Complex summary of counts of rank positions over multiple dataframes
...rank etc.
A resulting dataframe could look like:
uniquevars <- c("A","B","C","D","G","J","K")
rank1a <- c(2,1,0,0,0,0,0)
rank2a <- c(1,2,0,0,0,0,0)
rank3a <- c(0,0,1,1,1,0,0)
rank4a <- c(0,0,1,1,0,0,1)
result_a <- data.frame(uniquevars,rank1a,rank2a,rank3a,rank4a)
In addition I would like to have for all populated 'cells' of the
result_a-dataframe the sum of the all 'values' from the original dataframes
instead of the counts.
Like:
rank1b <- c(34,24,0,0,0,0,0)
rank2b <- c(6,...

Hi!

int main()
{
float a = 0.3;
double b = 0.3;
float result_a = std::tan( a );
float result_b = std::tan( b );
std::cout << "tan float: " << result_a << std::endl;
std::cout << "tan double: " << result_b << std::endl;

...5. opt + llc + as + llvm-g++
Output:
tan float: 0
tan double: 0
????
In summary: Everything works except linking with llvm-g++!

It fails on x86 using x87 floating point, with the inliner not run,
because of 1505, yes. Gonsolo, is that your situation?
(What happens is, there is a wrapper in the header file for std::tan
(float),
