Hello all, Recently I started playing with running R scripts on the Condor system in my institute. (For more on this, have a look at: Running Long R Jobs with Condor DAG by Xianhong Xie link: http://cran.r-project.org/doc/Rnews/Rnews_2005-2.pdf ) Might someone advice me about the following question: How should I handle the RNG (random number generation) in the running of parallel instances of R

Linux kernel is using the “asm goto” feature, other projects probably use it as well. I think it provides motivation to support it in LLVM. Regarding the complexity, I believe there is some infrastructure that we can at least partially reuse (the support for “indirectbr” instruction). My focus is adding “asm goto” support, the other things are indeed completely orthogonal and came up in bugs
