similar to: [LLVMdev] Interprocedural Program Slicing

We have done a few class projects on static interprocedural slicing but they are all of "course project" quality. I will put you in touch with some of the students who did those, if you're interested? --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Aug 15, 2008, at 8:48 AM, Silviu-Ionut Ganceanu wrote:

Hi, I need to modify the stemming for a couple of words (a blacklist) and for all the other to use the usual snowball stemmer. The "natural" way of doing it would be to derive from Stem and override operator ()... but I am using *python-bindings*. Would this be possible? If not I have two other solutions in mind: - add a custom stemmer to Xapian - write custom index & search

I have a problem where I add an Andersens AA pass to the pass manager, but it appears to get invalidated by another pass, and never rerun. My understanding from reading the documentation is that when a pass gets invalidated, it should be rerun before any other passes that requires it. Here is a simple example of the problem I am seeing: PassManager passManager; passManager.add(new

I added "plogis" to the derivative table in the development version of R; the patch against yesterday's R-devel src/deriv/main.c is available at http://www.zoology.ufl.edu/bolker/deriv_patch.txt . I pretty much followed the framework of the other symbols; here was my incantation - } else if (CAR(expr) == PlogisSymbol) { - ans = simplify(TimesSymbol, -

I admit it, when it comes to rSpec, I''m lazy. I''ve made a few feeble attempts to use it, but for once I''m waiting for a book-length treatment. At least two books were announced, I think. Can anyone in the know please report on their progress? Thanks Michael -- Michael Schuerig mailto:michael at schuerig.de http://www.schuerig.de/michael/

Crossbow team, The following is of interest to the Crossbow project. Since a large chunk of these changes also exist in the Crossbow gate, the delivery of this wad will result in fewer lines of changes for Crossbow''s delivery. If someone on Crossbow could participate in this review, that would be a bonus (Eric Cheng made original changes in the Crossbow gate at some point last year).

I''m trying to finish up a comp lab sign-in app in RoR that includes a db table logging each visit with a timestamp. I want to be able to loop through the visits table and get a weekly or monthly array and print a table of the last four weeks listing a count for the number of visits each day. I''ve got it working alright but it''s pretty ugly...overcoded. Does anyone

Hello, I have used SAS for multi-factor ANOVA, and found the SLICE function of LSMEANS to be valuable. Is there an equivalent function in R, and if so, where might I find it? Thanks in advance for suggestions, and thanks for access to this invaluable knowledge base. Corey [[alternative HTML version deleted]]

I'm designing a language that supports array slicing. Does LLVM allows conversions between array pointers? For example, can I cast a pointer-to-array-of-5-ints to a pointer-to-array-of-3-ints? Can I get the address of the third element of an array-of-5-ints and convert it to a pointer-to-array-of-3-ints? Then again, I suppose a pointer-to-int would work just as well since LLVM

Hi all... I am developing a program slicing framework using LLVM. The idea is to remove the computation parts from the program and only keep the parts relevant for the control flow. For example, in the following C loop. for (i=0;i<=VAL;) { printf("In the loop"); a=b+c; b=h+k; i++; printf("%d",i); } after slicing... for (i=0;i<=VAL;) { i++;

Hi All, Are there any known implementations of static inter-procedural slicing for LLVM (especially forward slicing)? I did find a few references to it in the archives dating back to 2008, but am not sure what the current status is. Any pointers would be highly appreciated.

A list contains several matrices. Over all matrices (list elements) I'd like to access one matrix cell: m <- matrix(1:9, nrow=3, dimnames=list(LETTERS[1:3], letters[1:3])) l <- list(m1=m, m2=m*2, m3=m*3) l[[3]] # works l[[3]][1:2, ] # works l[[1:3]][1, 1] # does not work How can I slice all C-c combinations in the list?

Dear Jin, I've talked with Vikram, and we agree that having this code (and a dynamic backwards slicing pass that Swarup and I wrote) in a publicly available SVN repository is a good thing. I'll try to get you a copy of the static slicing code some time next week (I should be able to work on it Monday morning) so that you can start working with it right away. I can work on making a

Hi all, I've been trying to work out how to slice an array of arbitrary dimension. I found a message showing how to stick two arrays together, but so far have been unable to transform that into what I need. Assume that I have a four dimensional array for example: array4d , , 1, 1 [,1] [,2] [1,] 3 6 [2,] 1 1 , , 2, 1 [,1] [,2] [1,] 4 7 [2,] 8 7 , , 1, 2

Hello John et al - I have been struggling to implement static backwards slicing with LLVM. After digging llvmdev postings for some time, I see that other people were having similar difficulties and John's got almost complete code that may be shared. May I get a copy of it, too? Better yet, it would be helpful for many other people if the code were checked in to an example directory or

Dear list. It is a known issue that accessing slots of S4 objects and in particular accessing .Data slots is slow in R. However, what surprises me are two things demonstrated in the code below (runnable with 'inline', my times are in the comments): - copying data out of a large 3x1e7 .Data slot into a matrix can be easily made 3-4 times faster than accessing a .Data slot which I believe

John, Thanks for your quick reply. Firstly, I'd like to employ a slicer for our benchmarking work (in one word, reducing the long-time irrelevant computing). I find the giri project and the LLVMSlicer[1]. However, the giri doesn't seem a complete implementation to me. I admit that I have not finished reading document/discussion, e.g. the previous threads in this mailing list. While the
