--- Comment #40 from Oleg Endo <olegendo at gcc dot gnu.org> --- (In reply to Rich Felker from comment #39) > Oleg, do you have rights under your copyright assignment agreement to > dual-license the libgcc part of the patch under GPLv2 so it could be > included in the kernel, and if so, would you be willing to do so? If I understand it correctly, it should be OK. Please contact me directly about this. If possible, please also add the other people who want this to the CC list. > I agree it > would be cleaner for the kernel not to duplicate libgcc code, but getting in > a simple patch to update the code that's there would be a lot easier than > the build-architectural change of using libgcc itself in the kernel, which > is an issue I'd really rather not fight with the kernel developers on if > they disagree. :-) A quick search for "libgcc linux kernel" tells the story about this. Unfortunately, you are right.
