Caveats

    +
  • + On Arm targets (arm*-*-*), + a bug + in the implementation of the procedure call standard (AAPCS) + in the GCC 6, 7 and 8 releases has been fixed: a structure + containing a bit-field based on a 64-bit integral type and where + no other element in a structure required 64-bit alignment could be + passed incorrectly to functions. This is an ABI change. If the + option -Wpsabi is enabled (on by default) the + compiler will emit a diagnostic note for code that might be + affected. +
