[Xen-devel] bad register name `%sil'' when building debug enabled xen 3.3.1 with gcc 4.4.0 on fedora 11
Hello!
Has anyone seen this error?:
traps.c: Assembler messages:
traps.c:1343: Error: bad register name `%sil''
make[4]: *** [traps.o] Error 1
make[4]: Leaving directory
`/root/rpmbuild/BUILD/xen-3.3.1/xen/arch/x86''
make[3]: *** [/root/rpmbuild/BUILD/xen-3.3.1/xen/arch/x86/built_in.o] Error 2
I''m trying to rebuild Fedora xen-3.3.1-11.fc11.src.rpm with debugging
enabled ("debug=y verbose=y crash_debug=y").
Normal non-debug build succeeds fine without errors.. gcc bug? xen bug?
Thanks!

I will fix for 3.4.0 and 3.3.1. You can use the attached patch to fix your build. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Thanks again.
