Hi I use BlockAddress to get the address of BasicBlock , and I use GlobalVariable 's getInitializer() to pass the address of BasicBlock to the global variable of my own program and then I print it out. But , I found that BlockAddress is not always correct. For example, some function's rsp (stack pointer) or other register is maintained by caller, so it would be like:

...------------------------------------ setClass('foo', representation=representation(stuff='list', bar='numeric'), prototype=list(stuff=list(), bar=0), contains='.environment') setGeneric('doit', function(.Object, newfoo='environment') standardGeneric('doit')) setMethod('doit', 'foo', function(.Object, newfoo){newfoo@bar <- 10}) z <- new('foo') z@stuff$x <- new('foo') doit(z,z@stuff$x) z@stuff$x@bar [1] 0 -----------------------------------...

Hi, Suppose I have created something like this in R: foo <- "myfoo" and I want to find out the number of character in foo (in other words, R should return 5 since "myfoo" has 5 charactors. How can I do it? I tried: length(foo) but it returned 1. Cheers, Kevin ------------------------------------------------------------------------------ Ko-Kang Kevin Wang

I have very large csv files (up to 1GB each of ASCII text). I'd like to be able to read them directly in to R. The problem I am having is with the variable length of the data in each record. Here's a (simplified) example: $ cat foo.csv Name,Start Month,Data Foo,10,-0.5615,2.3065,0.1589,-0.3649,1.5955

Hi, I think this is a very ashamed question I have modified the version of the MSP430, after many problems it compiled, now I want to see is the changes generate what I want, but I don't know how for example with llc -march msp430 foo.ll -o newfoo.ll generates a file for the msp430 and actually did it. but I want to load my changes the --load option is supposed to do that, but the only new files that the compiling process did are: llvm-2.8/Release/lib/libLLVMMSP430Info.a llvm-2.8/Release/lib/libLLVMMSP430AsmPrinter.a llvm-2.8/Release/lib/l...

Hi Roberto, The PIC24 family of devices share very little commonality with PIC16 beyond the naming convention. They're a register-based 16-bit architecture, unlike the PIC16. That said, that does mean that LLVM is a much more reasonable fit to target the PIC24 (and dsPIC) than it is for PIC16. Modeling your target files after the MSP430 or Blackfin backend is likely your best bet to get up

I have been analyzing the implementation for some backend (PIC16, MIPS, SPARC and MSP430) my main problem is that they are so much different, I mean obviously they are describing different architectures, but the file structure is not the same. So it is difficult to get a pattern. I have checked the available documentation files, also the video from Cardoso about how to write a backend for the
