oh I found a way to set it:

+++ b/src/sim/syscall_emul.cc Tue Mar 31 21:07:27 2015 +0100
@@ -71,6 +71,9 @@
SyscallReturn retval = (*funcPtr)(this, callnum, process, tc);
+ if (retval.encodedValue() == 0)
+ tc->setCCReg(CCREG_C, 0);
+
if (retval.needsRetry()) {
DPRINTFS(SyscallVerbose, tc->getCpuPtr(), "syscall %s needs retry\n",
name);
Thanks
