I'm sure there is a solution to this. Lets find it. Erik -- ----------------------------...

...ctorization. Do we need to pass any > additional flags to actually achieve autovectorization via llvm Currently, we only have basic-block vectorization, so to get autovectorization of loops (which is probably what we want here), the loops need to be unrolled. I see that all categories include -funroll-loops, does that do anything if we're not using gcc's optimizations? I generally run with both -unroll-allow-partial and -unroll-runtime so that llvm's unroller will do as much as it can. Also, in many of these cases, it looks like the vectorization is doing *something*, just not anyt...

...Chapter 7. Optimizing your applications) the path of moving from -O2 to higher degrees of optimization is discussed. On pages 48 and 49 it discusses -O3, -O4 and -O5 - and the bottom of page 49 discusses only adding the a variation of the options -qhot to act on loop transformations. In summary, -funroll-loops is not a vac/xlc flag I am aware of - but there is documentation to be had to help setup your own customization. imho, anything beyond -O2 needs careful. At least for xlc/vac, unless you specify -qstrict with -O3 and above you are permitting the compiler to reorder code (blocks). -- You ar...

Jan Stary wrote: > Yes, that's for DEBUG. > But why does it strip -O2 and add -O3 with NDEBUG? Well thats something from before I took over as FLAC maintainer. My understanding is that '-O3 -funroll-loops' gives the next encoder and/or decoder performance.
