bug#10580: 24.0.92; gdb initialization takes more than one minute at 100% CPU

[Dov Grobgeld]

Yes, sorry. I discovered that I looked at an old version. The latest git version indeed allows disabling the -file-list-exec-source-files. I will use that option which indeed is a work around for the problem.

In addition, I filed a bug for gdb that it should uniq the filenames output by -file-list-exec-source-files.

I realized that all filelist-exec-source-files is used for is to turn on gdb minor mode for all files that are currently open in emacs. Perhaps we should turn the problem around by asking for a gdb function that answers the question whether a file is referenced by an executable. It would then be possible to loop over the emacs buffers and turn on gdb minor mode if the file is referenced by the new gdb session.

Regards,
Dov

You are looking at a very old version of gdb-mi.el.
