Re: [gentoo-dev] gcc-4.2 / gcc-4.3 plans
So the point is, our current 2.6.24 kernel is safe. I can *not* confirm this. Just some days ago, I compiled hardened-sources-2.6.24 (which uses genpatches-2.6.24-5; current gentoo-sources uses genpatches-2.6.24-6, but the difference is obviously not important here [it involves just an #include for some exotic hardwar]). Result: Compiles fine with gcc-4.3 on x86 but dies immediately at boot (before printing anything) unless acpi=off is used. (And just to be sure, I disabled every acpi feature except general acpi support - same result). It is certainly a compiler problem, because with gcc-4.2 exactly the same kernel configuration (and even on amd64 with gcc-4.3 and analogous configuration) has no problem. -- gentoo-dev@lists.gentoo.org mailing list

Presuming you're adding the direction-flag patch to 4.3.0 so it doesn't break people on a kernel earlier than 2.6.25? I didn't see it in a quick glance at the patch tarball.

Presuming you're adding the direction-flag patch to 4.3.0 so it doesn't break people on a kernel earlier than 2.6.25? I didn't see it in a quick glance at the patch tarball. i had no plans to revert the behavior in question. i could be persuaded to carry such a patch though until 2.6.25 goes stable and gcc-4.3 goes stable. presumably the time frame of both of those should be long enough. also, you'll have to provide a URL to said change. i havent seen a patch for it in my random driftings on the interweb. -mike signature.asc Description: This is a digitally signed message part.
