--- Comment #1 from Paulo J. Matos <pa...@matos-sorge.com> 2013-05-08 08:58:54 UTC --- I am revisiting this bug and it seems that there's just an extra work, nothing specially unexplained and the correct URL for the problem is: http://gcc.gnu.org/onlinedocs/gccint/LTO-Overview.html#LTO-Overview I will submit a patch to fix this.
