    New Targets and Target Specific Improvements

    +
      +
    • Support has beed added for instrinsic named address spaces + __pgm, __pgm1, …, __pgm5 + and __pgmx. These address spaces locate read-only data in + flash memory and allow reading from flash memory by means of vanilla + C instructions, i.e. without the need of (inline) assembler code.
      • +
    • Support for AVR-specific built-in functions has beed added.
      • +
    • Support has beed added for the built-in, 24-bit, signed and unsigned + integer types __int24 and __uint24.
      • +
    • New command-line options -maccumulate-args, + -mbranch-cost=cost and -mstrict-X + were added to allow better fine-tuning of code optimization.
      • +
    • Many optimizations to: +
        +
      • 64-bit integer arithmetic
        • +
      • Widening multiplication
        • +
      • Integer divide-by-constant
        • +
      • Generic built-in functions + like __builtin_ffs*, __builtin_clz*, etc.
        • +
      • If-else decision trees generated by switch instructions
        • +
      • Merging of data in .progmem
        • +
      • Devices with 8-bit wide stack pointer register
        • +
      • …
        • +
      +
    • Better documentation: +
        +
      • Handling of EIND and indirect jumps on devices with + more than 128 KiB of program memory.
        • +
      • AVR-specific built-in macros.
