./libgcc2.c:3356: Internal compiler error in distribute_notes, at combine.c:12481

[Felix von Leitner <felix at convergence dot de>]

I am trying to create a cross compiler for ppc-linux on a alphaev6-linux
box.

This internal compiler error happened when I tried to compile
egcs-20000821 targeting ppc-linux on my alphaev6-linux box.

This is the full command that failed:

xgcc was compiled with gcc-2.95.2 using "-pipe -O2" as CFLAGS (i.e. -pipe instead of -g).



I tried to cross-compile gcc-2.95.2, too, but it also failed:

Is there a way to create a cross compiler for ppc-linux on
alphaev6-linux that is known to work?
