-march=k6 broken in 2.96 ?

[Remi Guyomarch <rguyom at mail dot dotcom dot fr>]

Hi,

I can't bootstrap (at least) the last 4 snapshots with
BOOT_CFLAGS="-O2 -march=k6 -s -pipe".

I can bootstrap the compiler using BOOT_CFLAGS="-O2 -mcpu=pentiumpro
-s -pipe", but the resulting compiler still ICE when invoked with
"-march=k6" on some sources.

I got the exact same problem with the 11-02 and 10-25 snapshots.

I can't bootstrap 10-19 either, but the error is a bit different :

I can't say much about previous snapshots because I got other problems
which prevented the bootstrap process from reaching the point where
stage1 try to compile stage2.

I'm using FreeBSD 3.3-STABLE.
