Description Klaus Kusche 2002-08-07 05:31:09 UTC

When trying to install gentoo linux, or to reinstall / update glibc 2.2.5 with
gcc 3.1, with -msse2 or -march=pentium4 in make.conf, it fails with a gcc
internal compiler error (see gcc gnats system, bug id `target/7486'.

I've to run all my stage2/3 compiles with at most -march=pentium3.

Is it possible to automatically reduce -march=pentium4 to pentium3 in the ebuild
 script of glibc when gcc 3.1 is used, to be able to set -march=pentium4 in
make.conf for all other builds?

It is.  I did it for a few (mozilla, xfree comes to mind).  I however think
that it should be fixed gcc side, so will appreciate it if you can submit
a full report with the gcc devs.  I did so for xfree and -march=pentium4.

Comment 2 Klaus Kusche 2002-08-08 04:25:50 UTC

I did (nr 7486). Status is still "open/unassigned". Their bug handling seems to
be much slower than Gentoo's.

I'm afraid waiting for help from their side will take some time...
(but I can live with -march=pentium3 in my make.conf in the mean time).

Yep :(  Anyhow, a gcc issue.
