Sparse 0.5.2 released

Jump to: navigation, search

The latest release of sparse have been pushed to the official repository. It's a smaller release than the previous one but it contains some important changes to not be flooded by unimportant warnings while compiling the kernel.

The most notable changes are:

  • better tracking and handling of expression constness
  • fix bug with variadic macros
  • less warnings on unknown attributes (none by default now)
  • teach sparse about __builtin_{isinf_sign,isfinite,isnan}
  • various update to the documentation
  • do selfcheck with the locally built sparse
  • some fixes or improvements for build (armhf, GNU/kfreebsd, ...)
  • also evaluate files included via -include


Many thanks to everyone involved.
