  • merge from dev [7450] [7452] [7456] [7457] [7458] [7459] [7460] [7461] [7464] [7465] [7466] [7467] [7468] [7469] [7482]
    • tweaked compiler options
      • activated -Weffc++
        • postfilter warnings where Scott Meyers' advices are too general.
          • base classes should not always have virtual destructors, since that renders tiny classes useless and
          • members should not always be initialized via initialization list, since that often violates the DRY principle
        • fix gcc's inability to detect that Noncopyable implements a private copy-ctor and op=
        • this slows down complete ARB recompilation by ~5%
    • added -Wold-style-cast (inactive)
    • removed -Wno-non-template-friend added in [7447]
  • postcompile.pl
    • added option —original to show unmodified compiler output
  • declared op= for classes which had a copy-ctor
  • moved op= macros to arbtools.h
  • derived classes containing pointers from Noncopyable (use Noncopyable virtually) or
  • made them copyable if needed (awt_mask_item, KnownDB, Code, AWT_registered_itemtype, GEN_gene, PosGene, PartialSequence, PlugIn, Range, Convaln_exception)
  • other related changes
    • user mask destruction working now
