...o also have covered efforts to make better use of unreachable for optimization purposes: http://llvm.org/bugs/show_bug.cgi?id=810 I've added a comment and assigned it to you as requested.

Hi, is there any way to execute scripts in R (Windows) without the script being copied to the console, so that only error messages are reported? Or to have a second console in parallel? Please. Not being able to hit the F10 button like in S-Plus seriously impairs my productivity (not only because it is slow and clutters my console history). And totally unrelated: Is there any chance that R

Hi, When clang/llvm compiles the following sample (with -O2) it optimizes away the second comparison in test1 but not in test2. Is this handling of 'unreachable' by purpose, or is this just a shortcoming of the current optimization passes? GCC and MSVC (with the equivalent code using the __assume intrinsic) both optimize away the comparison in test2. void f1(); void f2(); void

Hi, Currently the hashing implementation in ADT/Hashing.h produces hash values on 32-bit platforms that differ from the lower 32-bits of the hash values produced on 64-bit platforms. It seems the only reason for this difference is that the uint64_t integer seed is truncated to size_t. Since the usage of uint64_t and size_t as types for seed values in the implementation is somewhat

Hi, I need to estimate the density at the mean of a sample of a few thousands data points with a dimesion up to 5. The data is uni-modal and regularly shaped. I couldn't find any kernel density package for R which supports more than 3 dimensions. Have I overlooked a package or does somebody have code for this purpose? Any other advice? Regards, Stephan

Hi How do I set the language of the GUI? With R 2.1.0 it suddenly changed to German and I want it to stay English. I couldn't find any setting to change. Regards, Stephan

I spent a week to optimize LLD performance and just wanted to share things what I found. Also if there's anyone who have a good idea on how to make it faster, I'd like to hear. My focus is mainly on Windows, but my optimizations are generally platform neutral. I aim both single-thread and multi-thread performance. r231434 <http://reviews.llvm.org/rL231454> is a change that has the
