Subject: [Qemu-devel] alpha - syscalls can return two values
Date: Tue, 11 Nov 2008 15:14:47 -0500 (EST)	[thread overview]
Message-ID: <20081111151233.C64870@stanley.csl.cornell.edu> (raw)

Hello

On the Alpha architecture, system calls can return two values, one in 
register $0 and one in register $1.  This is unusual, so there is no 
mechanism I can see in linux-user/syscall.c for handling this properly.

What would be the best way to handle this?

This is needed to implement the getxuid and getxgid syscalls.  Without 
these, the spec2k perlbmk fails to run.

Vince
