Hi, Looking into LLVM for a database query engine project... After downloading the latest source from CVS, it's my first time trying to build LLVM. Following the "Getting Started" instructions, all went well until gmake reported this error while trying to link llc: In function `(anonymous namespace)::BreakCriticalEdges::getAnalysisUsage(llvm::AnalysisUsage&) const':

The following is a re-post (after suggestion from martin) of a mail I sent to r-core this morning, maybe some of you are interested: >>>>> On Tue, 11 Nov 1997 08:34:16 +0100, >>>>> Kurt Hornik (KH) wrote: KH> As Andreas & Fritz & I have recently, in attempts to port various pkgs KH> to R, come across the f2c problem again, I thought I'd ask ...

Version 0.60 of R for Unix is now available. Release of this version has been delayed for a variety of reasons, but we hope that it will provide a good deal more stability and functionality than previous versions. However it should be regarded as of "alpha" quality for a short shakedown period. We would like user feedback to help us improve the quality of R. You can do this by

Hi all. I've been lurking and posting on this list for a few years now. Prior to that, I managed the US Convertible Arbitrage portfolio for Amaranth Advisors. I recently agreed to manage a similar portfolio for a different hedge fund and am looking for someone to join me, essentially as the principal quant for a new San Francisco office. I've been very impressed with the posters on

Also in assign() there some arguments lacking in R such as 'frame' and 'where', though I guess that 'frame' in S may be similar to 'pos' in R.

Hi, I have the following C loop to vectorize: struct box { double* source; }; void test(double* restrict result, struct box my_struct, int len) { for (int i=0 ; i<len; i++) { result[i] = my_struct.source[i] * my_struct.source[i]; } } There are two references in the loop, result[i] (restrict) and my_struct.source[i] (readonly). The compiler should easily figure out that

Hello all: Why arbitrage rarely works. Peter Dalgaard's "Introductory Statistics with R" sells on AMAZON U.S. website at USD 44.95 and on AMAZON U.K at GBP 21.00. At the current exchange rate, the U.K. price translates to USD 32.68, a 27% savings BUT for delivery: the U.S. AMAZON promises 6-10 days whereas in the U.K. 4-6 weeks is promised.

Calls of the form data(package = pkg) inside a function incorrectly fail ("pkg" is a local variable). For instance, foo <- function(pkg) data(package = pkg) foo("base") Error in .find.package(package, lib.loc, verbose = verbose) : none of the packages were found ## workaround -- force argument "package" to be an expression ## (not a

I do not have access to the bug reporting system. If somebody can get me access, I can create a formal bug report. The latter issues seem like duplicates of: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=12572 (with slightly different output), but as that bug was reported nearly 10 years ago, it might be worth creating an update under R version 3. I could not find the first issue when

Hi All, I am using llvm-3.0 release version for compiling some files. I have a cpp file on which I did a few custom passes. After that I used llc to convert the *.bc file to *.s file at -O1 optimization level. llc took ~2630 seconds to perform this conversion. I timed llc and these are the top three passes that is taking most of the time. ---User Time--- --System Time-- --User+System--
