The list could be created by the build process. Not sure it would be
a lot of help, though.
The reason gdb-mi requests the source file list is to run
`gdb-init-buffer' in any buffer that contains one of those files.
This function sets up the toolbar and gud-minor-mode, and if
gud-tooltip-mode is on, does some processing of macros in the
(defun gdb-init-buffer ()
(set (make-local-variable 'gud-minor-mode) 'gdbmi)
(set (make-local-variable 'tool-bar-map) gud-tool-bar-map)
(add-hook 'after-save-hook 'gdb-create-define-alist nil t)))
(see `gdb-create-define-alist' as well).
If you've been using gud-tooltip-mode, then, turning it off will speed
up startup. If that doesn't help, benchmark gdb's
"-file-list-exec-source-files" command and see if it's worth caching
the result in Elisp to save some time.
