Not really much other than tangential mentions. I did write an addendum to the OP going over the secondary stack as well as where you still use normal dynamic allocation in Ada: https://nytpu.com/gemlog/2024-12-27-2

All my knowledge on it comes from some documentation on configuring the secondary stack for embedded targets and from comments+diagrams in the GCC GNAT source code (and maybe I saw a conversation on it on the comp.lang.ada Usenet group at some point…): https://docs.adacore.com/gnat_ugx-docs/html/gnat_ugx/gnat_ug... https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/ada/libgnat/...
