Hello,
we have to select a GCC version for the RTEMS 6 release. Currently, GCC
10 is used, however, with the release of GCC 10.4 this year it will
reach its end of life. Other options are GCC 11 and 12. GCC 12 will be
released in the next weeks. It has some nice features:
* Initialization of stack variables:
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-ftrivial-auto-var-init
* Improved static analysis with -fanalyzer
* Improved gcov support, with the ability to back port changes from GCC 13:
https://gcc.gnu.org/pipermail/gcc-patches/2022-April/593536.html
* Upstream maintenance for the next three years
The draw back is that it is brand new.
The Ada support is broken in GCC 12 for most targets:
