Hi, I found that some loops can not be identified by LoopInfo pass. For example, the loop at line 3094 of rdopt.c of benchmark 464.h264ref from spec cpu2006 is not a loop or a child (pr grandchild) of any loop in the loop list generated by LoopInfo pass. The documentation of LoopInfo says that it identifies natural loops, who have exactly one entry point. But the IR of this loops shows that it's header o...

I've just committed some fairly big changes to R-devel. - There's a new tag \Sexpr which allows R code to be embedded within the Rd file, similar to Sweave, \RdOpts corresponds to \SweaveOpts. - The parser now mainly issues warnings, rather than errors, in case of syntax errors. It throws away a few tokens and tries to restart. This should let you see most of your errors in one pass, rather than one at a time. (Don't ignore the warnings -- you...

...in the loop. There is probably some block outside of the loop jumping to a block in the loop body.

Dear testers, 5.0.0-rc3 was just tagged. This is a release candidate in the real sense: if nothing bad comes up in testing, this is what the release is going to look like. Please build, test and upload binaries to the sftp (use the /data/testers-uploads/ directory) and let me know what issues remain. I know we're a little bit behind schedule, but hopefully we can get to 'final'

Hi Stepan, Sorry for the delay. It's great that you are working on MergeFunctions as well and I agree, we should definitely try to combine our efforts to improve MergeFunctions. Just to give you some context, the pass (with the similar function merging patch) is already being used in a production setting. From my point of view, it would be better if we focus on improving its capability
