> > Treesit-defun-tactic being ’nested isn’t the problem here, at least not the direct cause of the problem. c-ts-mode doesn’t consider switch cases or if-else statements as defuns. It only considers function, struct, enum, union, as defun. So in a preprocessed C source file, C-M-a will move point to the beginning of the function, line E. It does not in this particular file because tree-sitter is thrown off by the SWITCH() and CASE() macro: it can’t tell what they are and parses them as function definitions.

Done.
