Hi Max, > The Glasgow Haskell Compiler LLVM backend is generating a lot of code which > appears to be optimised by LLVM quite poorly.

I am seeing the wf loop get optimized just fine with llvm 2.8 (and almost as good with head). I'm running on Mac OS X 10.6. I have an apple supplied llvm-gcc and a self compiled llvm 2.8. When I run $ llvm-gcc -emit-llvm -S M.c $ opt -O2 M.s | llvm-dis I see that: 1. Tail recursion has been eliminated from wf 2. The accesses to sp have been promoted to registers 3. The loop has

It is the scalar replacement of aggregates pass that puts everything into registers when sp is a local array. What happens is: the tail recursion in wf is eliminated. wf is inlined into g. scalarrepl turns the

I rechecked this and am I actually seeing the same results as you. I think I must have made a stupid mistake in my tests before - sorry for the noise. However, I found that we have a phase ordering problem which is preventing us getting as much

Can someone tell me why this is since I can't seem to find an explination in the docs or FAQ for this. Since there are no "BM" in the mtrs data.frame, but only in the "parent" data.frame (trees), I'm assuming the subset data.frame is still associated with the original. Is that correct and how would I create a completly separate data.frame since I'll be using by,

Hi, I have a dataframe wf existing of a header with different labels and beneath the values of those labels : wf: label1 label2 ... 0,45 0,21 0,10 0,45 .... .... I have a list fl <- c("label2","label3",..) Isn't possible to use the list elements in the list in order to subtract values from the dataframe? like : wf$fl[[1]] When I do in R I get :NULL

Hi David, I got a problem related to the change made in r188651 - not including file/line info for artificial arguments like "this" and "self". Would you be able to take a look at it, please? I am compiling the code for ARM linux with fast ISel disabled: -mllvm -fast-isel=0. The problem is that it's not possible to step intothe constructor, destructor or a method of a

Hello, I am trying to create a plot often seen in hydrodynamic work than includes a contour plot representing the water speed with arrows pointing in the direction of flow. Does anyone have any idea how I might add arrows based on wf$angle (in the example below) to the plot below? Thanks in advance! Sam library(lattice) speed <- runif(100, 0, 20) wf <- data.frame(speed) wf$width <-

R gurus: I'm trying to get another round of rconifers out and I need some advice/help crushing differences in the examples test. I'm trying to make sure the max sdi values are being respected. I've added a tests/rconifers-Ex.Rout.save (from windows i386-pc-mingw32) and when I ran R CMD check (both R-2.13.0), I got the following results: * using log directory

Hi, I keep getting the below error regarding rJava which is required by package xlsx (I have used it in the past to directly import data from Excel 2010). I was on R version 2.15.0 when I was getting this error this morning. So I upgraded to 2.15.1 but still the same problem. I tried unstalling and reinstalling xlsx and even rJava directly from the source as indicated here:

Hi all, I am a new graduate student who is also new to R. I am ok with the basics, but the problem I am having right now seems beyond what I can do..so I am looking for advice. I am trying to pull data from flat ASCII files, but they do not have a "nice" structure so a simple "read.table" doesn't work. An example first half of a data file is below:

Summary ======= There is a need for dedicated continuation-passing style (CPS) calls in LLVM to support functional languages. Herein I describe the problem and propose a solution. Feedback and/or tips are greatly appreciated, as our goal is to implement these changes so they can be merged into LLVM trunk. Problem ======= Implementations of functional languages like Haskell and ML (e.g., GHC

I'm solving the following problem: Create a variable (column) in the ?wf? dataframe named ?Zone? that takes value of ?tropic? if Latitude is less than or equal to 30, or ?non-tropic? for Latitude greater than 30. Show you Zone variable. Latitude is a column of my dataframe. I don't know the sintaxis and the process to create the column. [[alternative HTML version deleted]]

Hi All, I found some cases where a spill of a live range in a block is reloaded only in one of its successors, and there is no reload in other paths through other successors. Since the spill is reloaded only in a certain path, it must be okay to sink such spill close to its reloads. In the AArch64 code below, there is a spill(x2) in the entry, but this value is reloaded only in %bb.1, not in
