I’m not an IDE man. But, ever since GNAT Studio became much more reliable a few years ago, it’s been a pleasure to use, and unlike Dmitry who, I believe, develops on Windows, the graphical debugger works perfectly on Linux. So I use GNAT Studio for both 8-bit microcontrollers and 64-bit programs, with a fully functional graphical debugger in both cases.
On Linux, you have field tested documentation here: https://github.com/sowebio/aide-doc
Have fun !
