[FFmpeg-devel] [PATCH 0/7] Add strict-aliasing-safe type punning macros

[Mans Rullgard]

This patch series adds helpers for safe type punning without tripping
over any strict aliasing optimisations.

Please comment.

Mans Rullgard (7):
  Check for may_alias gcc attribute support
  Define av_alias if supported by compiler
  Add alias-safe union typedefs
  Use alias-safe types in AV_[RW] macros
  Use alias-safe types in AV_COPY/SWAP/ZERO macros
  Add AV_COPY32
  Add alias-safe aligned AV_[RW]N macros
