Hi, On ARMv6T2 this turns cttz into rbit, clz instead of the 4 instruction sequence it is now. I'm not sure if adding RBIT to ARMISD and doing this optimization in the legalize pass is the best option, but the only better way I could think of doing it was to add a bitreverse intrinsic to llvm ir, which itself might not be the best option since bitreverse probably isn't too common.

I wasn't hoping to be able to pattern-match something so complicated.

I thought I was clever. I produce both ps and pdf files from LaTeX (MiKTeX), so sometimes I need to get .eps graphs from R, sometmes .pdf. To rationalize this I wrote the following function to let me easily choos what I want wihtou changing the code in my R-programs too much (here embedded in a small test program): plt <- function( file, type = "pdf", dir =

When I execute the following code: bitmap("test.pdf",type="pdfwrite") plot(1:10,1:10,main="ONE") plot(1:10,1:10,main="TWO") dev.off() the resulting file test.pdf contains four pages: graph ONE, graph TWO, graph ONE, graph TWO. I can recreate the problem with R version 1.2.1 and 1.2.2. I am using Aladdin ghostscript version 6.50. The temporary file

Michael Lapsley was suggesting on R-help direct copies to gif/png/jpeg. The following seems to do a sensible job for me of copying the current device to any bitmap format supported by gs. The manipulation is needed to work around assumptions made by postscript(), and I think better fixed in postscript() (but not a couple of days before a release). I want to make onefile=FALSE work on

Hi all, I''m trying to integrate Capistrano (thanks Jamis and DHH for such a lovely piece of software) into an application I''m writing. I can''t figure out, though, how to get output from capistrano when it''s used through the CLI or configuration class, however. I see that it implements a logger (Logger) and I see that starting on line 12 of the included
