    • +
  • When a block other than the last 32 KiB block is used to store .rodata, then NVMCTRL_CTRLB.FLMAP must be initialized accordingly by hand, or a version of AVR-LibC that implements  with a version of Binutils that implements PR31124, which is the case for Binutils v2.42 and up.
    • +
  • The implementation consists of two parts: +
      +
    1. Binutils support new emulations avrxmega2_flmap and + avrxmega4_flmap. The sole purpose of these emulations + is to provide adjusted default linker description files. + Apart from that, these emulations behave exactly the same like + avrxmega2 resp. avrxmega4.
      2. +
    2. The compiler uses a + device-specs + file which links the program + with -mavrxmega2_flmap or -mavrxmega2 + depending on -m[no-]rodata-in-ram; and similar + for -mavrxmega4[_flmap].
      3. +
    + This means the feature can be used with older compiler or Binutils + versions; all what's needed is an adjusted linker script and + a custom device-specs file. +
  • A new compiler option -m[no]-rodata-in-ram has been added. ----------------------------------------------------------------------- Summary of changes: htdocs/gcc-14/changes.html | 22 ++++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-) hooks/post-receive -- gcc-wwwdocs
