction that reads that register.

Hi all, I am using GAM to model time trends in a logistic regression. Yet I would like to extract the the fitted spline from it to add it to another model, that cannot be fitted in GAM or GAMM. Thus I have 2 questions: 1) How can I fit a smoother over time so that I force one knot to be at a particular location while letting the model to find the other knots? 2) how can I extract the matrix

Dear All, I have already posted before on the list about data mining and it has proved very useful. I have now a training dataset consisting of N objects of M<<N different kinds (actually, M is usually 3 to 5, whereas N is of the order of 1000). Every object has its own label L_i, i=1...N, that is known. For each of these objects I measure some property in time (let's say I measure it

> The harm comes if the intrinsic ends up with the wrong value, or attached to the wrong loop. The intrinsic is marked as IntrNoDuplicate, so I wasn't worried about it ending up somewhere else. Also, it is a property of a specific loop, a tail-folded vector loop, that holds even after it is transformed I think. I.e. unrolling a vector loop is probably not what you want, but even if you do

Dear List: I'm trying to use the boot function to estimate some standard errors. I actually programmed a bootstrap using some homebrew code and it worked fine. But, I am trying to use the more efficient boot function. I have placed some sample data for replication of my problem at the bottom of this email. For the sample problem, I have 10 subjects each with 5 observations Y_t = (t_1, ...,

Let me first tell you that you and your cohorts are doing a great service to the statistical community with R. I have been working with Rseptbeta under Win95 and I am very impressed with its capabilities. I thought I give you some feedback gained from my limited playing with R.

Hi, Arm have recently announced the v8.1-M architecture specification for our next generation microcontrollers. The architecture includes vector extensions (MVE) and support for low-overhead branches (LoB), which can be thought of a style of hardware loop. Hardware loops aren't new to LLVM, other backends (at least Hexagon and PPC that I know of) also include support. These implementations
