Fri Feb 21 10:54:54 UTC 2025 - Matwey Kornilov <matwey.kornilov@gmail.com>

- update to 2.2.1
  * General:
    - Project moved to Github
    - Support for many new devices has been added, like devices from the
      AVR 0-series, 1-series, 2-series, AVR-Dx and AVR-Ex, but also for
      some older devices.
    - Parts of the user manual have been reworked, like the inline assembly
      Cookbook and the documentation of memory sections.
    - The multilib layout of the library, and what device belongs to which
      multilib variant, is no more hard coded in AVR-LibC but follows the
      compiler's multilib layout.
  * Improvements and additions:
    - Add support to new multilib layout / 64-bit [long] double compiler
      (Issues #642, #670)
    - Added support for new devices (Issue #824):
      ATtiny202 ATtiny204 ATtiny212 ATtiny214 ATtiny402 ATtiny404
      ATtiny406 ATtiny412 ATtiny414 ATtiny416 ATtiny417 ATtiny424
      ATtiny426 ATtiny427 ATtiny804 ATtiny806 ATtiny807 ATtiny814
      ATtiny816 ATtiny817 ATtiny824 ATtiny826 ATtiny827 ATtiny1604
      ATtiny1606 ATtiny1607 ATtiny1614 ATtiny1616 ATtiny1617 ATtiny1624
      ATtiny1626 ATtiny1627 ATtiny3214 ATtiny3216 ATtiny3217 ATtiny3224
      ATtiny3226 ATtiny3227 ATmega808 ATmega809 ATmega1608 ATmega1609
      ATmega3208 ATmega3209 ATmega4808 ATmega4809
    - Added support for AVR-Dx devices (Issue #881):
      AVR16DD14 AVR16DD20 AVR16DD28 AVR16DD32 AVR32DA28 AVR32DA32
      AVR32DA48 AVR32DB28 AVR32DB32 AVR32DB48 AVR32DD14 AVR32DD20
      AVR32DD28 AVR32DD32 AVR64DA28 AVR64DA32 AVR64DA48 AVR64DA64
      AVR64DB28 AVR64DB32 AVR64DB48 AVR64DB64 AVR64DD14 AVR64DD20
      AVR64DD28 AVR64DD32 AVR128DA28 AVR128DA32 AVR128DA48 AVR128DA64
      AVR128DB28 AVR128DB32 AVR128DB48 AVR128DB64
      AVR64DU28 AVR64DU32
    - Added support for AVR-Ex devices:
      AVR16EA28 AVR16EA32 AVR16EA48 AVR16EB14 AVR16EB20 AVR16EB28 AVR16EB32
      AVR32EA28 AVR32EA32 AVR32EA48 AVR64EA28 AVR64EA32 AVR64EA48
    - Added support for Reduced Tiny devices:
      ATiny102 ATtiny104
    - Added support for Classic devices:
      ATmega168PB ATmega328PB ATmega324PB
    - Added a new module to lib<mcu>.a that can be used as part of the
      startup code by the compiler.  The compiler will link the code when
      a device from the AVR-Dx or AVR-Ex families uses a non-default layout
      of NVMCTRL_CTRLB.FLMAP (Issue #931, Binutils PR31124, GCC PR112944).
      For more details on the feature see the GCC v14 release notes at
      https://gcc.gnu.org/gcc-14/changes.html#avr
    - Added support for: strndup.
    - Added support for: PROGMEM_FAR, PSTR_FAR, strchr_PF.
    - Added support for ccp_write_spm() in avr/cpufunc.h
    - The delay routines no more include math.h but use built-in functions
      __builtin_fabs and __builtin_ceil instead of fabs and ceil.  This means
      the delay routines are now independent of -f[no-]freestanding (Issue 580).
    - Added macros pgm_read_qword, pgm_read_qword_near, pgm_read_qword_far.
    - Added inline functions to read from progmem that return a type as
      indicated by the function name, like char pgm_read_char (const char*).
      The functions adjust to -mint8, -mdouble= and -mlong-double=.
      Functions for fixed-width types are pgm_read_i64, pgm_read_u24, etc.
      * Functions that read from beyond 64 KiB are suffixed _far and take
        an uint_farptr_t as argument.
      * pgm_read_float has been turned from a macro that takes uint16_t to
        an inline function that takes const float*.
      * pgm_read_byte, pgm_read_word and pgm_read_dword remain as they were
        and still take an uint16_t argument for compatibility and legacy code.
    - Added experimental templates pgm_read<> and pgm_read_far<>.  They are
      only available when macro __pgm_read_template__ is defined.
    - Added EEPROM support for: double, long double, uint64_t (*_qword).
    - AVR-LibC does not use section .progmem.* any more for lookup tables and
      string literals.  Instead, .progmemx.* is used which does not require
      that the data resides in the lower 64 KiB of program memory.
      This means that on devices with more than 64 KiB of program memory,
      the ELPM instruction is used to read the data where formerly it was LPM.
      Hence code size and execution times on such devices will slightly
      increase for functions from the printf and scanf families, and for libm
      functions that use power series.  (Issue #962).
      Notice that only since Binutils v2.29 (PR21849), section .progmemx is
      located after the .text sections.
    - The startup code now defines symbols like __DATA_REGION__LENGTH__ and
      __DATA_REGION_ORIGIN__ according to the memories of the used AVR device
      (Issue #936).  These symbols are used by the default linker scripts to
      diagnose when the text or data region overflows.
      To date, only a core specific default value was used, but the devices
      that belong to the same core architecture have different memory sizes.
    - The pgm_read_* and pgm_read_*_far macros and functions now also work for
      the Reduced Tiny devices. (Issue #563).  The implementation assumes that
      GCC implements PR71948 which was added in v7.  Notice that on Reduced Tiny:
      * There is no need for PROGEMM at all because all const objects in static
        storage are located in program memory since Binutils v2.27 (PR20849).
      * Even when PROGMEM is used, no pgm_read functions or macros are required.
        See the GCC documentation on the __progmem__ attribute for Reduced Tiny.
  * Issues closed:
    - [patch #9543] Add avrxmega3 devices. #824
    - [bug #49567] Use meta-info from --print-multi-lib and
      --print-multi-directory #642
    - [bug #57071] Fix math.h and function names that block 64-bit
      double #670
    - Issue #476 [bug #32945] RAMPZ clobbered in far-pointer library.
      Functions from the far-pointer library in libc/pmstring like
      memcpy_PF that read from program memory using ELPM must set
      RAMPZ to the high byte of the 24-bit address.  On devices that
      don't use RAMPZ exclusively with ELPM, RAMPZ has to be reset when
      the function is finished.  These are devices with an EBI (External
      Bus Interface): ATxmega64A1, ATxmega64A1U, ATxmega128A1,
      ATxmega128A1U,  ATxmega128A4U.
    - Add device support to avr/power.h for:
      ATtiny441 ATtiny841
    - FDEV_SETUP_STREAM from stdio.h now works with C++ (Issue #898)
    - More than 80, mostly historic issues have been closed -- too many
      to mention all of them here
    - Fixed wrong prototypes of frexp, frexpf, frexpl in math.h (Issue #929)
    - time.h: function mktime() is off by 1h when [EU] DST is active (Issue #967)
