Subject: 24.0.91; gdb-create-source-file-list and the documented behaviour
Date: Sun, 20 Nov 2011 22:41:26 +0530

I have set gdb-create-source-file-list to nil, but still gdb takes lot
of time to give the (gdb) prompt for binaries like linux kernel. Looking
at the source, I guess gdb-create-source-file-list check is not correct. We have


  ;; find source file and compilation directory here
  (gdb-input
                                        ; Needs GDB 6.2 onwards.
   (list "-file-list-exec-source-files" 'gdb-get-source-file-list))
  (if gdb-create-source-file-list
      (gdb-input
                                        ; Needs GDB 6.0 onwards.
       (list "-file-list-exec-source-file" 'gdb-get-source-file)))


Don't we need to conditionalize gdb-get-source-file-list call ?
Also "ready" mode line update is done in that function. I guess
that should be moved to gdb-get-source-file ?

IIUC, this was the bug that Nick was fixing in the following checkin, so
I'm closing it.  If it's not, please reopen.  Thanks.
