seems that is working with gcc-4.x but not gcc-3.4.x

I'll try to solve the issue later

[Comment 2 Daniele Viganò 2006-03-24 04:16:27 UTC]

Removing arm-user and armeb-user from TARGET_LIST in ebuild make qemu 0.8.0 compile under PPC with GCC 3.4.5.

[Comment 3 dimitrij wagner 2006-04-21 16:08:49 UTC]

Created attachment 85153 [details, diff]
modified header file cpu-all.h

the problem on ppc boxes is caused by a compiler switch ( __powerpc__ ) which enables the compilation of a code fragment ( inline assembly ).
the constraints list of that asm-statement is not correctly defined.
this patch corrects that constraints-list

Committed, thanks
