the name of the observation. (I am dealing with repeated measurements
for the same observation)
So when I open the dataframe in R it looks like this
Col1 Col2 Col3
name1 val1 val2
val3 val4
....
name2 val5 val6
val7 val8
Everything is fine, except that the name of the observation is on the

[LLVMdev] algebraic (de)optimizations form long chains of dependent operations
Hi,
when I compile (clang -O3) and optimize (opt -O3) C-code like this:
sum1 = val1 + val2;
sum2 = val3 + val4;
sum3 = val5 + val6;
sum4 = val7 + val8;
sum5 = sum1 + sum2;
sum6 = sum3 + sum4;
sum7 = sum5 + sum6;
sum += sum7;
I get bitcode like this:
if.end152: ; preds = %if.then150, %if.else146, %if.end137
%val8.0 = phi i32 [ -2048, %if.then150 ], [ %conv38, %if.else146 ]...
