[LLVMdev] Global constructors "get lost" when transforming bitcode files
...A strange problem appears when upgrading from release_34 to testing. Some transformations to bitcode files cause registered global_ctors to not be called. Here's an example (I've also attached the complete example and pasted it below): This works: clang -fsanitize=address -flto -c -o sum.o sum.c clang -fsanitize=address -o sum sum.o This doesn't work: clang -fsanitize=address -flto -c -o sum.o sum.c llvm-dis sum.o llvm-as sum.o.ll -o sum.o clang -fsanitize=address -o sum sum.o The second version segfaults when accessing shadow memory, because the memory...

Alternate ways of finding number of occurrence of an element in a vector.
Hi, I have a vector "v" and would like to find the number of occurrence of element "x" in the same. Is there a way other than, sum(as.integer(v==x)) or length(which(x==v)) to do the this. I have a huge file to process and do this. Both the above described methods are pretty slow while dealing with a large vector. Please have your comments. Praveen Surendran.

Bug or feature? sum(c(a, b, c)) != (a + b + c)
Greetings all, I'm porting an algorithm from MATLAB to R, and noticed some minor discrepancies in small decimal values using rowSums and colSums which are exacerbated after heavy iteration and log space transformation. This was rather perplexing as both programs claimed and appeared to use the IEEE 754 standard for floating point arithmetic (confirmed with manual basic operations). After some tracing and testing, I've...

Decimals in R/SQL
...in sqldf or RSQLite I lose the decimals in my matrix. The only way I can get decimals is by multiplying by 1.00000, etc. I have tried manipulating the options, but it is only effective once I multiply by 1.0000. I appreciate any suggestions! Thanks! Example: z <- sqldf ("select ST, SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from ss09 group by ST") z shouldn't be whole numbers. [[alternative HTML version deleted]]
