commit r16-8379-g7b3ec84f0a9a4f86fa9cfb0e1b9e8401e89cef3c Author: Richard Biener <[email protected]> Date: Tue Mar 31 19:48:30 2026 +0200 middle-end/124634 - add internal function internals documentation section The following adds documentation for internal function details. I have populated the internal function tables via macro expansion of the internal-fn.def file, so it's quite boiler-plate and asks for manual amending in more complicated places. Without such a place it's quite difficult to tell people to document things when they add new internal functions. We might want to split the table into two, separating direct internal functions from others. I have added some overall sentences related to internal functions and builtins but left the API section as a FIXME. I'm not sure we need a separate index - I have used IFN_ prefixes which separates them nicely. Removing those would warrant a separate index. I've placed the contents after the GENERIC/GIMPLE chapters. v2: wrap long lines and integrate Sandras changes Built and inspected using texinfo 7.1.
