On the other hand, new relocation +opcodes `hi8()`, `lo8()` and `hh8()` have been implemented for the STM8 port of GNU `as`. + +This is meant to be used with a fork of SDCC I created which generates GNU `as`-compatible assembly +files via the new `--gas`, `--function-sections` and `--data-sections` switches. These changes have not been integrated into SDCC's main branch, so you +can find them at https://github.com/XaviDCR92/sdcc-gas . +## Usage +``` +./patch_binutils.sh +./configure_binutils.sh +cd binutils-2.30/ +make +sudo make install +``` +## Examples +You can find a small working code example of the new capabilities provided by this fork at +https://github.com/XaviDCR92/stm8-dce-example . +## Thanks +Thanks to **arehnman**, who created the original package and helped me out **a lot** to get this working. +Also, thanks to the SDCC developers to their hard work in providing an interesting alternative to +existing STM8 propietary compilers. |
