[Bug other/21319] Please add the feature of switching target at runtime
--- Additional Comments From pinskia at gcc dot gnu dot org 2005-05-01 16:02 --- This was a very long term goal of the hooking GCC but then it was proved that it slowed down the compiler too much. -- What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed||1 Last reconfirmed|-00-00 00:00:00 |2005-05-01 16:02:19 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21319

Like configure --with-arch-i686 --with-arch-arm... Yes that would slow down the compiler as right now we have macros for some target dependent controls and then they have to be changed to function calls which slow down the compiler. I think it slowed down the compiler about 1-5% IIRC. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21319

--- Additional Comments From radek at podgorny dot cz 2005-05-01 16:35 --- Oh, I see. Anyway, is 1-5% a major slowdown? I think it's still a good penalty if it saves all the headaches... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21319
