arm-uclinuxfdpiceabi, and the C library is uclibc-ng. +
  • Support has been added for the Arm EABI on NetBSD through the + arm*-*-netbsdelf-*eabi* triplet. +
    • +
  • The handling of 64-bit integer operations has been significantly reworked + and improved leading to improved performance and reduced stack usage when using + 64-bit integral data types. The option -mneon-for-64bits is now + deprecated and will be removed in a future release.
    • +
  • + Support has been added for the following processors + (GCC identifiers in parentheses): +
      +
    • Arm Cortex-A77 (cortex-a77).
      • +
    • Arm Cortex-A76AE (cortex-a76ae).
      • +
    • Arm Cortex-M35P (cortex-m35p).
      • +
    + The GCC identifiers can be used + as arguments to the -mcpu or -mtune options, + for example: -mcpu=cortex-a77 or + -mtune=cortex-m35p. +
    • +
  • Support has been extended for the ACLE + + data-processing intrinsics to include 32-bit SIMD, saturating arithmetic, + 16-bit multiplication and other related intrinsics aimed at DSP algorithm + optimization. +

    AVR

    +
      +
    • Support for the XMEGA-like devices +
      + ATtiny202, ATtiny204, ATtiny402, ATtiny404, ATtiny406, ATtiny804, + ATtiny806, ATtiny807, ATtiny1604, ATtiny1606, ATtiny1607, ATmega808, + ATmega809, ATmega1608, ATmega1609, ATmega3208, ATmega3209, + ATmega4808, ATmega4809 +
      + has been added. +
      • +
    • + A new command line option -nodevicespecs has been added. + It allows to provide a custom device-specs file by means of +
      + avr-gcc -nodevicespecs -specs=my-spec-file <options> +
      + and without the need to provide options -B and + -mmcu=. + See + AVR + command line options for details. + This feature is also available in v9.3+ and v8.4+. +
      • +
    • + New command line options -mdouble=[32,64] and + -mlong-double=[32,64] have been added. They allow + to chose the size (in bits) of the double and + long double types, respectively. Whether or not the + mentioned layouts are available, whether the options act + as a multilib option, and what is the default for either option + is controlled by the new + AVR configure + options + --with-double= and --with-long-double=. +
      • +
    • + A new configure option --with-libf7= has been added. + It controls to which level avr-libgcc provides 64-bit floating point + support by means of + Libf7. +
      • +
    • + A new configure option --with-double-comparison= has been + added. It's unlikely you need to set this option by hand. +
