Handle loading of bool* correctly

1

Currently, it's not possible to load from a bool pointer. E.g. ```cpp xt::uvector xbools(100, true); xsimd::load_unaligned(&xbools[0]) ``` fails with substitution errors. Now it's actually a question *what* we should do...

There are some small failures with loading 64bit integers from char for `-arch=nocona` ``` [ RUN ] xsimd.api_load 1: lhs = 67305985 - rhs = 1 2: lhs = 134678021...

`cvttps` uses truncation and `3/5 == 0` becomes true which seems to be the default behavior in C++

Add arange

1

SIMDified arange can give a ~4x improvement about `std::iota` and for loops.

Implement transpose

2

We should implement a transpose operation to transpose NxN matrix blocks (where N is batch width). The interface should probably look like the one for haddp, e.g. taking a pointer...

We have a prototype for a cumulative sum using xsimd here: https://gist.github.com/jpivarski/b2a04778124e7dc790d87fcdfd399e1e/ We should work to integrate it into the library.

Dynamic progress bar only prints when accessing progress bar

3

The current implementation only prints when indexing into the progress bar and doesn't expose the print_progress method. This leads to problems when the last access to the progress bar sets...

[dnf5] collaborate on `libpowerloader` for repodata / package downloading

1

Hi all, I wanted to start a more formal discussion on collaborating on the [`powerloader`](https://github.com/mamba-org/powerloader) effort. As we've discussed before, it's a port of parts of `librepo` to C++ (only...
